[0025] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0026] An embodiment of the present application provides a terminal control method, which adopts two different control strategies to collaboratively control the task execution devices during task scheduling, which not only quickly responds to the performance requirements of the first task, but also can continuously optimize the system performance for the first task to ensure the efficiency, stability and reliability of task execution.

[0027] The terminals described in this application may include, for example, mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, cameras, etc.

[0028] Figure 1 Schematic diagram of the first process of the terminal control method in the embodiment of the present application. Figure 1 As shown, the method may specifically include:

[0029] Step 101: Determine a target performance parameter corresponding to a first task;

[0030] The first task refers to any task to be scheduled by the terminal, and the first task may specifically be a task to be scheduled, a process, or a thread.

[0031] The target performance parameter corresponding to the first task refers to a state or target performance value that the task execution device expects to achieve or maintain during the execution of the first task. For example, the target performance parameter may include the expected values ​​of one or more physical quantities such as task deadline, frequency, power consumption, voltage, temperature, etc.

[0032] In some embodiments, based on the task type of the first task, a target performance parameter corresponding to the first task is determined from a first parameter library, and the first parameter library includes a correspondence between one or more task types and target performance parameters.

[0033] Exemplarily, when a first event is monitored to occur, a trigger signal is generated; in response to the trigger signal, a task type of one or more tasks corresponding to the first event is determined, and the one or more tasks include the first task; based on the task type of the first task, a target performance parameter corresponding to the first task is determined from a first parameter library, and the first parameter library includes a correspondence between one or more task types and the target performance parameter.

[0034] A first event refers to a specific thing or behavior that occurs at a specific time and under specific conditions. The first event is a specific situation or action that can be recognized and responded to by a system or program. An embodiment of the present application provides an event-driven terminal control method. When the first event occurs, one or more tasks corresponding to the first event will be triggered to execute.

[0035] The first event may be a specific event or behavior of a preset application. For example, the first event of the application may be identified by monitoring the running state of the application.

[0036] In some embodiments, the method further includes: configuring a first parameter library based on a device type of the terminal and performance requirements of different task types.

[0037] It should be noted that the software and hardware configurations of different device types are different, that is, the system performance provided is different, and the performance requirements of different task types are also different. The embodiment of the present application flexibly configures the first parameter library according to the device type of the terminal and the performance requirements of different task types, and provides corresponding target performance parameters for different task types of the current terminal.

[0038] Step 102: Controlling a task execution device of the terminal based on a first control strategy to execute a first task;

[0039] The first control strategy is specifically used to adjust the control parameters of the control task execution device so that the performance of the task execution device in the process of executing the first task meets the performance requirements of the first task.

[0040] The task execution device includes one or more devices in the terminal for executing the first task. Exemplarily, the task execution device includes at least one of the following: a central processing unit (CPU), a graphics processing unit (GPU), a neural network processor (NPU), a memory controller, a bus system, etc.

[0041] Accordingly, the control parameters of the central processing unit include at least one of the following: frequency, number of cores, temperature, power consumption, etc. The control parameters of the graphics processing unit include at least one of the following: frequency, power consumption, selection of image processing algorithm, etc. The control parameters of the neural network processor include at least one of the following: frequency, power consumption, weight setting, number of iterations, learning rate, etc. The control parameters of the memory controller include at least one of the following: frequency, memory capacity, memory access speed, etc. The control parameters of the bus system include at least one of the following: frequency, bus width, bus protocol, etc.

[0042] Step 103: During the execution of the first task, obtain the current performance parameter corresponding to the first task;

[0043] The current performance parameter refers to a state or performance value actually reached or maintained by the task execution device during the execution of the first task. By way of example, the current performance parameter may include the actual value of one or more physical quantities such as task execution time, frequency, power consumption, voltage, temperature, etc.

[0044] Step 104: When the error value between the target performance parameter and the current performance parameter is greater than a preset threshold, the task execution device is controlled based on a second control strategy to execute the first task, and the first control strategy and the second control strategy are different.

[0045] The error value (Error) represents the deviation between the actual performance parameters of the first task and the set target performance parameters. When the error value is greater than the preset threshold, it indicates that the control result of the first control strategy does not meet expectations, and the second control parameters need to be called for collaborative control to reduce the deviation between the actual performance parameters of the first task and the set target performance parameters to achieve the best control effect.

[0046] The target performance parameter and the current performance parameter include one or more parameters, and correspondingly, the error value includes one or more error values, or the error value is a weighted value of multiple error values.

[0047] In some embodiments, when the error value between the target performance parameter and the current performance parameter is less than or equal to a preset threshold, it indicates that the best control effect has been achieved, and there is no need to rely on the second control strategy.

[0048] In some embodiments, after the task execution device is controlled based on the second control strategy to execute the first task, the method further includes: controlling the task execution device of the terminal based on the first control strategy to execute the first task. It can be understood that the first control strategy can be the main control strategy, and the second control strategy can be the secondary control strategy, and the second control strategy is used to assist and correct the first control strategy to improve the overall performance of the system.

[0049] In some embodiments, the first control strategy is an open-loop control strategy, and the second control strategy is a closed-loop control strategy. The open-loop control strategy can quickly respond to the performance requirements of the first task, and the closed-loop control strategy continuously optimizes system performance for the first task to ensure control accuracy and stability.

[0050] Exemplarily, the first control strategy may include: based on the task type of the first task, determining a first control parameter corresponding to the first task from a second parameter library, the second parameter library including a correspondence between one or more task types and control parameters; adjusting the control parameter of the task execution device to the first control parameter to execute the first task.

[0051] In some embodiments, the method further comprises: configuring a second parameter library based on the device type of the terminal and the performance requirements of different task types. The embodiment of the present application flexibly configures the second parameter library according to the device type of the terminal and the performance requirements of different task types to provide corresponding control parameters for different task types of the current terminal.

[0052] The second control strategy may include: determining the second control parameter corresponding to the first task using a closed-loop control algorithm based on the error value between the target performance parameter and the current performance parameter; adjusting the control parameter of the task execution device to the second control parameter to execute the first task; obtaining the current performance parameter corresponding to the first task during the execution of the first task; and updating the second control parameter using a closed-loop control algorithm based on the error value between the target performance parameter and the current performance parameter when the error value between the target performance parameter and the current performance parameter is greater than a preset threshold, until the error value between the target performance parameter and the current performance parameter is less than or equal to the preset threshold, or the first task is completed.

[0053] A closed-loop control algorithm is a control method that performs corrections based on the output feedback of the control object. In some embodiments, the closed-loop control algorithm is a proportional-integral-differential algorithm (PID algorithm), which continuously adjusts the control parameters of the task execution device so that the actual performance parameters of the first task are close to the target performance parameters, thereby achieving stable and accurate automatic control. In some embodiments, the closed-loop control algorithm can also be a fuzzy control algorithm, a neural network control algorithm, etc.

[0054] In some embodiments, the first control strategy is a closed-loop control strategy, and the second control strategy is an open-loop control strategy. The closed-loop control strategy can achieve precise control for different task types and continuously optimize system performance, while the open-loop control strategy can quickly respond to the performance requirements of the first task. When the closed-loop control strategy cannot achieve the desired state, the response speed is accelerated by calling the open-loop control strategy.

[0055] Exemplarily, the first control strategy may include: initializing a first control parameter corresponding to the first task based on the task type of the first task; adjusting the control parameter of the task execution device to the first control parameter to execute the first task; obtaining the current performance parameter corresponding to the first task during the execution of the first task; when the error value between the target performance parameter and the current performance parameter is greater than a preset threshold and the switching condition is not met, using a closed-loop control algorithm to update the first control parameter according to the error value between the target performance parameter and the current performance parameter until the error value between the target performance parameter and the current performance parameter is less than or equal to the preset threshold, or the first task is completed; when the error value between the target performance parameter and the current performance parameter is greater than the preset threshold and the switching condition is met, controlling the task execution device based on the second control strategy to execute the first task.

[0056] The switching condition may include that the task progress is less than the target progress; or the number of control cycles is greater than the target number of cycles. That is, if the control effect based on the closed-loop control strategy is poor, switch to the second control strategy to improve the control effect.

[0057] The second control strategy may include: based on the task type of the first task, determining the second control parameter corresponding to the first task from a second parameter library, the second parameter library including the correspondence between one or more task types and control parameters; adjusting the control parameter of the task execution device to the second control parameter to execute the first task.

[0058] In some embodiments, the first control strategy and the second control strategy are different open-loop control strategies, or the first control strategy and the second control strategy are different closed-loop control strategies.

[0059] By adopting the above technical solution, during task scheduling, two different control strategies are used to collaboratively control the task execution devices, which not only quickly responds to the performance requirements of the first task, but also continuously optimizes the system performance for the first task to ensure the efficiency, stability and reliability of task execution.

[0060] In order to better reflect the purpose of the present application, based on the above embodiments of the present application, taking the first control strategy as an open-loop control strategy and the second control strategy as a closed-loop control strategy as an example, further examples are given. Figure 2 As shown, the method specifically includes:

[0061] Step 201: event monitoring;

[0062] Specifically, when the occurrence of a first event is monitored, a trigger signal is generated; in response to the trigger signal, the task type of one or more tasks corresponding to the first event is determined, and the one or more tasks include the first task; based on the task type of the first task, the target performance parameters corresponding to the first task are determined from a first parameter library, and the first parameter library includes a correspondence between one or more task types and the target performance parameters.

[0063] Step 202: open loop control;

[0064] The task execution device of the terminal is controlled based on an open-loop control strategy to execute a first task. Exemplarily, based on the task type of the first task, a first control parameter corresponding to the first task is determined from a second parameter library, the second parameter library including a correspondence between one or more task types and control parameters; the control parameter of the task execution device is adjusted to the first control parameter to execute the first task.

[0065] Based on the open-loop control strategy, when an event occurs, the control parameters can be quickly adjusted according to the task type, so that the actual performance parameters of the first task are close to the target performance parameters.

[0066] Step 203: Error monitoring;

[0067] Specifically, during the execution of the first task, the current performance parameters corresponding to the first task are obtained, and the error value between the target performance parameters and the current performance parameters is determined. The error value is used as a basis for whether to switch to a closed-loop control strategy. Furthermore, the closed-loop control strategy further continuously adjusts the control parameters of the task execution device based on the current error value and the target performance parameters.

[0068] More specifically, according to the sampling period corresponding to the task type, the current performance parameter corresponding to the first task is obtained.

[0069] Step 204: Closed-loop control.

[0070] The task execution device of the terminal is controlled based on a closed-loop control strategy to execute the first task. Exemplarily, when the error value between the target performance parameter and the current performance parameter is greater than a preset threshold, a closed-loop control algorithm is used to determine the second control parameter corresponding to the first task according to the error value between the target performance parameter and the current performance parameter; the control parameter of the task execution device is adjusted to the second control parameter to execute the first task; step 203 is continued to be performed to perform error monitoring to determine the error value between the target performance parameter and the current performance parameter; when the error value between the target performance parameter and the current performance parameter is greater than a preset threshold, the closed-loop control is continued until the error value between the target performance parameter and the current performance parameter is less than or equal to the preset threshold, or the first task is completed.

[0071] Adopt closed-loop control strategy to continuously optimize system performance and ensure control accuracy and stability.

[0072] If the first task is a task with a deadline, and the task execution device is a CPU, the control method may specifically include:

[0073] Event monitoring can specifically include:

[0074] Step a: The event detection module monitors the running state of the application program and identifies the occurrence of a first event (eg, an application startup event, a touch event, an interface refresh event, etc.).

[0075] Step b: When the occurrence of the first event is detected, an event trigger signal is sent to the task scheduling module;

[0076] Step c: The task scheduling module receives the event trigger signal and determines the task type of one or more tasks corresponding to the first event;

[0077] Step d: The task scheduling module determines the deadline (corresponding to the target performance parameter) corresponding to the task type from the preset first parameter library according to the task type. The deadline of the task is the specific embodiment of the system performance requirement in the time dimension. The deadline of the task is used to control the task execution device, which can ensure that the task obtains sufficient resources and is executed before the deadline.

[0078] The deadline of the task is set according to different application scenarios to ensure the timeliness and effectiveness of frequency adjustment. For example, for game, video and browser applications, there are different requirements for the frequency of interface refresh and the response time of touch events.

[0079] Open-loop control can specifically include:

[0080] Step a: According to the task type, extract the corresponding open-loop control parameters (corresponding to the first control parameters) from the preset second parameter library.

[0081] Step b: The open-loop control module uses the extracted open-loop control parameters to adjust the CPU frequency so that the CPU performance is close to the performance requirements of the current task.

[0082] Step c: If the task cannot be completed within the deadline after the open-loop control, the closed-loop control module is called to perform closed-loop control.

[0083] For example, for an application startup task, the deadline is 100ms. The CPU frequency is adjusted through the open-loop control module so that the application startup is completed within 100ms. If it is not completed within 100ms, the closed-loop control is triggered. For another example, for an interface refresh, the deadline is 15ms. The CPU frequency is adjusted through the open-loop control module. If it is not completed within 15ms, the closed-loop control is triggered.

[0084] Closed-loop control can specifically include:

[0085] Step a: The closed-loop control module (such as a PID controller) obtains the target performance parameters and error values ​​corresponding to the current task.

[0086] Step b: The PID control algorithm calculates the adjustment amount of the CPU frequency according to the target performance parameter and the error value, and continuously adjusts the CPU frequency to reduce the error value until the task is completed or the deadline is reached.

[0087] In order to better reflect the purpose of the present application, based on the above embodiments of the present application, taking the first control strategy as a closed-loop control strategy and the second control strategy as an open-loop control strategy as an example, further examples are given. Figure 3 As shown, the method specifically includes:

[0088] Step 301: event monitoring;

[0089] Specifically, when the occurrence of a first event is monitored, a trigger signal is generated; in response to the trigger signal, the task type of one or more tasks corresponding to the first event is determined, and the one or more tasks include the first task; based on the task type of the first task, the target performance parameters corresponding to the first task are determined from a first parameter library, and the first parameter library includes a correspondence between one or more task types and the target performance parameters.

[0090] Step 302: closed loop control;

[0091] Specifically, based on the task type of the first task, the first control parameter corresponding to the first task is initialized; the control parameter of the task execution device is adjusted to the first control parameter to execute the first task; during the execution of the first task, the current performance parameter corresponding to the first task is obtained; when the error value between the target performance parameter and the current performance parameter is greater than a preset threshold and the switching condition is not met, according to the error value between the target performance parameter and the current performance parameter, a closed-loop control algorithm is used to update the first control parameter until the error value between the target performance parameter and the current performance parameter is less than or equal to the preset threshold, or the first task is completed; when the error value between the target performance parameter and the current performance parameter is greater than the preset threshold and the switching condition is met, the task execution device is controlled based on the second control strategy to execute the first task.

[0092] For example, based on the task type of the first task, a first control parameter corresponding to the first task is determined from a third parameter library, and the third parameter library includes initial control parameters corresponding to one or more task type closed-loop control strategies.

[0093] Step 303: Error monitoring;

[0094] Specifically, during the execution of the first task, the current performance parameters corresponding to the first task are obtained, and the error value between the target performance parameters and the current performance parameters is determined. The error value is used as the basis for the closed-loop control of the next cycle and whether to switch to the closed-loop control strategy.

[0095] In some embodiments, if the error value is greater than a preset threshold and the task progress is lower than the target progress, a closed-loop control module is called to perform closed-loop control.

[0096] Step 304: Open loop control.

[0097] The task execution device of the terminal is controlled based on an open-loop control strategy to execute a first task. Specifically, based on the task type and / or error value of the first task, a second control parameter corresponding to the first task is determined; and the control parameter of the task execution device is adjusted to the second control parameter to execute the first task.

[0098] If the first task is a task with a deadline, and the task execution device is a CPU, the control method may specifically include:

[0099] Event monitoring can specifically include:

[0100] Step a: The event detection module monitors the running state of the application program and identifies the occurrence of a first event (eg, an application startup event, a touch event, an interface refresh event, etc.).

[0101] Step b: When the occurrence of the first event is detected, an event trigger signal is sent to the task scheduling module;

[0102] Step c: The task scheduling module receives the event trigger signal and determines the task type of one or more tasks corresponding to the first event;

[0103] Step d: The task scheduling module determines the deadline (corresponding to the target performance parameter) corresponding to the task type from a preset first parameter library according to the task type.

[0104] The deadline of the task is set according to different application scenarios to ensure the timeliness and effectiveness of frequency adjustment. For example, for game, video and browser applications, there are different requirements for the frequency of interface refresh and the response time of touch events.

[0105] Closed-loop control can specifically include:

[0106] Step a: The closed-loop control module (such as a PID controller) obtains the target performance parameters and error values ​​corresponding to the current task.

[0107] Step b: The PID control algorithm calculates the adjustment amount of the CPU frequency according to the target performance parameter and the error value, and continuously adjusts the CPU frequency to reduce the error value until the task is completed or the open-loop control strategy is called.

[0108] For example, for an application startup task, the deadline is 100ms. The CPU frequency is adjusted through the closed-loop control module so that the application startup is completed within 100ms. If it is not completed within 100ms and the switching conditions are met, the open-loop control is triggered. For another example, for an interface refresh, the deadline is 15ms. The CPU frequency is adjusted through the closed-loop control module. If it is not completed within 15ms and the switching conditions are met, the open-loop control is triggered.

[0109] Open-loop control can specifically include:

[0110] Step a: extracting corresponding open-loop control parameters (corresponding to the second control parameters) according to the task type and / or error value.

[0111] Step b: The open-loop control module uses the extracted open-loop control parameters to adjust the CPU frequency so that the CPU performance is close to the performance requirements of the current task.

[0112] In some embodiments, after the open-loop control, the closed-loop control strategy may continue to be called to continuously optimize the system performance for the first task.

[0113] The above technical solution has the following beneficial effects:

[0114] Reduce maintenance costs. By dynamically adjusting parameters, the reliance on static tables is reduced, thus reducing maintenance costs.

[0115] Improve system performance, combine open-loop and closed-loop control, achieve fast response and continuous optimization, and improve the overall system performance.

[0116] Enhanced robustness: PID closed-loop control provides better robustness and can maintain stable performance in a variety of scenarios.

[0117] Improve adaptability and be able to adaptively adjust CPU frequency according to different application scenarios to meet various performance requirements.
