Detailed ways

The power consumption of the processor occupies a relatively large proportion in the overall power consumption of the electronic device, so if the power consumption of the processor can be reduced, it will have positive significance for the reduction of the overall power consumption of the device. In the data processing method provided by the embodiment of the present invention, the two processors of the electronic device are usually in a low power consumption state to save power consumption. After receiving the data from the external device, one of the processors judges whether another processor needs to process the data, if not, then continue to maintain the low power consumption state of the other processor, thereby saving the power consumption of the device. Overall power consumption, prolonging the battery life of the device.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The data processing method provided by the embodiment of the present invention is applied to a first electronic device, and the first electronic device may be a terminal device such as a smart phone (Smartphone), a tablet computer (PAD), or the like. The first electronic device includes a first processing unit and a second processing unit. Specifically, the first processing unit may be an application processor for processing additional terminal application functions such as audio/video processing, document processing, and data processing. (AP), the second processor may be a communication processor (or baseband processor BP) for processing the communication protocol stack and realizing the basic call function of the terminal. Two processors can communicate through shared memory.

In the embodiment of the present invention, the first processing unit has a first working state and a second working state, and the second power consumption of the first processing unit in the second working state is greater than that in the first working state First power consumption; the second processing unit has a third working state and a fourth working state, and the fourth power consumption of the second processing unit in the fourth working state is greater than that in the third working state. Three power consumption.

Processors in the prior art are generally capable of providing multiple operating modes, and consume different power consumption in different operating modes. Corresponding to different operating modes of the processor, the processor is in different working states. The processor itself can adapt to different processing tasks by changing the CPU core voltage and/or the bus frequency. For example, by reducing CPU core voltage and/or bus frequency, processor power consumption can be reduced to improve battery life. Here, according to different processors, the first working state and the third working state can be states such as the sleep state/deep sleep state of the processor, and the second working state and the fourth working state can be the normal working state of the processor. state. Usually, the second power consumption is greater than the fourth power consumption.

Please refer to FIG. 1, the data processing method provided by the embodiment of the present invention includes the following steps:

Step 11, when the first processing unit is in the first working state and the second processing unit is in the third working state, the first electronic device receives data from the second electronic device.

Here, the first and second processors of the first electronic device initially work respectively in the first working state and the third working state with lower power consumption, so as to save power consumption of the device. The first electronic device and the second electronic device can communicate through an existing network, such as a mobile communication network, a wireless local area network, and the first electronic device and the second electronic device need to have a module/ components. The second electronic device sends the data to the first electronic device through the network.

Step 12, controlling the second processing unit to enter the fourth working state from the third working state.

Here, after receiving the data, the first electronic device may generate an interrupt, through which the second processing unit is triggered to enter a fourth working state with higher power consumption from the third working state. The second processing unit in the fourth working state can analyze and process the received data.

In step 13, the second processing unit judges whether the data satisfies a preset processing condition, and obtains a processing result.

The second processing unit in the fourth working state can analyze and process the received data. Here, the processing condition is preset according to needs, and is used to determine whether the data needs to be handed over to the first processing unit for further processing.

Step 14, when the processing result shows that the data does not satisfy the preset processing condition, ignore the data and maintain the first processing unit in the first working state.

In the above step 14, the first processor may directly discard the data to ignore the data, and continue to maintain the first processing unit in the first working state, and then immediately control the second processing unit to re-enter the third working state to save its power consumption.

Step 15, when the processing result indicates that the data satisfies the preset processing condition, control the first processing unit to enter the second working state from the first working state; sent to the first processing unit for processing.

It can be seen from the above steps that in the embodiment of the present invention, when the two processors are maintained in the working state of lower power consumption, if the device receives external data, the second processor is controlled to enter the state of higher power consumption to judge Whether the data needs to be further processed by the first processor: if it is not needed, then maintain the first processor in a low power consumption state, so as to avoid the loss of the overall power consumption of the device caused by the first processor entering a high power consumption state increase, thereby saving power consumption of the device. Moreover, in this embodiment, after ignoring the data, the second processor is controlled to immediately enter a low-power consumption whole, which can also further reduce power consumption of the device.

The setting of the processing conditions and the corresponding processing in the embodiment of the present invention are further described below.

In the embodiment of the present invention, the data in the above step 11 is preferably a data service message.

Taking smart phones as an example, with the development of technology, the functions of smart phones are becoming more and more perfect and powerful, almost equivalent to a small computer. One of the most important functions of a smartphone is the ability to surf the Internet like a regular computer. However, on the existing Internet, there are many kinds of junk messages or attack packets. For a PC or laptop, these attack packets are immediately processed by the CPU and discarded. Since these devices usually have an external power supply or a large battery pack, it does not have a significant impact on the power consumption of the device. As for smart phones, on the one hand, their battery capacity is very small, on the other hand, users have higher requirements on battery life, and more importantly, as people's most important portable devices, more and more smart phone applications require always online. Therefore, this also requires the smartphone to maintain a connection to the network even when it is in standby, and to be able to access the Internet at any time, instead of closing the lid and sleeping like a laptop.

The inventor found that when the smart phone is hung on the Internet, due to the attacks of various spam messages, the smart phone usually cannot get sleep well, and it is often woken up by spam messages immediately after sleeping for a while, and the On the other hand, due to the design of the network protocol stack, the operating system will process it according to its normal communication. First, the second processor (BP) will be awakened for processing, and then the first processor (AP) will be awakened to process spam. arts. Every time the operating system wakes up, it will wait for a UserInactivety (user inactive) time, usually about 5 to 7 seconds. Therefore, each such spam attack will cause a current spike of about 10 seconds in total. This means that the average standby current of the mobile phone will increase a lot, which will cause the power of the mobile phone to be exhausted quickly and seriously reduce the battery life.

The inventors found that, for terminal equipment, the services (such as Push Mail, Push News, etc.) that need to be online in real time even when they are dormant have limited and relatively fixed IP addresses, and only source IP addresses are available when the terminal equipment is dormant. The data based on these IP addresses is the valid data (the data that the user cares about). Therefore, in order to ensure that the first processor (AP) of the smart phone can go into sleep normally and minimize the impact of garbage packets, it can The source IP address setting of message corresponds to the processing condition, such as providing user interface, receiving the list of IP addresses allowed to let go set by the user, now above-mentioned step 13 specifically includes:

The source IP address of the data service message is obtained by the second processing unit, specifically, the source IP address can be obtained by parsing the packet header of the received message;

According to whether the source IP address belongs to a predetermined IP address, it is judged whether the data satisfies a preset processing condition: if the source IP address belongs to the predetermined IP address, it is judged that the data satisfies the processing condition; otherwise, then judged as unsatisfactory.

Through the above processing, the terminal device (such as a smart phone) will directly process and discard the junk messages by the second processor (BP), and will not report to the upper layer protocol and the first processor (AP), so there is no need to wake up the second processor (AP). A processor (AP), so it can significantly reduce device power consumption caused by spam attacks and prolong battery life. Moreover, after the second processor (BP) finishes processing, the second processor (BP) can also be controlled to immediately enter a low power consumption state without waiting for UserInactivety (user inactivity) to time out, so as to further save power. Through the above two measures, the inventor found that this embodiment can make the impact of each garbage packet attack very small, and the realization data in a specific environment shows that after applying this embodiment, the average standby current of the terminal decreases from Around 20mA can be reduced to less than 10mA.

The above describes how to set the processing conditions and processing in this embodiment for data service packets. In this embodiment, the processing conditions may also be set in other agreed manners.

For example, a specific identification bit and its value are pre-agreed between electronic devices, and based on the identification bit, it is determined whether the received data comes from an expected legal electronic device, and then it is determined whether the first processor (AP) is required to process the data. deal with. At this time, the above-mentioned step 13 specifically includes:

Obtaining the value of a predetermined identification bit in the data through the second processing unit;

According to whether the numerical value is a predetermined value, it is judged whether the data satisfies a preset processing condition: if the numerical value is the predetermined value, it is judged that the data satisfies the processing condition; otherwise, it is judged as not satisfied.
