Referring to fig. 3, a flowchart of a task execution method according to an embodiment of the present invention is shown. The specific flow shown in fig. 3 will be described in detail below.

Step S202, when the CPU has cores with different computing power, dividing all the cores into cores with N computing levels according to the computing power;

it should be noted that, according to the design requirement of the smart phone, the CPU of the smart phone may be a different core or the same core. The performance of a core is related to its computational power and power consumption, the stronger the computational power, the better the performance and, correspondingly, the faster the power consumption.

Optionally, whether the cores have different computing capabilities or not may be obtained according to the performance parameters of the cores or according to the types of the CPUs, and then the cores are divided into a plurality of operation levels, it is understood that the value of N is greater than or equal to 2.

Step S204, when the task to be executed exists, determining a target core matched with the priority of the task to be executed in the cores of the N operation levels;

it should be noted that the application installed in the smartphone includes multiple tasks, and the tasks may be prioritized according to the implemented function, or the running time and the running state.

Wherein the priority of the task to be executed represents the computing power requirement of the task to be executed; this priority may be preset or determined at the start-up and run-time of the task.

Optionally, when there is a task to be executed, the priority of the task to be executed is obtained, and a core matched with the task to be executed can be obtained according to the priority and cores of multiple operation levels, which is a target core, where the target core may be one or multiple.

Step S206, binding the task to be executed to a target core for operation;

optionally, the running of the task needs to be supported by a core of the CPU, and after the task to be executed and the target core are determined, the task to be executed and the target core are bound to support the running of the task to be executed.

Through the steps, when the CPU has cores with different computing capacities, all the cores are divided into cores with N computing grades according to the computing capacities; when the task to be executed exists, in the cores of the N operation levels, a target core matched with the priority of the task to be executed is determined, the priority of the task to be executed represents the computing capacity requirement of the task to be executed, and the task to be executed and the target core are bound to realize the running of the task. Therefore, the computing power requirement of the task is matched with the computing power of the CPU core, the CPU resource is reasonably utilized, and the effects of saving the electric energy consumption of the mobile terminal and improving the cruising ability are achieved.

In practical application, different mobile terminals and systems supporting application program operation are not necessarily the same, and the systems of the mobile terminals are an Android system and an iOS system generally. The implementation of these two different systems will be described separately below.

Referring to fig. 4, when the system of the smart phone is the first system, i.e., the Android system, a possible implementation manner is provided for the step S202, and the step S202 includes the following steps:

step S202A-1, acquiring the maximum working frequency of each core in the CPU;

optionally, the core comb amount of the CPU may be read first by calling a function, and then the maximum operating frequency of each core may be obtained by reading a file in the smart phone.

Step S202A-3, when the maximum working frequency of at least two cores meets the rearrangement condition, determining that the CPU has cores with different computing power;

it is to be noted that the maximum operating frequency of the core represents the processing speed of the core. The greater the maximum operating frequency, the faster the processing speed, i.e. the greater the computing power.

The duplicate removal condition represents that the maximum working frequencies of any two cores are not coincident, and it can be understood that the difference between the two maximum working frequencies is large.

Alternatively, the average power of the maximum operating frequencies of all cores may be calculated, and when there is a core whose maximum operating frequency is not equal to the average power, it is determined that the CPU has cores with different computing capabilities.

Step S202A-5, dividing all cores into cores of N operation levels according to the maximum working frequency of each core;

optionally, the maximum operating frequency of all cores may be re-ordered to obtain a re-ordering parameter, and the number of cores into which all cores are divided is determined according to the value of N obtained by the re-ordering parameter.

The following describes the above steps S202A-1 to S202A-5, taking the smartphone a of the Android system as an example.

The smart phone a is installed with an application program, and a function "sysconf (SC _ nprocesors _ CONF)" is called in a development tool of the application program to obtain that the number of cores of the CPU of the smart phone is 4, and the CPU of the smart phone has 4 cores, namely, a core a1, a core a2, a core A3 and a core a 4.

Reading files/systems/devices/system/cpu/cpu [ X ]/cpu freq/cpu info _ max _ freq, respectively substituting 0 to 4 into [ X ], obtaining that the maximum working frequency of the core A1 and the core A2 is 1.8GHz, the maximum working frequency of the core A3 and the core A4 is 1.4GHz, calculating the average power of all cores to be 1.6GHz, meeting the weight-removing condition, and calculating the weight-removing parameter to be 2;

all cores may be divided into 2 levels of cores, i.e., N is 2, core a1 and core a2, whose maximum operating frequencies are greater than the average power, are cores whose operation levels are one level, and core A3 and core a4, whose maximum operating frequencies are less than the average power, are cores whose operation levels are two levels, one level being the highest level and two levels being the lowest level, as shown in table 1.

TABLE 1

Core(s)	Maximum operating frequency (/ GHz)	Operation level
			A1	1.8	First stage
A2	1.8	First stage
			A3	1.4	Second stage
A4	1.4	Second stage

Optionally, the steps are performed on the smartphone B with the Android system, and the smartphone B has 6 cores, namely, core B1, core B2, core B3, core B4, core B5 and core B6; obtaining that the maximum working frequency of the cores B1-B2 is 2.6GHz, the maximum working frequency of the cores B3-B4 is 2.2GHz, the maximum working frequency of the cores B5-B6 is 1.8GHz, calculating the average power of all the cores to be 2.2GHz, meeting the weight removal condition, and calculating the weight removal parameter to be 3; all cores may be divided into 3 operation levels, i.e., N is 3, cores B1 and B2 are cores having an operation level of one level, cores B3 and B4 are cores having an operation level of two levels, cores B5 and B6 are cores having an operation level of three levels, one level is the highest level, and three levels are the lowest levels, as shown in table 2.

TABLE 2

Through the steps, for the mobile terminal of the Android system, the maximum working frequency of each core can be obtained, when the maximum working frequencies of at least two cores meet the duplication elimination condition, namely the maximum working frequencies of any two cores are not coincident, all the cores can be divided into the cores of N operation levels, the cores in the CPU can be reasonably divided according to the calculation capacity, the cores are matched with the Android system, the intrusion to the original system is small, and the stable operation of the mobile terminal is facilitated.

In practical applications, the system of the smartphone may also be a second system, i.e., an iOS system, and it may be determined whether the CPU has a core with different computing capabilities according to the type information of the CPU. Furthermore, the embodiment of the present invention provides a possible implementation manner for the step S202, and please refer to fig. 5, wherein the step S202 will be described in detail below.

Step S202B-1, obtaining a core type corresponding to the type information of the CPU from a pre-stored information table;

the pre-stored information table is pre-stored in an application program development tool. The pre-stored information table comprises the type information of the CPU and the corresponding core type.

Optionally, the core type may be obtained by obtaining the type information of the CPU and pre-storing the information table.

Step S202B-3, when at least two core types exist, determining that the CPU has cores with different computing power;

wherein the core type characterizes the computational power of the core;

alternatively, if the core types are plural, that is, not less than two, the CPU has cores with different computing capabilities.

Step S202B-5, dividing all cores into N operation levels according to different computing capacities;

alternatively, the value of N may be determined according to the number of types of cores, and all cores may be divided into cores of N operation levels.

The above-described step S202B-1 to step S202B-5 will be explained below by taking the smartphone C of the iOS system as an example.

As shown in table 3, a part of the content of a pre-stored information table provided in the embodiment of the present invention is shown.

TABLE 3

ID	Code_name	Cpu_count	Big	Little
					0x67ceee93	HURRICANE	4	2	2
0x67ceee93	HURRICANE	6	3	3

An application program is installed in the smart phone C, and a function ' syscllbyname ' (hw. cpufamily ', & value, & len, NULL,0) is called in a development tool of the application program; ", the ID of the CPU is 0x67ceee93, and the type information of the CPU is HURRICANE; by calling the function "syscllbyname (" hw. ncpu ", & count, & len, NULL, 0); ", the core number of the CPU is 6;

through the pre-stored information table, two types of cores are inquired, namely a Big type and a Little type, N is 2, all the cores can be divided into 2 operation-level cores, the core corresponding to the Big type is the core with the first operation level, the core corresponding to the Little type is the core with the second operation level, the first operation level is the highest operation level, and the second operation level is the lowest operation level. I.e. as shown in table 4.

TABLE 4

Core(s)	Type of core	Operation level
			C1	Big	First stage
C2	Big	First stage
			C3	Big	First stage
C4	Little	Second stage
			C5	Little	Second stage
C6	Little	Second stage

Through the steps, the core type can be determined according to the type information of the CPU aiming at the mobile terminal of the iOS system, when at least two core types exist, the CPU has cores with different computing capabilities, all the cores can be divided into cores with N computing levels, the cores in the CPU are reasonably divided according to the computing capabilities, the cores are matched with the iOS system, the invasion to the original system is small, and the stable operation of the mobile terminal is facilitated.

In practical application, the number of tasks of an application program is multiple, the number of cores of a CPU is multiple, the embodiment of the invention prioritizes the tasks, and calculates the grades of the cores, and provides an implementation mode for determining the cores matched with the tasks according to the priorities of the tasks. Referring to fig. 6, the step S204 will be described.

Step S204-1, when the task to be executed is an interactive task, determining the core with the highest operation level as a target core matched with the priority of the interactive task in the cores with the N operation levels;

the interaction task is a task related to user interaction, and can also be understood as a UI thread, which is a thread supporting an application program to interact with a user, and the priority of the task is high.

Optionally, when the task to be executed is an interactive task, a core with the highest operation level is matched with the task.

Step S204-3, when the task to be executed is a low-frequency task, determining the core with the lowest operation level as a target core matched with the priority of the low-frequency task from the cores with the N operation levels;

the low-frequency task represents the task with the shortest historical running time in the preset time, and the priority of the task is low.

Alternatively, the predetermined time may be a second, a minute, a day, and the like, and the embodiment of the present invention is not limited. For example, 1 day, the historical time of running of the task in 1 day is obtained, and when the task to be executed is the task with the shortest historical time, the operation level matched with the task is the core with the lowest level.

Alternatively, it is also possible to determine whether the task to be performed is a low frequency task by using the frequency.

Step S204-5, when the task to be executed is a low-demand task, determining the core with the lowest operation level as a target core matched with the priority of the low-demand task from the cores with the N operation levels;

alternatively, the tasks may be prioritized in advance according to their computing power requirements. The low-demand task represents the task with the lowest computing power demand in the currently executed tasks. The priority of such tasks is low.

Optionally, when the task to be executed is a task with low computational power requirement, the operation level matched with the task is the lowest-level core.

It is understood that during the running process of the task, the running state of the task may be changed, such as from the foreground running to the background running, in which case, the core matched with the task is the core with the lowest operation level.

The method for running the task will be described below by taking the smartphone B as an example.

The smart phone B is provided with an application program, and the application program comprises three tasks: update detection, data statistics and music playing. According to the computing power requirement, the priority of updating detection can be set to be low in advance, the priority of data statistics is set to be medium, and the priority of music playing is set to be high.

When the task to be executed is music playback, the cores that are determined to match the priority of the update detection are the core B1 and the core B2 whose operation levels are one level, that is, the highest level, and the music playback may be bound to either one of the core B1 and the core B2, or both.

When the task to be executed is data statistics, the cores determined to be matched with the priority of the data statistics are the core B3 and the core B4 with the operation level of two, and the data statistics may be bound to either one of the core B3 and the core B4 or both of them.

When the task to be executed is the update detection, the cores determined to match the priority of the update detection are the core B5 and the core B6 having the operation levels of three levels, that is, the lowest level, and the update detection may be bound to any one of the core B5 and the core B6.

After the task runs for a period of time, if an incoming call exists, the application program is switched to the background running, the states of music playing, data statistics and updating detection are changed, and the three tasks are bound with the core B5 and the core B6 with the three operation levels.

The method for running the task will be described below by taking the smartphone C as an example.

The smart phone C is provided with an application program, and the application program comprises an interactive task and a non-interactive task. The priority of the interactive task can be preset to be the highest, and the interactive task is bound with one or two or three of the core C1, the core C2 and the core C3 with the operation level of one level in operation.

When the task to be executed is a non-interactive task such as a data reporting task, the historical running time of the task within a preset time period such as 1 day can be acquired. If the historical run length is longest among all non-interactive tasks, the priority of the task is high and is bound to one, or two or three, of the core C1, the core C2 and the core C3.

If the historical run time is the shortest of all the non-interactive tasks, the priority of the task is low and is bound to one of the core C4, the core C5 and the core C6.

If the historical operating time is not the longest or the shortest among all the non-interactive tasks, the core can be bound according to the computing power requirement of data statistics.

It can be understood that, in the running process of the task, the running time length changes, the priority of the task changes, the core matched with the task changes, and the core matched with the priority of the task can be redetermined according to the preset time and bound with the core.
