Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The CPU working frequency adjusting method provided by the embodiment of the disclosure is applied to a terminal installed with a frame drawing application. The frame drawing application has a frame drawing period in the running process. The frame drawing period may be understood as an adjacent two-frame image display interval.
In the embodiment of the present disclosure, the frame drawing application may be an APP application installed on the terminal, for example, the frame drawing application may be a game. The following description of the embodiments of the present disclosure will be given by taking a frame drawing application as an example, but the embodiments of the present disclosure are not limited to the frame drawing application as a game application, and may be other applications.
In the process of running the game on the terminal, the length of the frame drawing period of the game is not fixed and is positively correlated with the size of the game load and the CPU working frequency in 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 the lower the CPU operating frequency, the longer the frame drawing period, when the game load is the same. The extension of the frame drawing period will cause the display time of the next frame to be delayed, the higher the probability of visually causing the click phenomenon. In the related art, the CPU governor 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 finished. However, the CPU operating frequency adjustment period is asynchronous with the frame drawing period, and therefore, 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 adjustment of the operating frequency of a CPU according to an exemplary embodiment of the present disclosure. In fig. 1, it is assumed that the CPU supports two frequency bin settings of 1.0GHZ and 2.0 GHZ. When the CPU governor monitors that the load in a certain frequency modulation period is greater than the frequency-increasing load threshold (assuming that the frequency-increasing load threshold is 75 in fig. 1), the frequency is increased to 2.0GHZ (if the current frequency is 2.0GHZ, the frequency is maintained unchanged). Similarly, when the operating frequency of the CPU is at 2.0GHZ, if the load is detected to be less than the down load threshold in the current frequency modulation cycle (it is assumed that the down load threshold is 45 in fig. 1), the frequency is reduced to 1.0 GHZ.
However, the CPU governor 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 tweetnor period. Therefore, based on the acquisition of the CPU governor frequency modulation period and the adjustment of the CPU operating frequency, the drastic load change in the frame drawing period cannot be reflected in time. For example, in fig. 2, the system load is increased in the second frame drawing period, and a higher CPU operating frequency is needed to adapt to the current load change, whereas cpugovenor is obtained based on the CPU operating frequency adjustment period, and the system load change can only be detected at the end of the third fm period, and a larger delay has occurred in performing the frequency adjustment. This in turn causes a situation where a highly loaded game is run at a lower frequency in the third frame drawing period. Accordingly, the frame drawing period is lengthened, and the display time of the next frame is delayed, thereby bringing about frame loss or stuck hidden danger.
In view of this, the present disclosure provides a method for adjusting a CPU operating frequency, in which a load is obtained based on a frame drawing period and the CPU operating frequency is adjusted, so as to capture a load change in the frame drawing period in real time to adjust the frequency in real time, thereby reducing a probability of visually causing a stuck phenomenon.
Fig. 3 is a flowchart illustrating a CPU operating frequency adjustment method according to an exemplary embodiment, where as shown in fig. 3, the CPU operating frequency adjustment method is used in a terminal, and a frame drawing class application is installed on the terminal, and the method includes 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 present disclosure, the frame drawing period refers to a display interval between two adjacent frames, and may also be understood as acquisition of a system load in each frame. For example, the system load may be obtained at the end of each frame.
In step S12, the terminal CPU operating frequency is adjusted based on the comparison result of the acquired system load and the preset load threshold.
In the embodiment of the present disclosure, the system load is obtained in the frame drawing period, and the obtained system load is compared with a preset load threshold value, so as to adjust the operating frequency of the CPU of the terminal.
In the embodiment of the present disclosure, adjusting the operating frequency of the terminal CPU includes increasing the operating frequency of the terminal CPU, decreasing the operating frequency of the terminal CPU, 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 operating frequency is adjusted, so that the load change in the frame drawing period is captured in real time to adjust the frequency in real time, and the probability of visually blocking is reduced.
The embodiment of the present disclosure will be described below with reference to practical applications.
In the embodiment of the present disclosure, the operating frequency supported by the terminal is preset, and generally, the operating frequency is two or more operating frequencies with different sizes. Further, in the embodiment of the present disclosure, a load threshold for adjusting the operating frequency of the CPU may be preset according to the system performance of the terminal. In which, the embodiments of the present disclosure may set an ascending load threshold and a descending load threshold, respectively. And the frequency-increasing load threshold value is used for judging whether the working frequency is increased or not according to the frequency-increasing load threshold value. For example, when the currently acquired system load is greater than the frequency-increasing load threshold, the terminal CPU operating frequency is increased to a frequency higher than the current CPU operating frequency among the preset multiple operating frequencies, for example, the terminal CPU operating frequency is increased to a frequency with the highest CPU operating frequency. In the embodiment of the disclosure, a down-conversion load threshold value can be set, and whether the working frequency is reduced or not is judged through the down-conversion load threshold value. 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 the preset multiple 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 present disclosure, when the CPU operating frequency is adjusted, the CPU operating frequency may also be adjusted based on the current operating frequency of the terminal and the load threshold.
In an aspect of the embodiment 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 frequency-increasing load threshold, the operating frequency of the CPU of the terminal may be adjusted to be a higher operating frequency than the current operating frequency, for example, the operating frequency of the CPU of the terminal 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-loading threshold and less than the up-loading threshold, the CPU operating frequency of the terminal 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 obtained system load is greater than the frequency-increasing load threshold value, the working frequency of the CPU of the terminal can be kept to be the highest working frequency.
In another aspect of the embodiment 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 down-conversion load threshold, the operating frequency of the CPU of the terminal may be adjusted to be a lower operating frequency than the current operating frequency, for example, the operating frequency of the CPU of the terminal may be adjusted to be the lowest frequency among the preset operating frequencies.
In 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 less than the down-conversion load threshold, the CPU operating frequency of the terminal may be kept at the lowest operating frequency.
Fig. 4 is a schematic diagram illustrating adjustment of the operating frequency of a CPU according to an exemplary embodiment of the present disclosure. In fig. 4, it is assumed that the operating frequencies supported by the terminal are preset to be 1.0G and 2.0G. The up-loading threshold is 75 and the down-loading threshold is 45. In fig. 4, the system load in the first frame drawing period is 30+30 ═ 60, which is smaller than the frequency-increasing load threshold 75, and the current operating frequency 1.0G can be maintained. The system load in the second frame drawing period is 30+ 60-90, which is greater than the boost load threshold 75, and the operating frequency can be raised to 2.0G. The system load during the third frame rendering period is 90, which is greater than the ramp-up load threshold 75, and the current operating frequency can be maintained at the maximum operating frequency of 2.0G. And the system load in the third frame drawing period is 40, which is smaller than the frequency reduction load threshold value 45, and the reduced working frequency is 1.0G.
The up-loading threshold and the down-loading threshold referred to in the above embodiments of the present disclosure may be predetermined based on the terminal system performance. In one embodiment, the frequency-increasing load threshold is a frequency-increasing load threshold used when the CPU operating frequency is adjusted based on the CPU operating frequency adjustment period. The frequency reduction load threshold is used for adjusting the CPU working frequency based on the CPU working frequency adjustment period
It can be further understood that, in the embodiment of the present disclosure, when load acquisition is performed based on a frame drawing period and frequency adjustment is performed, a process of acquiring and frequency adjustment by using a CPU governor based on a CPU operating frequency adjustment period by a terminal may be temporarily cancelled.
In another embodiment of the present disclosure, when the load threshold is preset based on the system performance of the terminal, different load thresholds may be preset for different scenarios in response to a situation where the application has multiple scenarios. Wherein, different applied scenes can be identified by adopting an Artificial Intelligence (AI) technology. For example, when the application is a game, the scene may include hall waiting, resource loading, grass running, wild, driving, running, and the like. In the embodiment of the disclosure, the load threshold of each scene can be preset through big data analysis and sorting of the load change of the game in different scenes. Different scenarios correspond to different load thresholds.
In one embodiment, in the present disclosure, load thresholds corresponding to different scenarios may be stored in the cloud. When the application is initially installed at the terminal, the load threshold values of all scenes corresponding to the initially installed application are obtained from the cloud and are stored in the local terminal. 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 CPU operating frequency adjustment method according to an exemplary embodiment, where as shown in fig. 5, the CPU operating frequency adjustment method is used in a terminal, and a frame drawing class application is installed on the terminal, and the method includes the following steps.
In step S21, a load threshold is preset.
In an embodiment of the present disclosure, on the one hand, a load threshold may be preset based on system performance of a terminal. On the other hand, the load threshold matched with different scenes can be preset based on different scenes in the operation of the terminal installation application.
Further, the preset load threshold includes an up-loading threshold and a down-loading threshold.
The embodiments of the present disclosure take the example of distinguishing scenes and determining a load threshold value of a matching scene.
The terminal can obtain and store the load threshold corresponding to each scene of the application from the cloud when the application is initially installed.
In step S22, a current scene of the application running on the terminal is determined, and a load threshold matching the current scene is used as a preset load threshold.
In step S23, based on the frame drawing period, the periodic terminal runs a load applied in the frame drawing period in the current scene.
In the embodiment of the present disclosure, the system load obtained in each frame of the drawing period is compared with a preset frequency-increasing load threshold and a preset frequency-decreasing load threshold.
In step S24, when the acquired system load is greater than the frequency-increasing load threshold, the terminal CPU operating frequency is increased.
For example, the frequency-increasing load threshold value set for a certain game scene is 80, and when the system load in a certain frame drawing period exceeds the frequency-increasing load threshold value 80, the frequency is increased in real time, for example, the working frequency is increased from 1.0G to 2.0G, so as to quickly respond to the rapid increase of the system load and reduce the performance loss caused by untimely frequency increase of the conventional frequency-increasing strategies such as the CPU goveror.
In the embodiment of the disclosure, after the operating frequency of the CPU of the terminal is increased, the system load is continuously acquired with the frame drawing period as a period.
In step S25a, if the acquired system load is still greater than the frequency-increasing load threshold, the operation is maintained at the increased operating frequency.
In step S25b, when the acquired system load is lower than the down load threshold, the terminal CPU operating frequency is lowered. For example, in the embodiment of the present disclosure, the operating frequency of the CPU of the terminal may be reduced to the operating frequency before the operating frequency is increased.
In the embodiment of the present disclosure, the down-conversion load threshold may also be understood as a load threshold of the recovered operating frequency, for example, the load threshold for the recovered operating frequency is 60, and when it is obtained that the system load in a certain frame drawing period is lower than the load threshold of the recovered operating frequency, the frequency is recovered to a frequency point before frequency increase, for example, 1.0G.
Fig. 6 is a schematic diagram illustrating the adjustment of the operating frequency of the CPU shown in fig. 5. In fig. 6, it is assumed that the operating frequencies supported by the terminal are preset to be 1.0G and 2.0G. The up-loading threshold is 80 and the down-loading threshold is 60. In fig. 6, the system load during the first frame drawing period is 30, which is less than the frequency-increasing load threshold 80, and the current operating frequency can be maintained at 1.0G. The system load in the second frame drawing period is 80+ 10-90, which is greater than the frequency-increasing load threshold 80, and the operating frequency can be increased to 2.0G. The system load in the third frame drawing period is 80+ 10-90, which is greater than the frequency-increasing load threshold 80, so that the current operating frequency can be kept at the highest operating frequency of 2.0G. And the system load in the third frame drawing period is 40, which is smaller than the frequency reduction load threshold value 60, and the recovery working frequency is 1.0G.
The scheme for acquiring the system load based on the frame drawing period and adjusting the CPU working frequency provided by the embodiment of the disclosure can be used for monitoring and capturing the load change in the frame drawing period in real time, thereby adjusting the working frequency in time. In addition, different load thresholds are preset for loads in different scenes by dividing application scenes, so that the change of the real load of each application scene is quickly responded, and the unification of performance and power consumption is realized.
Based on the same conception, the embodiment of the disclosure also provides a CPU working frequency adjusting device.
It is understood that, in order to implement the above functions, the CPU operating frequency adjusting apparatus provided in the embodiments of the present disclosure includes a hardware structure and/or a software module corresponding to the execution of each function. The disclosed embodiments can be implemented in hardware or a combination of hardware and computer software, in combination with the exemplary elements and algorithm steps disclosed in the disclosed embodiments. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure.
