Technical Field

[0002] At present, when performing frequency modulation, each hardware platform calculates the load frequency through scheduled jiffies update or periodic sampling to vote for frequency modulation. However, the sampling load results are random, so the sampled point may be the point with the heaviest load. At this time, the voting frequency is high after the decision algorithm. If the load after frequency modulation is executed is the time point in the second half of a frame, there will be excessive power consumption. If the sampled point is the lightest load point, the voting frequency after the decision algorithm is relatively low. If the load after frequency modulation is executed is the high load time point in the first half of a frame, the computing power is insufficient and stalled, resulting in serious performance degradation. Summary of the invention

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0024] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0025] In related technologies, such as mobile terminals, the final goal is to display content on the terminal screen, such as an LCD / OLED display. In fact, the display is triggered by the frame synchronization signal to send and process display data, and the data load of a frame is regular. However, when the jiffies update scheduled by the system is used as a trigger condition, the load is sampled at a random time point in a frame, which makes it possible to sample the point with the heaviest load, and the load after the frequency modulation is executed may be the time point in the second half of a frame, which will cause excessive power consumption, waste energy and generate heat. At the same time, it is also possible to sample the point with the lightest load, resulting in the load after the frequency modulation is executed may be the time point with high load in the first half of a frame, which will lead to insufficient computing power and stall, resulting in serious performance degradation.

[0026] In order to solve the technical problems existing in the related art, the present application embodiment provides a dynamic voltage frequency adjustment method, see Figure 1 , Figure 1 It is a flow chart of a dynamic voltage and frequency adjustment method provided in an embodiment of the present application, and the method includes steps 101 to 103.

[0027] Step 101 : When a vertical synchronization signal is received, a load sampling is performed on a starting position of a target frame to obtain a first load.

[0028] In one embodiment, when frequency modulation is performed, whether a vertical synchronization signal is received is used to determine when to process each frame, and then the frequency is adjusted according to the determined target frame. At the beginning of the target frame, the frequency of the CPU link is adjusted according to the load condition. Specifically, at the beginning of the target frame, it is determined to start processing the target frame, and then the load is sampled at the starting position of the target frame to obtain a first load corresponding to the starting position.

[0029] For each frame, taking the rendering and synthesis of the scene as an example, the processing of each frame includes two parts: rendering and synthesis. First, the rendering process is performed, and then the synthesis process is performed after the rendering is completed. In the actual processing process, different requirements correspond to different loads. For example, when performing calculation rendering, the load is higher, while when performing synthesis, the load is lower.

[0030] In one embodiment, illustratively, referring to Figure 2 ,like Figure 2 As shown, the arrow on the black line indicates the moment when the vertical synchronization signal is received, that is, the moment when each frame starts. At the beginning of each frame, load sampling is performed at the starting position to determine the load condition at the starting position, and then the frequency of the CPU link is adjusted according to the actual load condition.

[0031] It should be noted that the starting position of the target frame can be the very beginning of a frame, or a certain time / position after the beginning. At the beginning of a frame, its load condition may not reach the actual load condition, so the starting position can be determined based on experience or experiments.

[0032] Step 102: Acquire a vertical synchronization offset, and perform load sampling on a target frame according to the vertical synchronization offset to obtain a second load.

[0033] In one embodiment, when frequency adjustment is performed, a vertical synchronization offset is obtained, and then load sampling is performed again on the target frame according to the vertical synchronization offset to obtain a second load, wherein the sampling points corresponding to the first load and the second load are different, and when load sampling is performed, real-time sampling is performed during real-time processing of a frame, that is, when load sampling is performed to obtain the second load, load sampling is performed when the target frame is processed to reach the sampling time / position to obtain the second load.

[0034] For example, when performing load sampling to obtain the second load, the sampling point for sampling can refer to Figure 2 As shown, specifically Figure 2 The arrows under the black line correspond to the positions where the sampling is performed based on the vertical synchronization offset.

[0035] In practical applications, the vertical synchronization offset can be pre-set, such as setting it to any value between 0-16.6ms according to actual conditions. That is, after receiving the vertical synchronization signal, load sampling is performed after a certain period of time, and the certain period of time that has passed is the time value set for the vertical synchronization offset. Usually, the vertical synchronization offset is obtained based on experimental and empirical data, and can be accurately set for the current scene. However, in actual applications, due to being in the same scene, there will be certain changes, which will lead to slight changes in the specific vertical synchronization offset. Therefore, when obtaining the vertical synchronization offset and performing load sampling based on the vertical synchronization offset to obtain the second load, it is necessary to determine the currently obtained vertical synchronization offset.

[0036] According to the actual processing situation, the target frame obtained can be directly processed with the default vertical synchronization offset, or it can be dynamically adjusted according to the actual processing results to complete more accurate load sampling. Therefore, when obtaining the vertical synchronization offset, it includes: determining whether the target frame is an adjustment frame; when the target frame is a non-adjustment frame, obtaining the vertical synchronization offset corresponding to the target frame; when the target frame is an adjustment frame, obtaining the historical load sampling result according to the target frame, and determining the vertical synchronization offset according to the historical load sampling result.

[0037] It should be noted that in determining whether it is necessary to dynamically adjust the vertical synchronization offset, and determining whether and when to adjust the vertical synchronization offset, it can be determined based on the currently starting frame. For example, when the current frame is the initial frame or the first few frames, since there is no basis for adjustment, the default vertical synchronization offset can be used as the basis for the second load sampling. After certain processing, the vertical synchronization offset can be dynamically adjusted based on the actual processing results and feedback.

[0038] Therefore, when obtaining the vertical synchronization offset, it is determined whether the currently started target frame is an adjustment frame. When it is determined that the target frame is a non-adjustment frame, the vertical synchronization offset corresponding to the target frame is directly used for subsequent processing. Conversely, when it is determined that the target frame is an adjustment frame, the historical load sampling result is obtained according to the target frame, and the vertical synchronization offset is dynamically updated based on the historical load sampling result for subsequent processing.

[0039] Among them, the default adjustment frame will be different according to the different setting methods. For example, when only the first ten frames are set to be processed with the default vertical synchronization offset, the first ten frames will be set as the default adjustment frame, that is, only when the target frame is a frame in the first ten frames, the default vertical synchronization offset will be used for subsequent processing. For another example, when setting an adjustment every ten frames, an adjustment is required when entering a new ten frames. For example, the 1st to 10th frames are the initial frames, the 11th to 20th frames are a ten-frame, the 21st to 30th frames are a ten-frame, and so on. The adjustment frames at this time are the 11th frame, the 21st frame, the 31st frame...the 10n+1st frame, and n is an integer greater than or equal to 1. For other frames in a cycle (ten frames), they can be set as non-adjustment frames, such as the 11th to 20th frames are the 12th to 20th frames in a cycle.

[0040] Furthermore, when determining whether the currently started target frame is an adjustment frame, the Figure 3 , Figure 3 It is a flowchart diagram of the steps of determining whether a target frame is an adjustment frame provided in an embodiment of the present application, wherein the steps include steps 301 to 305.

[0041] Step 301, determining whether the target frame is an initial frame;

[0042] Step 302, when the target frame is determined to be an initial frame, determining the target frame to be a non-adjusted frame;

[0043] Step 303, when it is determined that the target frame is not the initial frame, determining whether the target frame is the first frame in the adjustment period;

[0044] Step 304, when it is determined that the target frame is the first frame in the adjustment period, determine the target frame as an adjustment frame;

[0045] Step 305 : When determining the first frame in the target frame non-adjustment period, determine the target frame non-adjustment frame.

[0046] Specifically, first determine whether the target frame is the initial frame. From the above description, it can be obtained that the initial frame can be set to the first few frames to be processed, such as the first ten frames. Therefore, the first ten frames to be processed can be called initial frames. When the target frame is determined to be the initial frame, the target frame is judged to be a non-adjusted frame, otherwise further processing will be performed. When performing further processing judgment, determine whether the target frame is the first frame in an adjustment cycle. When it is determined that the target frame is the first frame in the adjustment cycle, the target frame is judged to be an adjusted frame, otherwise the target frame will be determined to be a non-adjusted frame.

[0047] Exemplarily, the adjustment period can be set according to actual circumstances, for example, it can be set as described above, with ten frames as one adjustment period, and the first frame in an adjustment period is used as an adjustment frame to determine a new vertical synchronization offset, while other frames in the adjustment period will use the new vertical synchronization offset for subsequent processing, including sampling and acquisition of the second load.

[0048] That is, when it is determined that the target frame is a non-adjusted frame, the vertical synchronization offset corresponding to the target frame can be directly read for subsequent processing, and when it is determined that the target frame is an adjusted frame, it is necessary to dynamically adjust the vertical synchronization offset. When performing dynamic adjustment to obtain the vertical synchronization offset corresponding to the target frame, it includes: according to the target frame, obtaining load sampling results of several frames; analyzing each frame in the several frames to determine the offset value corresponding to each frame; and calculating the mean based on the offset value to obtain the vertical synchronization offset corresponding to the target frame.

[0049] Specifically, when it is determined that the target frame is an adjustment frame, the load sampling results of several frames are obtained according to the target frame, and then each frame is analyzed and processed to determine the actual offset value corresponding to each frame, and then the vertical synchronization offset corresponding to the target frame is obtained by averaging all the obtained offset values.

[0050] For example, when determining that the target frame is an adjustment frame, certain analysis and processing can be performed based on actual historical load results and data to obtain the load conditions during actual use, and then the vertical synchronization offset can be determined more accurately to perform sampling and frequency adjustment more accurately.

[0051] Taking the above-described ten frames as an adjustment cycle as an example, when the target frame is determined to be the 10n+1th frame, and n is an integer greater than or equal to 1, when obtaining the load sampling results of several frames according to the target frame, the load conditions of a certain number of frames in the past can be obtained. For example, when n is equal to 2, that is, the target frame is the 31st frame, when obtaining the historical load results and data, the actual load conditions of each frame from the 21st frame to the 30th frame can be obtained. By analyzing each frame, the offset value of each frame in the actual processing is determined, and then the average of the 10 offset values ​​is calculated, and the obtained average value is used as the vertical synchronization offset of the target frame. That is, the average value obtained at this time will be used as the sampling basis for each frame in the next adjustment cycle (the 31st frame to the 40th frame).

[0052] It should be noted that in actual applications, in addition to determining the adjustment frame and the corresponding vertical synchronization offset in the above manner, each frame can also be processed in real time, that is, except for the initial frame using the default vertical synchronization offset for sampling processing, each other frame will be adjusted in real time according to the actual historical load conditions, such as the 11th frame is updated according to the load conditions of the 1st to 10th frames, the 12th frame is updated according to the load conditions of the 2nd to 11th frames, the 13th frame is updated according to the load conditions of the 3rd to 12th frames, and so on. When updating, the average calculation method can also be used for processing.

[0053] That is, when it is determined that the target frame is not the initial frame, the target frame is judged to be an adjustment frame. At this time, the load conditions of each frame within a cycle are obtained according to the target frame, and analyzed and processed to obtain the offset value of each frame, and then the vertical synchronization offset corresponding to the target frame is obtained by average calculation.

[0054] Further, when a vertical synchronization offset is obtained, and a load is sampled on a target frame according to the vertical synchronization offset to obtain a second load, the method includes: determining a sampling point for sampling on the target frame according to the vertical synchronization offset and the starting position, and performing load sampling at the sampling point to obtain the second load. Specifically, the vertical synchronization offset is the position / time interval between the sampling point for sampling the first load and the sampling point for sampling the second load, so when sampling to obtain the second load, it is first necessary to determine a sampling point on the target frame according to the vertical synchronization offset and the starting position, and then perform load sampling to obtain the second load when the sampling point is reached.

[0055] Reference Figure 2 ,exist Figure 2 In the frequency modulation scenario shown, the position indicated by arrow 1 is the starting position, and the position indicated by arrow 2 can be obtained according to the vertical synchronization offset, and the position indicated by arrow 2 is the position where sampling is performed to obtain the second load.

[0056] Step 103: According to the first load and the second load, frequency modulation is performed on the CPU link when processing the target frame.

[0057] In one embodiment, after the first load and the second load are obtained, the CPU link is frequency modulated according to the obtained first load and the second load.

[0058] For example, when processing, Figure 2 Position, when performing frequency modulation processing, the area included by arrow 1 and arrow 2 will be frequency adjusted according to the first load sampled at arrow 1, and the area included by arrow 2 and arrow 3 (the beginning of the next frame adjacent to the target frame) will be frequency adjusted according to the second load sampled at arrow 2.

[0059] Normally, when processing each frame, the loads at different locations in different frames of the scene are different. For example, when processing a frame, rendering is performed first and then synthesis is performed to complete the processing of the frame. Obviously, the load situation is not constant during processing, and there are also large differences in the demand for CPU during rendering and synthesis, which leads to different demands for load, and a situation where the load is heavy at the beginning and light at the end, that is, the load is heavier during rendering and lighter during synthesis. At this time, frequency modulation processing will be performed according to the first load and the second load obtained by real-time sampling, which can effectively avoid insufficient computing power in heavy-load areas and waste of computing power in light-load areas.

[0060] Further, when frequency modulation is performed according to the first load and the second load, referring to Figure 4 , Figure 4 It is a flowchart diagram of the steps of performing frequency modulation processing provided in an embodiment of the present application, wherein the steps include steps 401 to 403.

[0061] Step 401, obtaining a load adjustment table, and querying the load adjustment table to obtain a first link frequency and a second link frequency corresponding to a first load and a second load, respectively;

[0062] Step 402, splitting the target frame into a first part and a second part according to the vertical synchronization offset;

[0063] Step 403: frequency modulate the first part according to the first link frequency, and frequency modulate the second part according to the second link frequency.

[0064] Specifically, when frequency modulation is performed according to the first load and the second load, frequency modulation is performed on different areas, such as Figure 2 As shown, when the frequency modulation processing is not performed using the method of the present application, the default frequency is used for processing each frame, such as Figure 2 f0 shown in the figure, and when frequency modulation processing is performed based on the method of the present application, for the area included in arrows 1 and arrows 2, the adjusted frequency f1 can be used for subsequent processing, and for the area included in arrows 2 and arrows 3, the frequency f2 is used for subsequent processing, and the results of frequency modulation corresponding to different intervals, such as f1 and f2, need to be adjusted according to the actual load conditions.

[0065] Exemplarily, when determining the frequencies corresponding to the first load and the second load, a load adjustment table can be obtained, wherein the load adjustment table can be updated in real time, and then the first link frequency and the second link frequency corresponding to the first load and the second load are determined in the load adjustment table, and at the same time, the target frame is split according to the vertical synchronization offset and the initial position to obtain the first part and the second part, and finally, when performing frequency modulation processing, the first link frequency is used to perform frequency modulation processing on the first part, and the second link frequency is used to perform frequency modulation processing on the second part.

[0066] Furthermore, in actual applications, due to different scenarios, there are differences in load conditions. For example, in the rendering and synthesis scenarios mentioned above, there will be differences in the load in a frame, but in other scenarios, it may always be under heavy load, such as in a game scenario. In this case, when load sampling is performed to obtain the first load and the second load, the first load and the second load are the same or the load offset is small, and segmented frequency modulation may not be performed at this time.

[0067] Therefore, when the first load and the second load are obtained, it is determined whether the first load and the second load are the same or have a small difference, wherein a difference threshold can be set for a small difference, and when the difference between the first load and the second load is less than the difference threshold, it is determined that the difference is small, and then subsequent processing is performed based on the comparison result, specifically including: determining whether the first load and the second load are the same; when it is determined that the first load and the second load are the same, using the first link frequency for frequency modulation processing.

[0068] By comparing the first load and the second load, the performance impact caused by frequent frequency modulation when the load difference is small can be avoided.

[0069] In summary, the present application discloses a dynamic voltage frequency adjustment method. When performing frequency modulation processing, the moment of receiving the vertical synchronization signal is determined as the start of processing the target frame. At this time, the load sampling is performed at the starting position of the target frame to obtain the first load, so as to perform frequency modulation processing on the CPU link according to the first load, and the vertical synchronization offset at this time is obtained. In the process of processing the target frame, the second load is sampled again on the target frame according to the vertical synchronization offset, and the CPU link is frequency modulated again according to the second load. In the frequency adjustment process, the vertical synchronization signal is used as the start signal of the frame processing, and the load can be accurately acquired. Then, according to the vertical synchronization offset determined by the intra-frame features, the load can be accurately tracked, and the heavy load and light load can be accurately acquired. Then, for different intervals, the frequency is determined and adjusted according to the corresponding loads, and the matching of frequency modulation and computing power can be achieved more accurately, and both performance and power consumption can be taken into account.
