Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The CPU working frequency adjusting method provided by the embodiment of the disclosure is applied to the terminal provided with the frame drawing application. The frame drawing class application has a frame drawing period during operation. The frame drawing period can be understood as the display interval of two adjacent frames of images.
In the embodiment of the disclosure, the frame drawing class application may be an APP class application installed on the terminal, for example, the frame drawing class application may be a game. The embodiments of the present disclosure will be described below by taking a frame drawing application as an example of a game, and of course, the embodiments of the present disclosure are not limited to the frame drawing application as a game application, but may be other applications.
The length of the frame drawing period of the game is not constant during the running of the game on the terminal, and is positively correlated with the magnitude of the game load and the magnitude of the CPU operating frequency during the drawing period. The larger the game load in the frame drawing period, the longer the frame drawing period at the same CPU operating frequency. Or when the game load is the same, the lower the CPU operating frequency, the longer the frame drawing period. The longer the frame drawing period will result in a delay in the display time of the next frame, the higher the probability of visually appearing a stuck phenomenon. In the related art, the CPU gate monitors the change of the system load based on the CPU operating frequency adjustment period, and adjusts the operating frequency according to the monitored load in the CPU operating frequency adjustment period when each frequency modulation period is completed. However, the CPU operating frequency adjustment period is not synchronized with the frame drawing period, and thus, the load change in the frame drawing period cannot be captured in real time to make real-time adjustment of the CPU operating frequency.
Fig. 1 is a schematic diagram illustrating CPU operating frequency adjustment according to an exemplary embodiment of the present disclosure. In fig. 1, it is assumed that the CPU supports two frequency point settings of 1.0GHZ and 2.0 GHZ. When the CPU gate monitors that the load in a certain frequency modulation period is greater than the boost load threshold (assuming the boost load threshold is 75 in fig. 1), the boost frequency is 2.0GHZ (if the current frequency is 2.0GHZ, then it remains unchanged). Similarly, when the CPU operating frequency is at 2.0GHZ, if the load is monitored to be less than the down-conversion load threshold (assuming the down-conversion load threshold is 45 in FIG. 1) during the current frequency modulation period, the frequency is reduced to 1.0GHZ.
However, the CPU gate acquires the load based on the CPU operating frequency adjustment period. The game has its own frame drawing period, and the load of the game also fluctuates greatly in different frame drawing periods. Since the frame drawing period is not synchronized with the CPU gate frequency modulation period. Therefore, based on the acquisition of the CPU gate frequency modulation period and the CPU operating frequency adjustment, the drastic load change in the frame drawing period cannot be reflected in time. For example, in fig. 2, the system load is increased during the second frame drawing period, and a higher CPU operating frequency is required to adapt to the current load change, however, the CPU synthesizer acquires based on the CPU operating frequency adjustment period, and only detects the system load change at the end of the third frequency adjustment period, and then a larger delay has occurred in performing the frequency adjustment. Resulting in a third frame drawing period, when a high load game is run at a lower frequency. Correspondingly, the frame drawing period is prolonged, the display time of the next frame is delayed, and the hidden danger of frame loss or blocking is brought.
In view of this, the present disclosure provides a method for adjusting a CPU operating frequency, in which load acquisition is performed based on a frame drawing period and CPU operating frequency adjustment is performed, so as to achieve real-time capturing of a load change in the frame drawing period for real-time adjustment of frequency, and reduce the probability of occurrence of a visual stuck phenomenon.
Fig. 3 is a flowchart illustrating a method for adjusting a CPU operating frequency according to an exemplary embodiment, which is used in a terminal on which a frame drawing class application is installed, as shown in fig. 3, comprising the following steps.
In step S11, the frame drawing period of the application is acquired, and the system load of the terminal in each frame drawing period is periodically acquired based on the frame drawing period of the application.
In the embodiment of the disclosure, the frame drawing period refers to the display interval of two adjacent frames, and can be understood as the acquisition of the system load in each frame. For example, the acquisition of the system load may be performed at the end of each frame.
In step S12, the terminal CPU operating frequency is adjusted based on the comparison result of the obtained system load and the preset load threshold.
In the embodiment of the disclosure, system load acquisition is performed in a frame drawing period, and the acquired system load is compared with a preset load threshold value to adjust the working frequency of a terminal CPU.
In the embodiment of the disclosure, adjusting the terminal CPU operating frequency includes raising the terminal CPU operating frequency, lowering the terminal CPU operating frequency, and may also include maintaining the current operating frequency.
In the embodiment of the disclosure, the system load is acquired based on the frame drawing period and the CPU working frequency is adjusted, so that the real-time frequency adjustment of the load change in the frame drawing period is captured in real time, and the probability of occurrence of a visual stuck phenomenon is reduced.
The CPU operating frequency adjustment method according to the above embodiment will be described below in connection with practical applications.
In the embodiment of the disclosure, the working frequency supported by the terminal is preset, and is generally two or more working frequencies with different sizes. Further, in the embodiment of the present disclosure, a load threshold for adjusting the CPU operating frequency may be preset according to the system performance of the terminal. The embodiment of the disclosure can respectively set an up-conversion load threshold and a down-conversion load threshold. The frequency-raising load threshold is used for judging whether the working frequency is raised or not through the frequency-raising load threshold. For example, when the currently acquired system load is greater than the ascending load threshold, the terminal CPU operating frequency is raised to a frequency higher than the current CPU operating frequency among a plurality of preset operating frequencies, for example, the terminal CPU operating frequency is raised to a frequency with the highest CPU operating frequency. In the embodiment of the disclosure, a frequency-reducing load threshold may be set, and whether to reduce the working frequency is determined by the frequency-reducing load threshold. For example, when the currently acquired system load is smaller than the down-conversion load threshold, the terminal CPU operating frequency is reduced to a frequency lower than the current CPU operating frequency among a plurality of preset operating frequencies, for example, the terminal CPU operating frequency is reduced to a frequency with the lowest CPU operating frequency.
In the embodiment of the disclosure, when the CPU operating frequency is adjusted, the adjustment may also be performed based on the current operating frequency of the terminal and the load threshold.
In an aspect of the embodiments of the present disclosure, when the current operating frequency is not the highest operating frequency supported by the terminal and the obtained system load is greater than the ascending load threshold, the operating frequency of the terminal CPU may be adjusted to be higher than the operating frequency of the current operating frequency, for example, the operating frequency of the terminal CPU may be adjusted to be the highest frequency among a plurality of preset operating frequencies.
In another aspect of the embodiments of the present disclosure, when the obtained system load is greater than the down-conversion load threshold and less than the up-conversion load threshold, the terminal CPU operating frequency may be kept as the current operating frequency. Or when the current working frequency is the highest working frequency supported by the terminal and the acquired system load is greater than the ascending load threshold, the working frequency of the CPU of the terminal can be kept to be the highest working frequency.
In still another aspect of the embodiments of the present disclosure, when the current operating frequency is not the lowest operating frequency supported by the terminal and the obtained system load is less than the frequency-reducing load threshold, the operating frequency of the terminal CPU may be adjusted to be a lower operating frequency than the current operating frequency, for example, the operating frequency of the terminal CPU may be adjusted to be the lowest frequency among a plurality of preset operating frequencies.
In still another aspect of the embodiments of the present disclosure, when the current operating frequency is the lowest operating frequency supported by the terminal and the obtained system load is smaller than the frequency-reducing load threshold, the CPU operating frequency of the terminal may be kept to be the lowest operating frequency.
Fig. 4 is a schematic diagram illustrating a CPU operating frequency adjustment according to an exemplary embodiment of the present disclosure. The preset terminal is assumed to support operating frequencies of 1.0G and 2.0G in fig. 4. The boost load threshold is 75 and the down load threshold is 45. In fig. 4, the system load in the first frame drawing period is 30+30=60, which is smaller than the up-conversion load threshold 75, so that the current operating frequency 1.0G can be maintained. The system load in the second frame drawing period is 30+60=90, and is greater than the boost load threshold 75, the operating frequency can be raised to 2.0G. The system load during the third frame drawing period is 90, which is greater than the boost load threshold 75, to maintain the current operating frequency at the highest operating frequency of 2.0G. The system load in the third frame drawing period is 40, which is less than the down-conversion load threshold 45, and the operating frequency is reduced to 1.0G.
The boost load threshold and the buck load threshold referred to in the above embodiments of the present disclosure may be predetermined based on the terminal system performance. In one embodiment, the up-conversion load threshold is an up-conversion load threshold used when the CPU operating frequency is adjusted based on the CPU operating frequency adjustment period. The down-conversion load threshold is used when the CPU working frequency is adjusted based on the CPU working frequency adjustment period
It can be further understood that, in the embodiment of the present disclosure, when the load acquisition based on the frame drawing period is adopted and the frequency adjustment is performed, the process that the terminal acquires and performs the frequency adjustment based on the CPU operating frequency adjustment period by using the CPU gate may be temporarily canceled.
In another embodiment of the present disclosure, when a load threshold is preset based on the system performance of the terminal, different load thresholds may be preset for different scenarios for the case where the application has multiple scenarios. Among other things, different scenarios of an application may be identified using artificial intelligence (Artificial Intelligence, AI) techniques. For example, where the application is a game, the scene may include lobby waiting, resource loading, grassland running, wild, driving, etc. According to the embodiment of the disclosure, the load threshold value of each scene can be preset by analyzing and sorting the load change of the game under different scenes through big data. Different scenarios correspond to different load thresholds.
In one embodiment, the load thresholds corresponding to different scenarios may be stored in the cloud. When the terminal initially installs the application, the load threshold value of all scenes corresponding to the initially installed application is obtained from the cloud end and stored in the terminal local. When the terminal runs the application, determining a current scene of the application running on the terminal, taking a load threshold matched with the current scene as a preset load threshold, and judging whether the frequency is adjusted or not based on the load threshold.
Fig. 5 is a flowchart illustrating a method for adjusting a CPU operating frequency according to an exemplary embodiment, which is used in a terminal on which a frame drawing class application is installed, as shown in fig. 5, comprising the following steps.
In step S21, a load threshold is preset.
In one aspect, in the embodiments of the present disclosure, a load threshold may be preset based on a system performance of a terminal. On the other hand, the embodiment of the disclosure can also preset load thresholds matched with different scenes based on different scenes when the terminal installs the application to run.
Further, the preset load threshold includes an up-conversion load threshold and a down-conversion load threshold.
The embodiments of the present disclosure will be described with respect to distinguishing load thresholds of scene determination matching scenes.
The terminal can acquire and store load thresholds corresponding to various scenes of the application from the cloud when the application is initially installed.
In step S22, a current scenario of the application running on the terminal is determined, and a load threshold value matched with the current scenario is used as a preset load threshold value.
In step S23, the periodic terminal runs the load applied in the frame drawing period in the current scene based on the frame drawing period.
In the embodiment of the disclosure, the system load obtained in each frame drawing period is compared with a preset frequency-up load threshold and frequency-down load threshold.
In step S24, when the obtained system load is greater than the boost load threshold, the terminal CPU operating frequency is increased.
For example, the frequency-raising load threshold value set for a certain game scene is 80, when the system load in a certain frame drawing period is obtained to exceed the frequency-raising load threshold value 80, frequency raising is performed in real time, for example, the working frequency is raised from 1.0G to 2.0G, so that the rapid response of the rapid increase of the system load is realized, and the performance loss caused by the fact that the frequency raising is not performed in time by a conventional frequency raising strategy such as a CPU (Central processing Unit) gate or the like is reduced.
In the embodiment of the disclosure, after the working frequency of the terminal CPU is increased, system load acquisition is continuously performed by taking the frame drawing period as a period.
In step S25a, when the acquired system load is still greater than the boost load threshold, operation at the increased operating frequency is maintained.
In step S25b, when the acquired system load is lower than the down-conversion load threshold, the terminal CPU operating frequency is reduced. For example, in the embodiment of the disclosure, the operating frequency of the terminal CPU may be reduced to an operating frequency before the operating frequency is increased.
In the embodiment of the disclosure, the above-mentioned frequency-reducing load threshold may also be understood as a load threshold for recovering the operating frequency, for example, the load threshold for recovering the operating frequency is 60, and when the system load in a certain frame drawing period is obtained to be lower than the load threshold for recovering the operating frequency, the frequency is recovered to the frequency point before frequency raising, for example, 1.0G.
Fig. 6 is a schematic diagram showing the adjustment of the CPU operating frequency shown in fig. 5. In fig. 6, it is assumed that the preset terminal supports the operating frequencies of 1.0G and 2.0G. The boost load threshold is 80 and the down load threshold is 60. In fig. 6, if the system load in the first frame drawing period is 30 and is less than the up-conversion load threshold 80, the current operating frequency can be maintained at 1.0G. The system load in the second frame drawing period is 80+10=90, and is greater than the boost load threshold 80, the operating frequency can be raised to 2.0G. The system load in the third frame drawing period is 80+10=90, and is greater than the up-conversion load threshold 80, so that the current operating frequency can be kept to be the highest operating frequency of 2.0G. The system load in the third frame drawing period is 40, which is less than the down-conversion load threshold 60, and the recovery operating frequency is 1.0G.
The scheme for acquiring the system load based on the frame drawing period and adjusting the CPU working frequency can be used for monitoring and capturing the load change in the frame drawing period in real time, so that the working frequency can be adjusted in time. And by dividing application scenes, different load thresholds are preset for loads in different scenes, so that the change of the actual load of each application scene is responded quickly, and the unification of performance and power consumption is achieved.
Based on the same conception, the embodiment of the disclosure also provides a CPU working frequency adjusting device.
It can be understood that, in order to implement the above-mentioned functions, the CPU operating frequency adjusting device provided in the embodiments of the present disclosure includes a hardware structure and/or a software module that perform each function.

Those skilled in the art may implement the described functionality using different approaches for each particular application, but such implementation is not to be considered as beyond the scope of the embodiments of the present disclosure.
