[0043] In general, the terminal device shown in FIG. 1 described above needs to be equipped with a corresponding operating system and run based on the operating system. For example, the operating system of the terminal device can be an Android system, an iOS system, a Linux system, etc.

[0044] In the process that the display unit displays the application picture, the processor needs to perform rendering and other processes on the picture to be displayed, and finally complete the display on the display screen. At present, the adjustment of the processor performance in the display process of the terminal device is usually based on the frame rate adjustment of the application program. The terminal device adjusts the performance of the processor according to the frame rate of the currently running application program, and then displays the corresponding application picture. However, the application pictures to be displayed in the process that the terminal device runs an application program are various, and therefore the processor performance after the above adjustment cannot meet the requirements of different interfaces, and problems such as insufficient performance or performance waste are prone to occur.

[0045] In order to solve the problems in the related art, improve the accuracy of the terminal device in adjusting the performance of the processor, and improve the adaptability of the scheme for adjusting the performance of the processor to different application pictures, the present application provides a performance adjustment method, which can compare the picture data of a current frame picture with the picture data of adjacent continuous N frame pictures by acquiring the picture data of the picture, and timely adjust the performance of the processor when it is found that the difference is greater than a preset threshold.

[0046] Please refer to FIG. 2, which shows a method flowchart of a performance adjustment method provided by an example embodiment of the present application, which can be applied to a terminal device. As shown in FIG. 2, the performance adjustment method can include the following steps:

[0047] Step 201: Acquire the picture data of a current frame picture and the picture data of each of N continuous frame pictures adjacent to the current frame picture. The picture data is used to indicate the data amount of rendering a frame picture by the terminal device, and N is a positive integer.

[0048] Optionally, the current frame picture is an application picture currently to be displayed by the terminal device. The N continuous frame pictures adjacent to the current frame picture are N frame pictures that have been displayed by the terminal device before the current frame picture. For example, for the terminal device, in the process of displaying an application picture, each frame of the application picture is displayed in turn. In the display process, the picture data of each frame of the application picture can be recorded. When the performance adjustment of the present scheme needs to be performed, the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture that have been recorded are acquired.

[0049] Optionally, in the present scheme, the picture data can be used to indicate the data amount of rendering a frame picture by the terminal device. For example, if a frame picture is more complex, the data amount of rendering the frame picture by the terminal device is greater. Optionally, the picture data can be the number of layers or the number of brushes. The terminal device can acquire the picture data by setting a corresponding collector to collect and record the picture data.

[0050] Optionally, the N is a positive integer which can be designed by the developer or the user, for example, N = 1, the terminal device can obtain the picture data of the current frame picture and the picture data of the adjacent previous frame picture. If N = 2, the terminal device obtains the picture data of the current frame picture and the picture data of the adjacent previous two frame pictures. Similarly, details are not repeated here.

[0051] In step 202, the target data difference value is obtained according to the picture data of the current frame picture and the picture data of the adjacent continuous N frame pictures, and the target data difference value is the maximum difference between the picture data of the current frame picture and the picture data of each of the N frame pictures.

[0052] Optionally, the terminal device can obtain the target data difference value in the following manner. For example, the terminal device can perform difference operation on the picture data of the current frame picture and the picture data of the continuous N frame pictures in sequence, and obtain the maximum difference value as the target data difference value. Alternatively, the terminal device can also uniformly regard the picture data of the current frame picture and the picture data of the continuous N frame pictures adjacent to the current frame picture as a set, the set contains N+1 picture data, and the maximum difference value is obtained as the target data difference value by performing difference operation on the set in pairs.

[0053] In step 203, when the target data difference value is greater than the preset difference threshold value, the performance strategy of the processor of the terminal device is adjusted according to the picture data of the current frame picture.

[0054] Optionally, the greater the target data difference value, the greater the difference between the current frame picture and the adjacent continuous N frame pictures, and the greater the difference in the amount of data rendered by the terminal device. When the target data difference value is greater than the preset difference threshold value, it means that the amount of data to be rendered by the terminal device has changed greatly, and the terminal device needs to adjust the performance strategy of the processor of the terminal device according to the picture data of the current frame picture, so as to meet the demand of the processor performance for the current frame picture.

[0055] Optionally, different performance strategies correspond to different power consumptions of the processor of the terminal device. When the picture data of the current frame picture is large, the performance of the processor to be used is higher, and when the picture data of the current frame picture is small, the performance of the processor to be used is lower. That is, the greater the picture data of the current frame picture, the more the amount of data rendered by the terminal device, and the higher the demand for the performance of the processor, so the terminal device needs to improve the performance of the processor to bring higher power consumption, and the smaller the picture data of the current frame picture, the less the amount of data rendered by the terminal device, and the lower the demand for the performance of the processor, so the terminal device needs to reduce the performance of the processor to save power consumption.

[0056] In summary, the terminal device acquires the picture data of the current frame picture and the picture data of each of the continuous N frame pictures adjacent to the current frame picture, the picture data is used to indicate the data amount of rendering a frame picture by the terminal device, N is a positive integer; the terminal device acquires a target data difference value according to the picture data of the current frame picture and the picture data of each of the continuous N frame pictures adjacent to the current frame picture, the target data difference value is the maximum difference value between the picture data of the current frame picture and the picture data of each of the N frame pictures; and the terminal device adjusts the performance strategy of the processor of the terminal device according to the picture data of the current frame picture in the case that the target data difference value is greater than a preset difference threshold. The terminal device of the present application can acquire the picture data of a picture, the picture data is used to indicate the data amount of rendering the frame picture, the target data difference value is calculated according to the picture data of the current frame picture and the picture data of each of the continuous N frame pictures adjacent to the current frame picture, in the case that the target data difference value is greater than the preset difference threshold, it is indicated that the data amount of rendering changes greatly, at this time, the terminal device can adjust the performance strategy of the processor according to the picture data of the current frame picture in time, so as to meet the requirement of the current frame picture on the performance of the processor, thereby avoiding the problems of insufficient performance or performance waste, improving the accuracy of the terminal device in adjusting the performance of the processor, and making the scheme of adjusting the performance of the processor more suitable for various application pictures.

[0057] In a possible implementation manner, the terminal device stores different performance strategies corresponding to different data ranges, and the performance strategy of the processor of the terminal device is adjusted based on the data range in which the picture data of the current frame picture is located, thereby improving the accuracy of the terminal device in adjusting the performance of the processor.

[0058] Please refer to FIG. 3, which shows a method flowchart of a performance adjustment method provided by an example embodiment of the present application, and the performance adjustment method can be applied to a terminal device. As shown in FIG. 3, the performance adjustment method can include the following steps:

[0059] In step 301, the picture data of the current frame picture and the picture data of each of the continuous N frame pictures adjacent to the current frame picture are acquired, the picture data is used to indicate the data amount of rendering a frame picture by the terminal device, N is a positive integer.

[0060] Optionally, the current frame picture is an application picture currently required to be displayed by the terminal device. For example, the application picture required to be displayed in the terminal device is picture one, and the picture one is the current frame picture. The continuous N frame pictures adjacent to the current frame picture are the pictures displayed before the picture one.

[0061] Generally, the continuous N frames of pictures adjacent to the current frame of picture are the adjacent continuous N frames of pictures that have been displayed before, but in some terminal devices, if the terminal device can cache some pictures that have not been displayed in advance, the continuous N frames of pictures here can include some pictures that have not been displayed and are adjacent to the current frame of picture. For example, in the process that a user uses a terminal device, the application pictures displayed by the terminal device include picture one, picture two, picture three and picture four in turn, if N is 3 and the current frame of picture is picture four, then the adjacent continuous 3 frames of pictures here are the picture one, picture two and picture three that have been displayed before. In the terminal device with the function of caching pictures, the displayed application pictures include picture one, picture two and picture three, the current frame of picture is picture four, and the application pictures that have not been displayed include picture five and picture six, if N is 2, then the adjacent continuous 3 frames of pictures here are the picture two, picture three that have been displayed before and the cached picture five and picture six.

[0062] Of course, in actual application, the value of N can be set by the developer or the user. And whether the continuous N frames of pictures adjacent to the current frame of picture are taken from the adjacent N frames of historical picture frames or the adjacent N frames of cached picture frames that have not been displayed can be changed flexibly, which is not limited here. Taking the case of taking the adjacent N frames from the cached picture frames that have not been displayed as an example, in a possible implementation, N is 5, in the terminal device with the function of caching pictures, the displayed application pictures include picture one, picture two and picture three, the current frame of picture is picture four, and the cached picture frames that have not been displayed include picture five and picture six, the terminal device can take picture five and picture six as two frames of the continuous N frames of pictures adjacent to the current frame of picture, and take the adjacent (N-2) frames of historical picture frames, i.e. picture one, picture two and picture three, as the remaining three frames of the continuous N frames of pictures adjacent to the current frame of picture, so as to obtain the picture data of the continuous 5 frames of pictures adjacent to the current frame of picture.

[0063] Optionally, the picture data of each frame of picture is used to indicate the data amount of rendering a frame of picture by the terminal device; that is, the complexity of each frame of picture can be reflected. The larger the picture data of a frame of picture is, the higher the complexity of the frame of picture is, and the larger the data amount of rendering the frame of picture by the terminal device is. For example, for a frame of picture to be rendered by the terminal device, the terminal device can obtain the number of layers of the frame of picture, the more the number of layers is, the higher the complexity of the frame of picture is, and the larger the data amount of rendering the frame of picture by the terminal device is. Alternatively, the terminal device can obtain the number of brushes included in the frame of picture, the more the number of brushes is, the more the color types of the frame of picture are, the higher the complexity of the frame of picture is, and the larger the data amount of rendering the frame of picture by the terminal device is.

[0064] That is, for a frame of picture, the amount of data of the terminal device rendering the picture can be described by the number of angles, and the terminal device can acquire one of the numbers of angles as picture data and record, and acquire from the recorded data when needed.

[0065] Taking the number of layers of picture data of each frame of picture as an example, the terminal device can acquire the picture data of the current frame of picture and the picture data of the continuous N frames of picture adjacent to the current frame of picture in the following way: recording and storing the number of layers of each frame of picture in real time by a counter; acquiring the number of layers of the current frame of picture and the number of layers of the continuous N frames of picture adjacent to the current frame of picture.

[0066] For example, a counter can be used in the terminal device to record the number of layers of the displayed picture frames, and a piece of memory is pre-divided from the memory space to store the recorded number of layers, and the number of layers of the continuous N frames of picture adjacent to the current frame of picture recorded in the memory is acquired when needed. For example, in the process of the user using the terminal device, taking the terminal device acquiring the continuous N frames of picture adjacent to the current frame of picture in the history as an example, the application picture displayed by the terminal device includes picture one, picture two, picture three and picture four in turn, if N is 3 and the current frame of picture is picture four, the terminal device has stored the number of layers of each picture (L1, L2, L3 and L4 respectively) in the display process, and the continuous 3 frames of picture adjacent to the current frame of picture are picture one, picture two and picture three, and the picture data of the current frame of picture that can be acquired by the terminal device is L4, and the picture data of the continuous 3 frames of picture adjacent to the current frame of picture is L1, L2 and L3.

[0067] In a possible implementation, the picture data of each frame of picture is the number of brushes of the picture; the terminal device can also record and store the number of brushes of each frame of picture in real time by a counter; and when acquiring the picture data, the number of brushes of the current frame of picture and the number of brushes of the continuous N frames of picture adjacent to the current frame of picture can be acquired. The specific implementation details can be referred to the above-mentioned manner of the number of layers, which will not be described here.

[0068] It should be noted that other parameters (one or more) of the picture frame can also be used to reflect the amount of data of the terminal device rendering a frame of picture in actual application, which will not be exemplified one by one here.

[0069] In step 302, the target data difference value is acquired according to the picture data of the current frame of picture and the picture data of the continuous N frames of picture adjacent to the current frame of picture, and the target data difference value is the maximum difference between the picture data of the current frame of picture and the picture data of each of the N frames of picture.

[0070] Optionally, after the terminal device acquires the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture, the terminal device can calculate the difference between each pair of picture data, obtain each difference value between the picture data of the current frame picture and the picture data of each frame picture, and select the maximum difference value from the difference values to obtain the target data difference value. For example, when N is 3, the picture data of the current frame picture and the picture data of each of the N frame pictures obtained above are [Y1, Y2, Y3, Y4], the terminal device calculates the difference between Y1 and each of Y2, Y3, and Y4, obtains (Y1-Y2), (Y1-Y3), and (Y1-Y4), and obtains the maximum difference value as the target data difference value.

[0071] Optionally, to avoid the negative value of the difference value, the absolute value of the difference value can be obtained, and the maximum difference value can be obtained from the absolute values of the difference values. That is, the maximum difference value refers to the maximum value of the absolute values of the difference values.

[0072] In a possible implementation, the execution of the above scheme can be periodic, that is, the terminal device starts to execute step 301 to acquire the picture data of each frame picture and complete the subsequent adjustment of the performance strategy every fixed period. In this case, when the terminal device executes step 302, the terminal device can obtain the target data difference value in the following manner: the terminal device can also uniformly regard the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture as a set, the set includes N+1 picture data, the terminal device calculates the difference between each pair of picture data in the set, and obtains the maximum difference value as the target data difference value. For example, when N is 2, the picture data of the current frame picture and the picture data of each of the N frame pictures obtained above are [Y1, Y2, Y3], the terminal device calculates the difference between each pair of picture data, obtains the absolute values of (Y1-Y2), (Y1-Y3), and (Y2-Y3), and obtains the maximum difference value as the target data difference value.

[0073] In a possible implementation, the picture data includes multiple data types, and different data types correspond to different weights. The terminal device can obtain the target data difference value in the following manner according to the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture: for each data type, the terminal device obtains a type data difference value from the picture data of the current frame picture and the picture data of each of the N frame pictures. The type data difference value is the maximum difference value between the picture data of the current frame picture and the picture data of each of the N frame pictures in the same data type. The terminal device calculates the target data difference value according to each type data difference value and the weight of each data type.

[0074] That is, there can be multiple types of picture data. Taking the above picture data as an example, the picture data includes the number of layers and the number of brushes, for a frame of picture, the terminal device can record the number of layers and the number of brushes, then the picture data of each frame of picture includes two types of data, the terminal device can also obtain the corresponding two types of picture data when obtaining, and the terminal device calculates the type data difference value according to each type of data. For example, the maximum difference value of the number of layers is calculated according to the number of layers of the current frame of picture and the number of layers of the N continuous frames of picture adjacent to the current frame of picture, and the maximum difference value of the number of brushes is calculated according to the number of brushes of the current frame of picture and the number of brushes of the N continuous frames of picture adjacent to the current frame of picture. The maximum difference value of the number of layers and the maximum difference value of the number of brushes are the type data difference values, and the terminal device calculates the target data difference value by combining the weights corresponding to each type of data.

[0075] Taking the maximum difference value of the number of layers Lmax and the maximum difference value of the number of brushes Hmax calculated above as an example, the weight corresponding to the number of layers in the terminal device is θ1, and the weight corresponding to the number of brushes is θ2, then the terminal device calculates the target data difference value according to the following formula: target data difference value = Lmax*θ1+Hmax*θ2. Optionally, the different weights corresponding to different types of data can be flexibly set by the developer or the user.

[0076] Step 303, in the case that the target data difference value is greater than the preset difference threshold, determining the data range in which the picture data of the current frame of picture is located.

[0077] Step 304, determining the performance strategy corresponding to the data range according to the data range.

[0078] Step 305, adjusting the current performance strategy of the processor to the performance strategy corresponding to the data range.

[0079] Optionally, after obtaining the target data difference value, the target data difference value is compared with the preset difference threshold, if the target data difference value is greater than the preset difference threshold, steps 303 to 305 are executed to adjust the performance strategy of the processor, if the target data difference value is not greater than the preset difference threshold, no processing is performed and the current performance strategy of the processor continues to run.

[0080] Optionally, the target data difference value is the maximum difference value between the picture data of the current frame of picture and the picture data of each of the N frames of picture, and the picture data is the data amount indicating that the terminal device performs rendering of a frame of picture, if the target data difference value is greater, it means that the picture changes more and the change amount of the data amount for rendering by the terminal device is greater, at this time, the performance strategy of the processor needs to be adjusted.

[0081] Optionally, the terminal device first determines a data range in which the picture data of the current picture frame is located, and determines the corresponding performance strategy through the data range. For example, refer to Table 1, which shows a correspondence table of data range and performance strategy according to an example embodiment of the present application.

[0082] Table 1: Correspondence of data range and performance strategy

[0083] If the terminal device determines that the picture data of the current picture frame is within the data range one, it means that the first performance strategy needs to be adopted. The terminal device adjusts the current performance strategy of the processor to the performance strategy corresponding to the data range.

[0084] Taking the number of picture data as an example, Table 1 can be as follows:

[0085] That is, if the number of picture data of the current frame is less than or equal to 5, the determined performance strategy is the first performance strategy, if the number of picture data of the current frame is greater than 5 and less than or equal to 10, the determined performance strategy is the second performance strategy, and if the number of picture data of the current frame is greater than 10, the determined performance strategy is the third performance strategy.

[0086] In a possible implementation manner, when performing step 305, the terminal device can perform the following: according to the determined performance strategy corresponding to the data range, obtaining a target value of a target working parameter; and adjusting the parameter value of the target working parameter to the target value, so that the processor reaches the performance strategy corresponding to the data range.

[0087] Optionally, the target working parameter includes one or more of the working frequency of the processor, the number of cores of the processor, the cache level of the processor, and the number of threads for rendering of the processor. The processor can be one or more of CPU, GPU, and DDR in the terminal device.

[0088] That is, each performance strategy set in advance in the terminal device corresponds to a target value of a target working parameter, and after the terminal device determines the performance strategy, the corresponding target value of the target working parameter can be obtained, and then the parameter value of the target working parameter of the current processor is adjusted to the target value, so that the processor reaches the performance strategy that needs to be adjusted. Taking the working frequency as an example, under the first performance strategy, the working frequency of the processor needs to be Q1 kHz, under the second performance strategy, the working frequency of the processor needs to be Q2 kHz, and under the third performance strategy, the working frequency of the processor needs to be Q3 kHz. If the terminal device determines that the performance strategy that needs to be adjusted is the second performance strategy, the working frequency of the processor can be adjusted to Q2 kHz, thereby meeting the requirement. Optionally, the adjustment of other parameters is similar, which will not be described here.

[0089] It should be noted that the power consumption of the processor of the terminal equipment corresponding to different performance strategies is different, and in the above example, the power consumption corresponding to the first performance strategy, the second performance strategy, and the third performance strategy is increasing in turn. That is, as the number of layers increases, the terminal equipment needs to render more data, and therefore consumes more power. The present scheme can adjust the performance strategy of the processor of the terminal equipment in a timely manner according to the picture data of the current frame picture when the target data difference is greater than the preset difference threshold, that is, when the application picture displayed by the terminal equipment changes greatly, and the number of pictures that the terminal equipment needs to render changes, at this time, the performance strategy of the processor of the terminal equipment can be adjusted in a timely manner according to the picture data of the current frame picture, so as to reduce the power consumption of the processor or increase the power consumption of the processor to meet the rendering requirements of the current picture.

[0090] In a possible implementation manner, when the picture data includes the number of layers, if the target data difference is greater than the preset difference threshold, the terminal equipment can further perform the following steps: if the number of layers of the current frame picture is greater than the number of layers of the adjacent N continuous frame pictures of the current frame picture, the terminal equipment can remove the target layer from the number of layers of the current frame picture and then render the current frame picture.

[0091] That is, when it is judged in the step 303 that the target data difference is greater than the preset difference threshold, the terminal equipment can further judge whether the number of layers of the current frame picture is greater than the number of layers of the adjacent N continuous frame pictures of the current frame picture, and if the number of layers of the current frame picture is greater than the number of layers of the adjacent N continuous frame pictures of the current frame picture, the terminal equipment can remove the target layer from the number of layers of the current frame picture and then render the current frame picture, thereby reducing the consumption of CPU resources and improving the rendering efficiency.

[0092] The target layer can be set by the developer in advance. For example, in a game application, the A layer can not be displayed, and therefore the developer can set the A layer as the target layer. In the present scheme, in addition to adjusting the performance strategy of the processor in the above manner, the A layer of the current frame picture can also not be rendered when the current frame picture is rendered, that is, the target layer is removed from the number of layers of the current frame picture, and then the current frame picture is rendered. The number of specific target layers is not limited herein.

[0093] Optionally, taking the implementation of the above scheme in a terminal device through Vulkan as an example. In the terminal device, a developer can insert a counter into an extended Vulkan API, the counter being used to collect the number of layers of each frame of picture in real time, and a storage area (buffer) is defined in a memory space, the storage area being used to store the collected number of layers (that is, the int value collected by the counter can be saved in the storage area). Taking the above N = 1 and the preset difference threshold = 2 as an example, the terminal device can obtain the difference between the number of layers of the current frame of picture and the number of layers of the previous frame of picture as the target data difference, if the difference is less than or equal to 2, the terminal device does not process, and the performance of the current processor is maintained, if the difference is greater than 2, the data is packaged into what form and reported to the processor for processing, so as to determine the performance strategy according to the number of layers of the current frame of picture.

[0094] Taking the processor being a CPU of the terminal device as an example, through the above scheme, the preset difference threshold = 2, if the number of layers of the application picture displayed by the terminal device changes from 1 to 6, the performance strategy determined by the terminal device is adjusted from the original first-level performance strategy to the second-level performance strategy, if the number of layers of the application picture displayed by the terminal device continues to change from 6 to 12, the performance strategy determined by the terminal device is adjusted from the original second-level performance strategy to the third-level performance strategy, and the scheduling priority of the display of the application picture in the process of using the application program can be realized.

[0095] It should be noted that in the case of N = 1, the terminal device can obtain the picture data of the current frame of picture and the picture data of the previous frame of picture, and execute the present scheme, or the terminal device can obtain the picture data of a frame of picture separated by several frames, and execute the present scheme. That is, the terminal device can execute the acquisition of the picture data of the current frame of picture and the acquisition of the picture data of the previous recorded frame of picture every several frames, and obtain the difference between the two, and in the case of being greater than the preset difference threshold, the performance strategy of the processor of the terminal device is adjusted according to the picture data of the current frame of picture.

[0096] To sum up, the terminal device acquires the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture, the picture data being used to indicate the data amount of rendering a frame picture, N being a positive integer; acquires a target data difference value according to the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture, the target data difference value being the maximum difference value between the picture data of the current frame picture and the picture data of each of the N continuous frame pictures; and adjusts the performance strategy of the processor of the terminal device according to the picture data of the current frame picture in a case where the target data difference value is greater than a preset difference threshold. The terminal device provided in the present application can acquire the picture data of a frame picture, the picture data being used to indicate the data amount of rendering the frame picture, and can acquire a target data difference value according to the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture. In a case where it is determined that the target data difference value is greater than a preset difference threshold, it indicates that the data amount of rendering has changed greatly, and at this time, the terminal device can adjust the performance strategy of the processor according to the picture data of the current frame picture, so as to meet the demand of the current frame picture on the performance of the processor, thereby avoiding the problems of insufficient performance or performance waste, improving the accuracy of adjusting the performance of the processor, and making the scheme of adjusting the performance of the processor more suitable for various application pictures.

[0097] In addition, for the case where the picture data contains multiple types in the present scheme, in addition to using one type to implement the acquisition of the target data difference value, the maximum difference value of each type can be calculated respectively, and then the final target data difference value required is calculated by combining the weight of each data type, so that the result of calculating the target data difference value can more accurately reflect the difference between the picture data of the current frame picture and the picture data of each of the N continuous frame pictures adjacent to the current frame picture, thereby improving the accuracy of adjusting the performance strategy of the terminal device. Moreover, the present scheme also acquires the number of layers of each frame picture in real time, and removes the target layer from the number of layers of the current frame picture in a case where the number of layers of the current frame picture is greater than the number of layers of each of the N continuous frame pictures adjacent to the current frame picture, that is, the resource pool of the GPU synthesized by the terminal device is reduced by part of the layers (target layers) to reduce the rendering pressure of the GPU, thereby further saving the power consumption of the terminal device.
