Detailed Description
The technical scheme provided by the embodiment of the application can be applied to various scenes needing data communication, and the embodiment of the application is not limited to the scenes.
Referring to fig. 1, the present application provides a processor temperature control method, a processor temperature control device, a storage medium and an electronic apparatus. The execution body of the processor temperature control method may be a processor temperature control device provided in the embodiment of the present application, or an electronic device integrated with the processor temperature control device, where the processor temperature control device may be implemented in a hardware or software manner. The electronic device may be a device with a processing capability, such as a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer, configured with a processor.
Referring to fig. 1, fig. 1 is a schematic flow chart of a processor temperature control method according to an embodiment of the present application, and a specific flow chart of the processor temperature control method according to an embodiment of the present application may be as follows:
in 110, when the current temperature of the first processor does not reach the preset temperature, current operation information of the first processor is obtained.
It should be noted that the electronic device is generally configured with a plurality of processors, such as a general-purpose central processing unit, a dedicated image signal processor, a front image signal processor, or a graphic processor, or the like. In this embodiment of the present application, the processor that needs to perform temperature control is referred to as a first processor, and the first processor may be configured in any one of the electronic devices. For example, when temperature control is required for the central processor of the electronic device, the central processor of the electronic device is configured as the first processor.
It will be appreciated that in order to control the temperature of the first processor, the temperature of the first processor is known. Accordingly, in the embodiment of the application, the electronic device detects the current temperature of the first processor. It should be noted that, currently, a certain time is not specified, but refers to an execution time when the electronic device performs the temperature detection operation.
However, the embodiment of the present application is not limited to specific limitation, and may be configured by one of ordinary skill in the art according to actual needs.
For example, when a temperature sensor is preset in the first processor, the electronic device may directly read the sensed temperature of the temperature sensor, and use the read sensed temperature as the current temperature of the first processor.
When a plurality of temperature sensors are preset at different positions inside the first processor (shown in fig. 2, three temperature sensors are preset at different positions inside the first processor, namely, a temperature sensor 1, a temperature sensor 2 and a temperature sensor 3 respectively), the electronic device can read the sensing temperatures of the plurality of temperature sensors, and then fit the sensing temperatures to the current temperature of the first processor. The embodiment of the present application is not specifically limited, and may be configured by one of ordinary skill in the art according to actual needs, as to how to fit the plurality of sensed temperatures to the current temperature of the first processor. For example, an average temperature of the plurality of sensing temperatures may be directly obtained, and the average temperature is taken as the current temperature of the first processor; for another example, a corresponding weight may be allocated to each temperature sensor according to the different setting positions of each temperature sensor, and then a weighted sum may be performed according to the weight corresponding to each sensing temperature, so as to obtain a weighted sum value as the current temperature of the first processor.
It should be noted that different processors have different resistance to high temperatures, for example, some processors still operate normally at 75 degrees celsius, while some processors do not operate normally at 60 degrees celsius. Therefore, in the embodiment of the application, for different processors, preset temperatures corresponding to the different processors are preset, and for a processor, when the temperature of the processor exceeds the preset temperature corresponding to the processor, the processor has a high probability of failing to work normally. For a processor, the preset temperature of the processor may be an empirical value obtained by one of ordinary skill in the art. For example, for a processor that cannot operate normally when the temperature exceeds 75 degrees celsius, the preset temperature corresponding to the processor may be configured to be 75 degrees celsius; for another example, if the processor cannot normally operate when the temperature exceeds 60 degrees celsius, the preset temperature corresponding to the processor may be configured to be 60 degrees celsius.
As above, after detecting the current temperature of the first processor, the electronic device further identifies whether the current temperature reaches the preset temperature corresponding to the first processor. And if so, acquiring the current running information of the first processor.
The temperature rise of the first processor is used as constraint, and the operation information required to be acquired can be configured according to actual needs by one of ordinary skill in the art. For example, the current load value, the operating voltage, the operating frequency, etc. of the first processor may be obtained.
In 120, a subsequent warming rate of the first processor is predicted based on the current operating information to obtain a subsequent warming rate.
As described above, in the embodiment of the present application, the obtained current operation information of the first processor and the temperature rise of the first processor are associated to a certain extent, so the electronic device may predict a subsequent temperature rise rate of the first processor according to the obtained current operation information of the first processor, and record the predicted temperature rise rate as the subsequent temperature rise rate.
The subsequent temperature rise rate can be understood in a popular manner as the temperature rise rate of the first processor after the current time.
At 130, the first processor is temperature controlled according to a subsequent temperature ramp rate.
After predicting the subsequent temperature rising rate of the first processor, the electronic device controls the temperature of the first processor according to the predicted subsequent temperature rising rate so as to prevent the temperature of the first processor from reaching a preset temperature, thereby ensuring that the first processor can always be in a normal working state. For example, referring to fig. 3, a temperature rise curve before and after temperature control of the first processor is shown, wherein a vertical axis T represents temperature, a horizontal axis T represents time, a temperature rise curve 1 is a temperature rise curve before temperature control of the first processor, and a temperature rise curve 2 is a temperature rise curve after temperature control of the first processor. It can be seen that after the temperature control of the first processor, the temperature rising rate of the first processor is significantly suppressed, and the maximum temperature that the first processor can reach is far lower than the maximum temperature that can be reached before the temperature control is performed.
It should be noted that, how to perform temperature control on the first processor is not specifically limited in the embodiments of the present application, and may be configured by those of ordinary skill in the art as needed. For example, the operating frequency of the first processor may be reduced, the operating voltage of the first processor may be reduced, and so on.
As can be seen from the above, the present application records the processor needing to perform temperature control as the first processor, and when the current temperature of the first processor does not reach the preset temperature, obtains the current operation information of the first processor, predicts the subsequent temperature rising rate of the first processor according to the current operation information, and obtains the subsequent temperature rising rate, so that the temperature of the first processor is controlled according to the predicted subsequent temperature rising rate, and the temperature of the first processor is prevented from reaching the preset temperature. Compared with the prior art, the temperature control is performed after the temperature of the processor reaches the higher temperature, and the temperature control is performed in advance when the temperature of the processor does not reach the higher temperature, so that the effective temperature control of the processor can be realized.
Optionally, in an embodiment, the temperature controlling of the first processor according to the subsequent temperature ramp rate includes:
(1) Acquiring a first residual duration of the first processor executing the current task;
(2) Predicting a second residual duration of the temperature of the first processor reaching a preset temperature according to the current temperature and the subsequent temperature rise rate;
(3) And when the first residual time period is longer than the second residual time period, performing temperature control on the first processor.
The current task may be any type of processing task, for example, when the first processor is a central processor of the electronic device, the current task executed by the first processor may be various types of application programs running in front of the first processor, when the first processor is a coprocessor of the central processor, the current task executed by the first processor may be any co-processing task allocated to the first processor by the central processor (for example, when the first processor is an image signal processor in the electronic device, the image signal processor will perform image processing in cooperation with the central processor when the central processor runs a camera application, and at this time, the current task executed by the image signal processor is an executed image processing task).
The first processor is exemplified as a central processor.
The electronic equipment firstly obtains the residual time length of the first processor executing the current task and records the residual time length as a first residual time length.
For example, when the first processor runs the video playing application in the current foreground, the video playing application is the current task executed by the first processor, at this time, the electronic device may further obtain the remaining playing duration of the video playing application as the first remaining duration of the first processor executing the current task.
For another example, when the first processor runs the camera application in the current foreground, the camera application is the current task executed by the first processor, at this time, the electronic device may further predict, according to the historical running record of the camera application, the running duration of the camera application (for example, take an average value of the historical running durations), and then subtract the running duration of the camera application from the running duration to obtain the remaining running duration of the camera application at this time, which is used as the first remaining duration of the first processor for executing the current task.
For another example, when the first processor runs the game application in the current foreground, the game application is the current task executed by the first processor, at this time, the electronic device may further predict, according to the historical running record of the game application, the running duration of the game application (for example, take an average value of the historical running durations), and then subtract the running duration of the game application from the running duration to obtain the remaining running duration of the game application at this time, where the remaining running duration is used as the first remaining duration of the first processor for executing the current task.
As above, after obtaining the first remaining duration of the first processor for executing the current task, the electronic device further predicts, according to the current temperature and the subsequent temperature rise rate, a remaining duration of the temperature of the first processor reaching the preset temperature, denoted as a second remaining duration, and may be expressed as:
t＝(Tp-Tn)/S；
where t represents a second remaining time period, tp represents a preset temperature, tn represents a current temperature of the first processor, and S represents a predicted subsequent rate of rise in temperature.
After obtaining the first remaining duration of the first processor for executing the current task and predicting the second remaining duration of the first processor for reaching the preset temperature, the electronic device further identifies whether the first remaining duration is greater than the second remaining duration, and according to the above related description, it can be understood that if the first remaining duration is greater than the second remaining duration, it indicates that the temperature of the first processor has reached the preset temperature when the current task has not been executed, thereby affecting the execution of the current task. Therefore, in order to ensure normal execution of the current task, in the embodiment of the present application, when the electronic device determines that the first remaining time period is longer than the second remaining time period, the electronic device performs temperature control on the first processor, so as to inhibit the temperature rise of the first processor in advance.
Optionally, in an embodiment, the temperature controlling the first processor includes:
(1) Determining a target temperature control strategy corresponding to the task type of the current task according to a first preset corresponding relation between the temperature control strategy and the task type;
(2) A target temperature control strategy is executed to control the temperature of the first processor.
It should be noted that, for different types of tasks, the present application specifically configures a temperature control policy adapted to each type of task, so as to form a corresponding relationship between the temperature control policy and the task type, and record the corresponding relationship as a first preset corresponding relationship. For example, it is assumed that all tasks of the electronic device are classified into four types, namely, a type-a task, a type-B task, a type-C task and a type-D task, so that a corresponding temperature control policy 1 can be allocated to the type-a task, a corresponding temperature control policy 2 can be allocated to the type-B task, a corresponding temperature control policy 3 can be allocated to the type-C task, and a corresponding temperature control policy 4 can be allocated to the type-D task.
Accordingly, in the embodiment of the present application, when the electronic device performs temperature control on the first processor, the temperature control policy corresponding to the task type of the current task executed by the first processor is determined according to the first preset correspondence between the temperature control policy and the task type, and is recorded as the target temperature control policy.
And then, the electronic equipment executes the determined target temperature control strategy to realize temperature control of the first processor.
The first processor is exemplified as a central processor. For camera applications, the configured temperature control strategy includes a plurality of gear positions:
gear 1: reducing the brightness of the screen;
gear 2: removing other applications of the background which are not related to the camera application;
gear 3: reducing the screen display resolution;
gear 4: reducing the image frame rate of the image sensor;
gear 5: some unnecessary image optimization algorithms, such as a beauty algorithm, etc., are turned off.
Assuming that the current task executed by the first processor is a camera application, when temperature control is performed for the first time, performing temperature control according to the gear 1, namely reducing screen brightness, and if temperature control is still required after the first control, performing temperature control again according to the gear 2, namely removing other applications of the background which are not related to the camera application. And so on, gradually increasing the gear of the temperature control until the residual duration of the first processor executing the current task is less than or equal to the residual duration of the temperature of the first processor reaching the preset temperature.
Optionally, in an embodiment, the target temperature control strategy is executed independently of execution of the current task by the first processor.
It should be noted that, in the embodiment of the present application, the execution of the temperature control policy does not affect the execution of the current task by the first processor, and the configuration of the temperature control policy may be performed by one of ordinary skill in the art according to actual needs.
Accordingly, when the electronic device executes the target temperature control strategy, the execution of the target temperature control strategy does not affect the execution of the current task by the first processor, so that the execution of the current task by the first processor is not affected. For example, assuming that the first processor is a central processor, the current task executed by the first processor is a game application, and the electronic device does not cause a deterioration of the running effect of the game application, such as a click or the like, when executing the target temperature control strategy.
Optionally, in an embodiment, the current operation information includes a current load value, an operating frequency, and an operating voltage of the first processor, and executing the target temperature control policy to perform temperature control on the first processor includes:
(1) Executing a target temperature control strategy to reduce a load value of the first processor;
(2) And reducing the working frequency and/or the working voltage of the first processor according to the reduced load value.
It should be noted that the load value is from the task scheduling point of view, for example, for the first processor, the load value is 100% if a percentage of 1 second is occupied by the task (i.e., no idle time), the load is 50% if only 0.5 second is occupied by the task and the other 0.5 second is idle.
In this embodiment of the present application, the temperature control policy is configured to reduce the load value of the first processor, and with this as a constraint, the configuration of the temperature control policy may be performed by those skilled in the art according to actual needs. The execution of the temperature control policy may affect the execution of the current task, or may not affect the execution of the current task.
The first processor is exemplified as a central processor. For gaming applications, the configured temperature control strategy includes a plurality of gear positions:
gear 1: reducing the brightness of the screen;
gear 2: removing other applications of the background which are not related to the game application;
gear 3: reducing the screen display resolution;
gear 4: reducing some effects of the game application, such as reducing plant effects, reducing water effects, etc.
Gear 5: some special effects of the game application are turned off.
When the current task executed by the first processor is a game application, the temperature control is performed according to the gear 1 for the first time, namely, the screen brightness is reduced, and if the temperature control is still required after the first control, the temperature control is performed again according to the gear 2, namely, other applications of which the background is irrelevant to the game application are cleared. And so on, gradually increasing the gear of the temperature control until the residual duration of the first processor executing the current task is less than or equal to the residual duration of the temperature of the first processor reaching the preset temperature.
In the embodiment of the application, the load value of the first processor is reduced by executing the target temperature control strategy. When the load value of the first processor is reduced, the temperature rising rate of the first processor is correspondingly reduced.
In order to further enhance the effect of temperature control, after the load value of the first processor is reduced, the electronic device further reduces the operating frequency and/or the operating voltage of the first processor according to the reduced load value, thereby further reducing the temperature rising rate of the first processor. The electronic device may reduce the operating frequency of the first processor only, reduce the operating voltage of the first processor only, or reduce both the operating frequency and the operating voltage of the first processor.
For example, a corresponding relationship between the load value and the operating frequency may be established in advance according to experience, or a corresponding relationship between the load value and the operating voltage may be established, or a corresponding relationship between the load value and the operating frequency and a corresponding relationship between the operating voltage may be established, so that after the load value of the first processor is reduced, the operating frequency and/or the operating voltage of the first processor may be directly reduced to the operating frequency and/or the operating voltage corresponding to the reduced load value according to the foregoing corresponding relationship.
Optionally, in an embodiment, the processor temperature control method provided in the present application further includes:
(1) Loading a second preset corresponding relation between the operation information and the heating rate into a memory;
predicting a subsequent temperature rising rate of the first processor according to the current operation information to obtain the subsequent temperature rising rate, wherein the method comprises the following steps of:
(2) And setting the temperature rising rate corresponding to the current operation information as a subsequent temperature rising rate according to a second preset corresponding relation in the memory.
It should be noted that, in the embodiment of the present application, the historical operation information of the first processor and the heating rate corresponding to the historical operation information are collected in advance, so that the corresponding relationship between the operation information of the first processor and the heating rate is counted and is recorded as the second preset corresponding relationship.
In this embodiment of the present application, the electronic device loads the second preset correspondence between the operation information and the heating rate into the memory in advance, so when predicting the subsequent heating rate of the first processor according to the current operation information of the first processor, the heating rate of the current operation information corresponding to the first processor may be set as the subsequent heating rate of the first processor directly according to the second preset correspondence loaded in the memory.
Optionally, in an embodiment, the second preset correspondence is stored in a lookup table.
In this embodiment, the foregoing second preset correspondence may be stored in a look-up table, for example, please refer to the following table, where the operation information includes a load value, an operating voltage, and an operating frequency as an example:
| load value | Operating voltage | Operating frequency | Rate of temperature rise |
| W1 | V1 | P1 | S1 |
| W2 | V2 | P2 | S2 |
| W3 | V3 | P3 | S3 |
| W4 | V4 | P4 | S4 |
For example, when the current operation information of the first processor is obtained, the load value is W1, the operating voltage is V1, and the operating frequency is P1, then the subsequent temperature rising rate of the first processor is S1.
Optionally, in an embodiment, predicting a subsequent heating rate of the first processor according to the current operation information to obtain the subsequent heating rate includes:
(1) The current operation information is sent to a second processor, so that the second processor inputs the current operation information into a pre-trained temperature rise prediction model to predict, and a subsequent temperature rise rate is obtained;
(2) And receiving a subsequent temperature rise rate returned by the second processor.
It should be noted that, in the embodiment of the present application, a machine learning method is pre-adopted to train a temperature rise prediction model, and the trained temperature rise prediction model is deployed in an electronic device. Among them, machine Learning (ML) is a multi-domain interdisciplinary, and involves multiple disciplines such as probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory, etc. It is specially studied how a computer simulates or implements learning behavior of a human to acquire new knowledge or skills, and reorganizes existing knowledge structures to continuously improve own performance. Machine learning is the core of artificial intelligence, a fundamental approach to letting computers have intelligence, which is applied throughout various areas of artificial intelligence. Machine learning and deep learning typically include techniques such as artificial neural networks, belief networks, reinforcement learning, transfer learning, induction learning, and the like.
Illustratively, training samples are pre-acquired, along with labels corresponding to the training samples. For example, the operation information of the electronic device may be collected, and the candidate heating rate of the electronic device under the operation information may be obtained through the related temperature measurement device, then the operation information is used as a training sample, and the heating rate is used as a label corresponding to the training sample. In this manner, a plurality of training samples and corresponding labels may be obtained.
And performing supervised model training by using the acquired training samples and the corresponding labels, so as to train to obtain a temperature rise prediction model, wherein the temperature rise prediction model can be used for predicting the candidate temperature rise rate of the electronic equipment according to the operation information of the electronic equipment.
It should be noted that, in the embodiment of the present application, in order not to further increase the operation burden of the first processor, but to be executed by other processors in the electronic device, which have corresponding operation capabilities, in addition to the first processor, the other processors are denoted as second processors.
Correspondingly, when predicting the subsequent temperature rising rate of the first processor according to the current operation information, the electronic device can send the current operation information to the second processor, and the subsequent temperature rising rate of the electronic device is obtained by inputting the current operation information into a pre-trained temperature rising prediction model for prediction, and the subsequent temperature rising rate returned by the second processor is received for temperature control of the first processor. For how to control the temperature of the first processor according to the subsequent temperature rising rate, reference may be made to the related description in the above embodiments, which is not repeated here.
Fig. 4 is another schematic flow chart of a temperature control method of a processor according to an embodiment of the present application. The following description will take, as an example, a case where the main body of execution and the control object of the processor temperature control method are both central processors in electronic devices. As shown in fig. 4, the flow of the processor temperature control method provided in the embodiment of the present application may be as follows:
in 210, the cpu loads the second preset correspondence between the operation information and the heating rate into the memory.
It should be noted that, in the embodiment of the present application, the historical operation information of the central processing unit and the heating rate corresponding to the historical operation information are collected in advance, so that the corresponding relationship between the operation information of the central processing unit and the heating rate is counted and is recorded as the second preset corresponding relationship.
In the embodiment of the application, the central processing unit loads the second preset corresponding relation between the operation information and the heating rate into the memory in advance, and the second preset corresponding relation is used for predicting the heating rate in the follow-up process.
In 220, when the current temperature does not reach the preset temperature, the central processing unit obtains the current running information of the central processing unit.
It should be noted that the electronic device is generally configured with a plurality of processors, such as a general-purpose central processing unit, a dedicated image signal processor, a front image signal processor, or a graphic processor, or the like. In the embodiment of the application, the central processing unit is taken as a temperature control object for illustration.
It will be appreciated that for temperature control of the cpu, the temperature of the cpu is known. Accordingly, in the embodiment of the present application, the cpu detects its current temperature. It should be noted that, the present invention does not refer to a certain time, but refers to an execution time when the cpu executes the temperature detection operation, and may be any time.
However, the embodiment of the present application is not limited to specific limitation, and may be configured by those skilled in the art according to actual needs.
For example, when a temperature sensor is preset in the central processing unit, the central processing unit can directly read the sensing temperature of the temperature sensor, and the read sensing temperature is taken as the current temperature of the central processing unit.
When a plurality of temperature sensors are preset at different positions inside the central processing unit (three temperature sensors are preset at different positions inside the central processing unit, namely, a temperature sensor 1, a temperature sensor 2 and a temperature sensor 3, respectively) are shown in fig. 2, the central processing unit can read the sensing temperatures of the plurality of temperature sensors, and then fit the sensing temperatures to the current temperatures of the central processing unit. The embodiment of the present application is not particularly limited, and may be configured by one of ordinary skill in the art according to actual needs, as to how to fit the plurality of sensing temperatures to the current temperature of the central processing unit. For example, the average temperature of a plurality of sensing temperatures can be directly obtained, and the average temperature is used as the current temperature of the central processing unit; for another example, a corresponding weight may be allocated to each temperature sensor according to the different setting positions of each temperature sensor, and then a weighted sum may be performed according to the weight corresponding to each sensing temperature, so as to obtain a weighted sum value as the current temperature of the central processing unit.
It should be noted that different processors have different resistance to high temperatures, for example, some processors still operate normally at 75 degrees celsius, while some processors do not operate normally at 60 degrees celsius. Therefore, in the embodiment of the application, for different processors, preset temperatures corresponding to the different processors are preset, and for a processor, when the temperature of the processor exceeds the preset temperature corresponding to the processor, the processor has a high probability of failing to work normally. For a processor, the preset temperature of the processor may be an empirical value obtained by one of ordinary skill in the art. For example, for a processor that cannot operate normally when the temperature exceeds 75 degrees celsius, the preset temperature corresponding to the processor may be configured to be 75 degrees celsius; for another example, if the processor cannot normally operate when the temperature exceeds 60 degrees celsius, the preset temperature corresponding to the processor may be configured to be 60 degrees celsius.
As described above, after detecting the current temperature of the cpu, the cpu further identifies whether the current temperature reaches the preset temperature corresponding to itself. If so, acquiring the current running information of the user.
Wherein, the operation information which needs to be acquired can be configured by one of ordinary skill in the art according to actual needs by taking the temperature rise association with the central processing unit as constraint. For example, the current load value, the operating voltage, the operating frequency, etc. of the central processing unit can be obtained.
In 230, the central processor sets the heating rate corresponding to the current operation information to be the subsequent heating rate of the central processor according to the second preset corresponding relation in the memory.
After the central processing unit obtains the current running of the central processing unit, the heating rate of the current running information of the corresponding central processing unit can be set as the subsequent heating rate of the central processing unit directly according to the second preset corresponding relation loaded in the memory.
The second preset corresponding relationship is stored in a lookup table.
The second preset correspondence may be stored in a look-up table, for example, please refer to the following table, where the operation information includes a load value, an operating voltage, and an operating frequency as an example:
| load value | Operating voltage | Operating frequency | Rate of temperature rise |
| W1 | V1 | P1 | S1 |
| W2 | V2 | P2 | S2 |
| W3 | V3 | P3 | S3 |
| W4 | V4 | P4 | S4 |
For example, if the current operation information of the central processing unit is obtained, the load value is W1, the working voltage is V1, and the working frequency is P1, then the subsequent temperature rising rate of the central processing unit is S1.
At 240, the central processor obtains a first remaining duration of foreground application execution.
For example, the central processing unit may further obtain the remaining playing duration of the video playing application when the central processing unit runs the video playing application in the current foreground, and the remaining playing duration may be used as the first remaining duration when the central processing unit runs the video playing application (i.e. the previous application).
For another example, the central processor may further predict, according to the historical running record of the camera application, the running duration of the camera application (for example, taking an average value of the historical running durations), and then subtract the running duration of the camera application from the running duration to obtain the remaining running duration of the camera application at this time, where the remaining running duration is used as the first remaining duration for the central processor to run the camera application (i.e., the foreground application).
For another example, the central processor may further predict, according to the historical running record of the game application, a running duration of the game application (for example, taking an average value of the historical running durations), and then subtract the running duration of the game application from the running duration to obtain a remaining running duration of the game application at this time, where the remaining running duration is used as a first remaining duration for the central processor to run the game application (i.e., the foreground application).
At 250, the central processor predicts a second remaining time period for the temperature to reach the preset temperature based on the current temperature and the subsequent ramp rate.
As above, after the first remaining duration of the central processing unit running the foreground application is obtained, the central processing unit further predicts the remaining duration of the self temperature reaching the preset temperature according to the current temperature and the subsequent temperature rising rate, and marks the remaining duration as a second remaining duration, which can be expressed as:
t＝(Tp-Tn)/S；
wherein t represents a second remaining time period, tp represents a preset temperature, tn represents a current temperature of the central processing unit, and S represents a predicted subsequent temperature rise rate.
In 260, when the first remaining time period is longer than the second remaining time period, the central processing unit determines, according to a first preset correspondence between the temperature control policy and the application type, a target temperature control policy corresponding to the application type of the foreground application.
After the first remaining duration of the running of the foreground application by the central processor is obtained, and the second remaining duration of the running of the foreground application by the central processor is predicted, the central processor further identifies whether the first remaining duration is greater than the second remaining duration, and according to the above related description, it can be understood that if the first remaining duration is greater than the second remaining duration, it is indicated that the temperature of the central processor has reached the preset temperature when the running of the foreground application is not completed, so that the running of the foreground application is affected. Therefore, in order to ensure normal operation of the foreground application, in the embodiment of the present application, when the central processor determines that the first remaining time period is longer than the second remaining time period, the central processor controls the temperature of the central processor, so as to inhibit the temperature of the central processor from rising in advance.
At 270, the central processor executes a target temperature control strategy to temperature control itself.
It should be noted that, for different types of applications, the present application is specifically configured with a temperature control policy adapted to each type of application, so as to form a corresponding relationship between the temperature control policy and the application type, and record the corresponding relationship as a first preset corresponding relationship. For example, it is assumed that all applications of the cpu are classified into four types, namely, a type a application, a type B application, a type C application, and a type D application, so that a corresponding temperature control policy 1 may be allocated to the type a application, a corresponding temperature control policy 2 may be allocated to the type B application, a corresponding temperature control policy 3 may be allocated to the type C application, and a corresponding temperature control policy 4 may be allocated to the type D application.
Accordingly, in the embodiment of the present application, when the central processing unit performs temperature control on the central processing unit, firstly, according to a first preset corresponding relationship between a temperature control policy and an application type, a temperature control policy corresponding to the application type of the current application executed by the central processing unit is determined and recorded as a target temperature control policy.
And then, the central processing unit executes the determined target temperature control strategy to realize temperature control of the central processing unit.
For example, for camera applications, the configured temperature control strategy includes a plurality of gear steps:
gear 1: reducing the brightness of the screen;
gear 2: removing other applications of the background which are not related to the camera application;
gear 3: reducing the screen display resolution;
gear 4: reducing the image frame rate of the image sensor;
gear 5: some unnecessary image optimization algorithms, such as a beauty algorithm, etc., are turned off.
Assuming that a foreground application operated by the central processing unit is a camera application, when temperature control is performed for the first time, performing temperature control according to the gear 1, namely reducing screen brightness, and if temperature control is still required after the first control, performing temperature control again according to the gear 2, namely removing other applications of the background which are not related to the camera application. And by analogy, gradually increasing the temperature control gear until the residual duration of the running of the foreground application by the central processing unit is less than or equal to the residual duration of the preset temperature of the central processing unit.
