Fig. 2 is a flow chart of a memory processing method in an embodiment. The memory processing method in this embodiment is described by taking the memory processing method running on the electronic device in Fig. 1 as an example. As shown in Fig. 2, the memory processing method includes steps 202 to 206.

Step 202: Obtain a memory page identification set corresponding to the currently running application.

Among them, the currently running application refers to the application that is currently in operation, which may specifically include at least one of a foreground application and a background application. The memory page identification set is used to store the identification corresponding to the memory page. The foreground application refers to the application that the user is operating on the electronic device, and the background application refers to the application that the user is not operating but is running in the background of the electronic device.

Specifically, the electronic device can obtain the currently running application and obtain the memory page identification set corresponding to the currently running application. The memory page identification set is used to record the identification of the memory page corresponding to the currently running application.

In one embodiment, the memory page identification set is used to record the identification of the memory pages used by the currently running application.

In one embodiment, when the foreground application changes, the electronic device may obtain the currently running application and obtain the memory page identification set corresponding to the currently running application.

Step 204: Determine the foreground application and the background application in the currently running application.

Specifically, the electronic device can determine the currently running foreground application and the background application respectively from the currently running application programs.

In one embodiment, the electronic device can determine the foreground application and the background application in the currently running application through the running task list. The electronic device can obtain the running task list within a preset time, and determine the foreground application and the background application in the currently running application through the running task list. That is, the electronic device can obtain a list of a group of recently run tasks, sorted by time, with the most recently used application at the front, then the front is the foreground application, and the rest of the applications are background applications.

In one embodiment, the electronic device can obtain the application process information list running on itself, and determine the foreground application and the background application in the currently running application according to the application process information list. When the process contains background running code, the application corresponding to the process is determined to be a background application. When a process in the application process information list is in the display state of the front-end interface, the application corresponding to the process is determined to be a foreground application.

For example, the foreground application switches from application A to application B, and application A continues to run in the background. Then, application A and application B are the currently running applications, application B is the foreground application, and application A is the background application.

Step 206, obtain the foreground memory page identifier corresponding to the foreground application in the memory page identifier set, and adjust the priority of the foreground memory page corresponding to the foreground memory page identifier; the adjusted priority of the foreground memory page is higher than the priority of the background memory page of the background application.

The foreground memory page identifier refers to the identifier of the memory page corresponding to the foreground application, the foreground memory page refers to the memory page corresponding to the foreground application, and the background memory page refers to the memory page corresponding to the background application.

Specifically, the priority refers to the priority of memory use. The electronic device can obtain the foreground memory page identifier corresponding to the foreground application from the memory page identifier set. The electronic device can determine the foreground memory page corresponding to the foreground memory page identifier and adjust the priority of the foreground memory page to increase the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page of the background application.

In one embodiment, the electronic device may also obtain a background memory page identifier corresponding to the background application from the memory page identifier set. The background memory page identifier refers to the identifier of the memory page corresponding to the background application. The electronic device may determine the background memory page corresponding to the background memory page identifier, and the electronic device may adjust the priority of the foreground memory page to increase the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page.

In this embodiment, the memory page identification set corresponding to the currently running application is obtained, and the foreground application and the background application in the currently running application are determined, so that the currently running application can be divided into the foreground application and the background application. By obtaining the foreground memory page identification corresponding to the foreground application in the memory page identification set, the memory pages of the foreground application and the background application can be distinguished to adjust the priority of the foreground memory page corresponding to the foreground memory page identification, and the priority of the foreground memory page can be improved so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page of the background application. By improving the priority of the foreground memory page, the foreground application can obtain a higher memory usage priority, the foreground application has lower latency, and the response speed is faster.

In one embodiment, obtaining a foreground memory page identifier corresponding to a foreground application in a memory page identifier set and adjusting a priority of a foreground memory page corresponding to the foreground memory page identifier includes:

Obtain the foreground memory page identifier corresponding to the foreground application in the memory page identifier set, and determine the linked list where the foreground memory page corresponding to the foreground memory page identifier is located; if the foreground memory page is in the inactive linked list, move the foreground memory page to the active linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

Among them, the active linked list is used to store frequently accessed active memory pages. The inactive linked list is used to store memory pages that may be associated with one or more processes but are not frequently used.

Specifically, the electronic device obtains the foreground memory page identifier corresponding to the foreground application from the memory page identifier set. The electronic device determines the foreground memory page corresponding to the foreground memory page identifier, and determines the linked list where the foreground memory page is located. The linked list includes an active linked list and an inactive linked list. The priority of the active linked list in using memory is higher than that of the inactive linked list.

When the foreground memory page is in the inactive linked list, it means that the foreground memory page is placed in a queue that is not frequently accessed, and the electronic device moves the foreground memory page to the active linked list, thereby moving the foreground memory page to the frequently accessed queue.

In one embodiment, the electronic device may determine each foreground memory page in the inactive linked list, and move each foreground memory page from the inactive linked list to the active linked list.

In one embodiment, the linked list is an LRU (Least Recently Used) linked list, and the LRU linked list is divided into an active linked list and an inactive linked list. The active linked list is represented as an active linked list, and the inactive linked list is represented as an inactive linked list.

In this embodiment, the priority of the active linked list is higher than the priority of the inactive linked list. The foreground memory page corresponding to the foreground application is placed in the active linked list, and the foreground memory page can be placed in the queue that is frequently accessed, thereby increasing the priority of the foreground application in using memory, and reducing the number of page repetitive loading errors of the foreground application. Page repetitive loading error (Foreground Aware Eviction Scheme, referred to as FAE) refers to a process in which a page is loaded into the memory for the first time, and after a period of non-access, the memory space of the page is released, and then when it is accessed again, a page fault interrupt is generated again, and the relevant data needs to be read from the external memory to the memory again. The time difference between reading the external memory and directly reading the memory is very large, which will cause a response delay in the application. In this embodiment, by increasing the priority of the foreground application in using memory, the number of page repetitive loading errors of the foreground application is reduced, thereby speeding up the startup speed of the foreground application.

In one embodiment, the method further includes: if the foreground memory page is in the active linked list, retaining the foreground memory page in the active linked list.

Specifically, the electronic device obtains each foreground memory page identifier corresponding to the foreground application from the memory page identifier set. For each foreground memory page identifier, the electronic device determines the foreground memory page corresponding to the foreground memory page identifier to obtain each foreground memory page. For each foreground memory page, the electronic device determines the linked list where the foreground memory page is located. For each foreground memory page, it is determined whether the foreground memory page is in the active linked list. In the case where the foreground memory page is in the active linked list, the foreground memory page is not moved to keep the foreground memory page in the active linked list.

In this embodiment, when the foreground memory page is in the active linked list, the foreground memory page is retained in the active linked list to keep the foreground memory page in a frequently accessed queue, which can increase the priority of the foreground application in using memory, thereby improving the memory response of the foreground application and improving the user experience of the foreground application.

In one embodiment, the method also includes: obtaining a background memory page identifier corresponding to a background application in a memory page identifier set, and adjusting the priority of a background memory page corresponding to the background memory page identifier; the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page.

Specifically, the electronic device may obtain a foreground memory page identifier corresponding to the foreground application from the memory page identifier set, determine the foreground memory page corresponding to the foreground memory page identifier, and adjust the priority of the foreground memory page to increase the priority of the foreground memory page.

Furthermore, the electronic device may also obtain a background memory page identifier corresponding to the background application from the memory page identifier set. The electronic device may determine the background memory page corresponding to the background memory page identifier, and the electronic device may adjust the priority of the background memory page to reduce the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the adjusted priority of the background memory page.

In one embodiment, the electronic device can determine the foreground memory page corresponding to the foreground memory page identifier and the background memory page corresponding to the background memory page identifier, and the electronic device can obtain the priorities of the foreground memory page and the background memory page, and compare the priorities of the foreground memory page and the background memory page. When the priority of the foreground memory page is lower than the priority of the background memory page, the priority of the foreground memory page is adjusted to increase the priority of the foreground memory page, so that the priority of the foreground memory page is higher than the priority of the background memory page.

In one embodiment, when the priority of the foreground memory page is lower than the priority of the background memory page, the electronic device may adjust the priority of the background memory page to lower the priority of the background memory page so that the priority of the foreground memory page is higher than the priority of the background memory page.

In one embodiment, when the priority of the foreground memory page is lower than the priority of the background memory page, the electronic device may adjust the priorities of the foreground memory page and the background memory page at the same time to increase the priority of the foreground memory page and lower the priority of the background memory page, so that the priority of the foreground memory page is higher than the priority of the background memory page.

In this embodiment, by obtaining the background memory page identifier corresponding to the background application in the memory page identifier set, the background memory page that the background application is using can be quickly and accurately found through the background memory page identifier. By adjusting the priority of the background memory page corresponding to the background memory page identifier, the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page. By increasing the priority of the foreground memory page, the foreground application obtains a higher memory usage priority and the background application obtains a lower memory usage priority, which can reduce the memory demand of the background application and improve the memory response of the foreground application.

In one embodiment, obtaining a background memory page identifier corresponding to a background application in a memory page identifier set and adjusting a priority of a background memory page corresponding to the background memory page identifier includes:

Obtain the background memory page identifier corresponding to the background application in the memory page identifier set, and determine the linked list where the background memory page corresponding to the background memory page identifier is located; if the background memory page is in the active linked list, move the background memory page to the inactive linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

Specifically, the electronic device obtains a background memory page identifier corresponding to the background application from the memory page identifier set. The electronic device determines the background memory page corresponding to the background memory page identifier, and determines the linked list where the background memory page is located. The linked list includes an active linked list and an inactive linked list. The priority of the active linked list in using memory is higher than that of the inactive linked list.

When the background memory page is in the active linked list, it means that the background memory page is placed in the frequently accessed queue, and the electronic device moves the background memory page to the active linked list, thereby moving the background memory page to the queue that is not frequently accessed. The same process is performed for each background memory page to move each background memory page in the active linked list to the inactive linked list.

In this embodiment, the priority of the active linked list is higher than that of the inactive linked list. For the background memory page in the active linked list, the background memory page is moved to the inactive linked list, and the background memory page can be moved to a queue that is not frequently accessed, thereby reducing the priority of the background application to use memory and speeding up the startup speed of the foreground application.

In one embodiment, the method further includes: if the background memory page is in the inactive linked list, retaining the background memory page in the inactive linked list.

Specifically, the electronic device obtains each background memory page identifier corresponding to the background application from the memory page identifier set. For each background memory page identifier, the electronic device determines the background memory page corresponding to the background memory page identifier to obtain each background memory page. For each background memory page, the electronic device determines the linked list where the background memory page is located. For each background memory page, it is determined whether the background memory page is in an inactive linked list. In the case that the background memory page is in an inactive linked list, the background memory page is moved to keep the background memory page in the active linked list.

In this embodiment, when the background memory page is in the inactive linked list, the background memory page is retained in the inactive linked list to keep the background memory page in a queue that is not frequently accessed, thereby reducing the memory demand of the background application and providing more memory for the foreground application.

In one embodiment, the method further includes: determining clean memory pages in the inactive linked list, and recycling the clean memory pages.

The clean memory page refers to an unmodified memory page in the memory space, and the clean memory page may be one or more memory pages.

Specifically, the electronic device may determine the clean memory pages in the inactive linked list, and recycle the clean memory pages through a recycling process, for example, recycling the clean memory pages in the inactive linked list through a kswapd process.

In this embodiment, by recycling clean memory pages in the inactive linked list, available memory space can be increased to ensure the normal operation of the application.

In one embodiment, the method further includes: determining dirty memory pages in the inactive linked list, and recycling the dirty memory pages.

The dirty memory page refers to a modified memory page in the memory space, and the dirty memory page may be one or more memory pages.

Specifically, the electronic device may determine the dirty memory pages in the inactive linked list, and perform storage and recycling processing on the dirty memory pages through a recycling process, such as performing storage and recycling processing on the dirty memory pages through a kdflush process.

In one embodiment, the method further includes: determining clean memory pages and dirty memory pages in the inactive linked list, and recycling the clean memory pages and dirty memory pages in turn based on the fact that the priority of the clean memory pages is higher than that of the dirty memory pages.

Specifically, the electronic device can directly recycle clean memory pages, but before recycling dirty memory pages, they need to be stored, and the processing time of dirty memory pages is longer than that of clean memory pages. In this embodiment, clean memory pages are recycled first, which can improve the efficiency of memory recycling.

In one embodiment, as shown in FIG. 3 , obtaining a foreground memory page identifier corresponding to a foreground application in a memory page identifier set and adjusting a priority of a foreground memory page corresponding to the foreground memory page identifier includes:

Step 302: Obtain a first application identifier of a foreground application and a second application identifier of a background application.

Specifically, when the currently running application is divided into a foreground application and a background application, the application identifier of the application is correspondingly divided into a first application identifier and a second application identifier. The first application identifier refers to the application identifier corresponding to the foreground application, and the second application identifier refers to the application identifier corresponding to the background application. After the electronic device determines the currently running application, it can determine the foreground application and the background application in the currently running application. The electronic device can obtain the first application identifier corresponding to the foreground application and the second application identifier corresponding to the background application.

In one embodiment, the electronic device can obtain a configuration file of a foreground application through a kernel, and obtain a first application identifier of the foreground application from the configuration file of the foreground application. The electronic device can obtain a configuration file of a background application through a kernel, and obtain a second application identifier of the background application from the configuration file of the background application.

Step 304: Determine a foreground memory page identifier that matches the first application identifier from the memory page identifier set.

Specifically, the electronic device matches the first application identifier with each memory page identifier in the memory page identifier set to determine the memory page identifier that matches the first application identifier. The electronic device determines the memory page identifier that matches the first application identifier in the memory page identifier set as the foreground memory page identifier. In the same processing manner, the electronic device can filter out each foreground memory page identifier that matches the first application identifier from the memory page identifier set.

Step 306: adjust the priority of the foreground memory page corresponding to the foreground memory page identifier.

Specifically, the electronic device may determine the foreground memory page corresponding to each foreground memory page identifier to adjust the priority of each foreground memory page so that the priority of each foreground memory page is higher than the priority of the background memory page.

In one embodiment, after determining each foreground memory page, the electronic device determines the priority of each foreground memory page and the priority of each background memory page, selects the foreground memory page with a lower priority than the background memory page, and increases the priority of the selected foreground memory page so that the priority of each foreground memory page is higher than the priority of the background memory page.

Obtain the background memory page identifier corresponding to the background application in the memory page identifier set, and adjust the priority of the background memory page corresponding to the background memory page identifier, including:

Step 308: Determine a background memory page identifier that matches the second application identifier from the memory page identifier set.

Specifically, the electronic device matches the second application identifier with each memory page identifier in the memory page identifier set to determine the memory page identifier that matches the second application identifier. The electronic device determines the memory page identifier that matches the second application identifier in the memory page identifier set as the background memory page identifier. In the same processing manner, the electronic device can filter out each background memory page identifier that matches the second application identifier from the memory page identifier set.

Step 310: Adjust the priority of the background memory page corresponding to the background memory page identifier.

Specifically, the electronic device can determine the background memory page corresponding to each background memory page identifier, and adjust the priority of each background memory page to reduce the priority of each background memory page so that the priority of each foreground memory page is higher than the priority of the background memory page.

In one embodiment, after determining each background memory page, the electronic device determines the priority of each foreground memory page and the priority of each background memory page, filters out background memory pages with a higher priority than the foreground memory page, and lowers the priority of the filtered background memory pages so that the priority of each foreground memory page is higher than the priority of the background memory page.

It can be understood that the execution order of steps 304-306 and steps 308-310 is not limited. The electronic device can execute steps 304-306 first and then 308-310, or execute steps 308-310 first and then 304-306, or execute steps 304-306 and 308-310 at the same time.

In this embodiment, the application identifier and memory page identifier of the same application program have a corresponding relationship. Then, through the first application identifier of the foreground application and the second application identifier of the background application, the matching foreground memory page identifier and the background memory page identifier can be found from the memory page identifier set, so as to adjust the priority of the foreground memory page corresponding to the foreground memory page identifier and the background memory page corresponding to the background memory page identifier, so as to increase the priority of the foreground memory page and reduce the priority of the background memory page, so that the foreground application obtains a higher memory usage priority and improves the startup speed of the foreground application.

In one embodiment, the method further includes: when there is an update to the application, configuring an application identifier for the updated application; and configuring a memory page identifier corresponding to the application identifier for the memory page of the updated application.

Among them, the application identifier refers to the unique identifier configured by the electronic device for its own application. For example, if application A, application B, and application C are installed on the electronic device, the electronic device can assign different application identifiers to application A, application B, and application C respectively. The application identifier and memory page identifier of the same application have a corresponding relationship. For example, the identifier of application A is A, and the memory page identifier corresponding to application A is A-1. Multiple memory pages of application A can use the same memory page identifier or different memory page identifiers, such as A-1, A-2, A-3, etc.

Specifically, when an electronic device has an update to its own application, it can determine that there is an updated application. The existence of an application update means that a new application has been downloaded to the electronic device or the version of the original application has been updated. The electronic device can configure the updated application to assign a unique application identifier to the application. The electronic device can determine the memory page corresponding to the updated application, configure a memory page identifier for the memory page corresponding to the updated application, and the configured memory page identifier has a corresponding relationship with the application identifier of the updated application.

In one embodiment, when the updated application is executed, the electronic device determines the memory page used by the updated application, and configures a memory page identifier corresponding to the application identifier for the used memory page.

In one embodiment, when installing an updated application, the electronic device configures an application identifier for the updated application.

In one embodiment, the application identifier and the memory page identifier of the same application may be the same. The electronic device may use the application identifier of the application to which the memory page belongs as the memory page identifier of the memory page.

In this embodiment, when there is an update to an application, an application identifier is configured for the updated application, and a unique application identifier can be assigned to each application. A memory page identifier corresponding to the application identifier is configured for the memory page of the updated application, and the memory page corresponding to each application can be accurately determined through the correspondence between the memory page identifier and the application identifier, so that the memory page corresponding to the foreground application and the memory page of the background application can be determined, so as to increase the priority of the memory page corresponding to the foreground application, obtain more memory space for the foreground application, and improve the memory usage efficiency.

As shown in Fig. 4, it is an architecture diagram of a memory processing method in an embodiment. A foreground aware eviction scheme (FAE) is set in the electronic device.

① Downloading applications to electronic devices, or updating the versions of applications installed in electronic devices;

② When the electronic device installs the application, the electronic device updates the configuration file of the application through the system framework, and the configuration file records the assigned application identifier. The application identifier can be saved in the system page table (Page Table Entry, referred to as PTE) and corresponds to the application package name. When the application is running, the application identifier of the application to which it belongs is marked in the memory page, and the application identifier is used as the memory page identifier of the memory page. In one embodiment, the electronic device uses the Android operating system, and the application runs on the Android operating system.

③When the foreground application of the electronic device changes, execute ④.

④The system framework determines the currently running foreground application and transmits the application ID of the foreground application.

⑤ The foreground-aware removal mechanism of the kernel can obtain the application identifiers of all application programs of the electronic device by accessing the configuration file. In one embodiment, the kernel can obtain the application identifier corresponding to the currently running application program through the foreground-aware removal mechanism.

⑥The kernel accesses the configuration file of the foreground application through the foreground perception removal mechanism and obtains the application identifier of the foreground application from the configuration file.

The foreground-aware removal mechanism can dynamically obtain the application ID of the foreground application, identify the foreground memory page of the foreground application through the application ID, and then adjust the priority of the foreground memory page of the foreground application in the active list and the inactive list, thereby improving the priority of the foreground application in using memory.

As shown in Figure 5, it is a schematic diagram of adjusting the priority of a memory page in one embodiment. The electronic device adjusts the priority of the memory page through an active linked list and an inactive linked list. The priority of the active linked list is higher than the priority of the inactive linked list. When the memory page identifier corresponds to the application identifier of the foreground application, it means that the memory page corresponding to the memory page identifier is the foreground memory page. When the memory page identifier corresponds to the application identifier of the background application, it means that the memory page corresponding to the memory page identifier is the background memory page.

When a memory page in the active linked list or the inactive linked list is accessed, the electronic device may determine whether the accessed memory page is a foreground memory page or a background memory page.

When the accessed memory page is a background memory page and the background memory page is in the active linked list, the electronic device moves the background memory page to the inactive linked list. When the accessed memory page is a background memory page and the background memory page is in the inactive linked list, the background memory page is retained in the inactive linked list.

When the accessed memory page is a foreground memory page and the foreground memory page is in the inactive linked list, the electronic device moves the foreground memory page to the active linked list. When the accessed memory page is a foreground memory page and the foreground memory page is in the active linked list, the electronic device retains the foreground memory page in the active linked list.

The electronic device starts to recycle memory pages from the tail of the inactive linked list. When the memory page is a clean memory page, the electronic device recycles the clean memory page through a recycling process. When the memory page is a dirty memory page, the dirty memory page is written back from the tail of the inactive linked list to the head of the inactive linked list.

Through the memory processing implemented in this embodiment, the memory allocation and recovery priorities of foreground applications and background applications are adjusted, and the probability of memory pages of foreground applications and background applications being recovered in the system can be increased, which can reduce the memory demand of background applications and improve the memory response of foreground applications, thereby improving the user experience of foreground applications.

In one embodiment, a memory processing method is provided, comprising:

The electronic device downloads an application or updates an installed application.

When installing an application, the electronic device configures an application identifier for the installed application.

Next, the electronic device configures a memory page identifier corresponding to the application identifier for the memory page of the updated application program.

When the foreground application changes, the electronic device obtains the memory page identification set corresponding to the currently running application.

Next, the electronic device determines a foreground application and a background application in the currently running application program, and obtains a first application identifier of the foreground application and a second application identifier of the background application.

Furthermore, the electronic device determines a foreground memory page identifier that matches the first application identifier from the memory page identifier set.

Next, the electronic device determines the linked list where the foreground memory page corresponding to the foreground memory page identifier is located.

Optionally, when the foreground memory page is in the inactive linked list, the electronic device moves the foreground memory page to the active linked list; when the foreground memory page is in the active linked list, the electronic device retains the foreground memory page in the active linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

Optionally, the electronic device determines a background memory page identifier that matches the second application identifier from the memory page identifier set, and determines a linked list where the background memory page corresponding to the background memory page identifier is located.

When the background memory page is in the active linked list, the electronic device moves the background memory page to the inactive linked list.

Optionally, when the background memory page is in the inactive linked list, the electronic device retains the background memory page in the inactive linked list.

Furthermore, the electronic device starts to recycle memory pages from the tail of the inactive linked list, and when the memory page is a clean memory page, the electronic device recycles the clean memory page through a recycling process. When the memory page is a dirty memory page, the dirty memory page is written back from the tail of the inactive linked list to the head of the inactive linked list.

In this embodiment, a unique application identifier is configured for each application, and when the application is running, the memory page of the application is marked with a memory page identifier corresponding to the application identifier. When the foreground application changes, the identifier of the memory page corresponding to the currently running application is recorded through the memory page identifier set, so that the foreground memory page corresponding to the foreground application and the background memory page corresponding to the background application can be accurately determined based on the corresponding relationship between the application identifier and the memory page identifier.

The priority of the active list is higher than that of the inactive list. Moving the foreground memory page from the inactive list to the active list can move the foreground memory page to the frequently accessed queue. When the foreground memory page is in the active list, the foreground memory page is retained in the active list to retain the foreground memory page in the frequently accessed queue, which can increase the priority of the foreground application in using memory and reduce the number of repeated page loading errors of the foreground application, thereby speeding up the startup speed of the foreground application.

For background memory pages in the active linked list, the background memory pages are moved to the inactive linked list, while the background memory pages in the inactive linked list are not moved. This can place all background memory pages in a queue that is not frequently accessed, which can reduce the priority of background applications in using memory and also speed up the startup speed of foreground applications.

In addition, by recycling clean memory pages in the inactive linked list, the available memory space can be increased to ensure the normal operation of the application.

It should be understood that, although the various steps in the flow charts of Fig. 2-Fig. 3 are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be performed in other orders. Moreover, at least a portion of the steps in Fig. 2-Fig. 3 may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these sub-steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

FIG6 is a block diagram of a memory processing device according to an embodiment. As shown in FIG6 , the memory processing device includes: an acquisition module 602, a determination module 604 and an adjustment module 606.

The acquisition module 602 is used to acquire the memory page identification set corresponding to the currently running application.

The determination module 604 is used to determine the foreground application and the background application in the currently running application.

The adjustment module 606 is used to obtain the foreground memory page identifier corresponding to the foreground application in the memory page identifier set, and adjust the priority of the foreground memory page corresponding to the foreground memory page identifier; the adjusted priority of the foreground memory page is higher than the priority of the background memory page of the background application.

In this embodiment, the memory page identification set corresponding to the currently running application is obtained, and the foreground application and the background application in the currently running application are determined, so that the currently running application can be divided into the foreground application and the background application. By obtaining the foreground memory page identification corresponding to the foreground application in the memory page identification set, the memory pages of the foreground application and the background application can be distinguished to adjust the priority of the foreground memory page corresponding to the foreground memory page identification, and the priority of the foreground memory page can be improved so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page of the background application. By improving the priority of the foreground memory page, the foreground application can obtain a higher memory usage priority, the foreground application has lower latency, and the response speed is faster.

In one embodiment, the adjustment module 606 is also used to: obtain the foreground memory page identifier corresponding to the foreground application in the memory page identifier set, determine the linked list where the foreground memory page corresponding to the foreground memory page identifier is located; when the foreground memory page is in the inactive linked list, move the foreground memory page to the active linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

In this embodiment, the priority of the active linked list is higher than the priority of the inactive linked list. The foreground memory page corresponding to the foreground application is placed in the active linked list, and the foreground memory page can be placed in a queue that is frequently accessed, thereby increasing the priority of the foreground application in using memory, and reducing the number of page repeated loading errors of the foreground application. Page repeated loading error refers to a process in which a page is loaded into the memory for the first time, and after not being accessed for a period of time, the memory space of the page is released, and then when it is accessed again, a page fault interrupt is generated again, and the relevant data needs to be read from the external memory to the memory again. The time difference between reading the external memory and directly reading the internal memory is very large, which will cause a response delay in the application. In this embodiment, by increasing the priority of the foreground application in using memory and reducing the number of page repeated loading errors of the foreground application, the startup speed of the foreground application can be accelerated.

In one embodiment, the adjustment module 606 is further configured to: when the foreground memory page is in the active linked list, retain the foreground memory page in the active linked list.

In this embodiment, when the foreground memory page is in the active linked list, the foreground memory page is retained in the active linked list to keep the foreground memory page in a frequently accessed queue, which can increase the priority of the foreground application in using memory, thereby improving the memory response of the foreground application and improving the user experience of the foreground application.

In one embodiment, the adjustment module 606 is also used to: obtain the background memory page identifier corresponding to the background application in the memory page identifier set, and adjust the priority of the background memory page corresponding to the background memory page identifier; the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page.

In this embodiment, by obtaining the background memory page identifier corresponding to the background application in the memory page identifier set, the background memory page that the background application is using can be quickly and accurately found through the background memory page identifier. By adjusting the priority of the background memory page corresponding to the background memory page identifier, the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page. By increasing the priority of the foreground memory page, the foreground application obtains a higher memory usage priority and the background application obtains a lower memory usage priority, which can reduce the memory demand of the background application and improve the memory response of the foreground application.

In one embodiment, the adjustment module 606 is also used to: obtain the background memory page identifier corresponding to the background application in the memory page identifier set, determine the linked list where the background memory page corresponding to the background memory page identifier is located; when the background memory page is in the active linked list, move the background memory page to the inactive linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

In this embodiment, the priority of the active linked list is higher than that of the inactive linked list. For the background memory page in the active linked list, the background memory page is moved to the inactive linked list, and the background memory page can be moved to a queue that is not frequently accessed, thereby reducing the priority of the background application to use memory and speeding up the startup speed of the foreground application.

In one embodiment, the adjustment module 606 is further configured to: when the background memory page is in the inactive linked list, keep the background memory page in the inactive linked list.

In this embodiment, when the background memory page is in the inactive linked list, the background memory page is retained in the inactive linked list to keep the background memory page in a queue that is not frequently accessed, thereby reducing the memory demand of the background application and providing more memory for the foreground application.

In one embodiment, the device further includes: a recycling module. The recycling module is used to determine the clean memory pages in the inactive linked list and recycle the clean memory pages.

In this embodiment, by recycling clean memory pages in the inactive linked list, available memory space can be increased to ensure the normal operation of the application.

In one embodiment, the recycling module is further used to determine dirty memory pages in the inactive linked list and recycle the dirty memory pages.

In one embodiment, the recycling module is also used to determine clean memory pages and dirty memory pages in the inactive linked list, and based on the fact that the priority of clean memory pages is higher than that of dirty memory pages, the clean memory pages and dirty memory pages are recycled in turn.

In one embodiment, the adjustment module 606 is further used to: obtain a first application identifier of a foreground application and a second application identifier of a background application; determine a foreground memory page identifier that matches the first application identifier from a memory page identifier set; and adjust the priority of a foreground memory page corresponding to the foreground memory page identifier;

The adjustment module 606 is further used to: determine the background memory page identifier that matches the second application identifier from the memory page identifier set; and adjust the priority of the background memory page corresponding to the background memory page identifier.

In this embodiment, the application identifier and memory page identifier of the same application program have a corresponding relationship. Then, through the first application identifier of the foreground application and the second application identifier of the background application, the matching foreground memory page identifier and the background memory page identifier can be found from the memory page identifier set, so as to adjust the priority of the foreground memory page corresponding to the foreground memory page identifier and the background memory page corresponding to the background memory page identifier, so as to increase the priority of the foreground memory page and reduce the priority of the background memory page, so that the foreground application obtains a higher memory usage priority and improves the startup speed of the foreground application.

In one embodiment, the device further includes: a configuration module. The configuration module is used to configure an application identifier for the updated application when there is an update to the application; and to configure a memory page identifier corresponding to the application identifier for the memory page of the updated application.

In this embodiment, when there is an update to an application, an application identifier is configured for the updated application, and a unique application identifier can be assigned to each application. A memory page identifier corresponding to the application identifier is configured for the memory page of the updated application, and the memory page corresponding to each application can be accurately determined through the correspondence between the memory page identifier and the application identifier, so that the memory page corresponding to the foreground application and the memory page of the background application can be determined, so as to increase the priority of the memory page corresponding to the foreground application, obtain more memory space for the foreground application, and improve the memory usage efficiency.
