The software and hardware operating environment of the present application is introduced above, and the following describes in detail a method for controlling a frequency of a central processing unit in an embodiment of the present application with reference to fig. 2, where fig. 2 is a schematic flow chart of the method for controlling a frequency of a central processing unit provided in the embodiment of the present application, and specifically includes the following steps:
The method comprises the steps that firstly, a processor can monitor the system state of the electronic equipment, when a target application is started, the processor can call a key thread formed by a UI thread and a related thread corresponding to the target application to draw the target application, and receive drawing data of the key thread, wherein the drawing data can comprise drawing time consumed by the UI thread for drawing a frame of image aiming at the target application, and the drawing time can reflect the current actual frame rate of the target application.
The target frame rate data of the target application may be obtained first, and then the drawing data is calculated to obtain the current actual frame rate data of the target application, it can be understood that, in the present application, the meaning of the X frame is that an X frame image is transmitted every second, the actual frame rate data is set to be N, and the drawing duration is set to be M, and then the actual frame rate data may be obtained by combining the following formula:
specifically, the target frame rate data may include a target frame rate and a preset frame drop duration, where the target frame rate may reflect a frame rate requirement of the target application, for example, the target frame rate of the game application may be 60 frames, the expected frame rate of the video application may be 30 frames, and the preset frame drop duration may be set to 0.5 second, for example, in a scene of the game application, a frame drop may be considered when an actual frame rate is lower than 60 frames and exceeds 0.5 second, and a frame drop may not be considered when an actual frame rate is lower than 60 frames and does not exceed 0.5 second. If the actual frame rate is lower than the target frame rate and the frame dropping duration of the actual frame rate lower than the target frame rate is greater than the preset frame dropping duration, determining that the target application has a frame dropping condition, and executing step 203; if the actual frame rate is equal to the target frame rate, the working frequency of the CPU is maintained, and the system operation state of the electronic equipment is continuously monitored.
Therefore, whether the target application is in the frame dropping and blocking or not is judged by drawing data, whether the target application is in the frame dropping and blocking or not can be accurately detected under the condition that the running of the target application is not influenced, and the use experience of a user using the target application is not influenced.
When the target application has a frame drop condition, executing the step.
The method comprises the steps of firstly inquiring the current working frequency of a CPU and the current working core of the CPU, specifically, acquiring the identification data of the key thread, then inquiring the current working frequency of the CPU and the current working core corresponding to the key thread based on the identification data, and judging whether the CPU is in a full-load working state or not by judging whether the current working frequency reaches a preset frequency or whether the current working core is a main working core.
If the CPU is in a full load working state, warning information can be sent to a user, wherein the warning information is used for indicating that the CPU is overloaded and is not described again; if the CPU is not in the full load operating state, step 204 is executed.
Therefore, whether the central processing unit is in a full-load working state or not is judged, the working frequency of the central processing unit can be conveniently and dynamically adjusted, a user can be timely notified when automatic adjustment cannot be carried out, and the use experience of the user is optimized.
And 204, improving the working frequency of the central processing unit based on the drawing data.
Fig. 3 is a schematic flowchart of a process of step 204 provided in this embodiment, and specifically includes the following steps:
For example, when the target application is a video-type application and the target frame rate data is 30 frames, the time consumed for drawing one frame of image should be 33.3 milliseconds, and at this time, the drawing time condition may be determined to be 33.3 milliseconds.
And 302, increasing the working frequency of the central processing unit until the drawing time meets the drawing time condition.
For example, when the drawing time condition is 33.3 milliseconds, the amplitude of the drawing time exceeding 33.3 milliseconds can be preset to be within 5 milliseconds, within 5 milliseconds to 10 milliseconds, and corresponding CPU operating frequency increasing amplitude from 10 milliseconds to 15 milliseconds, and it can be understood that the larger the amplitude of the drawing time exceeding 33.3 milliseconds is, the larger the corresponding CPU operating frequency increasing amplitude is, and after the drawing time meets the drawing time condition, the CPU operating frequency is maintained unchanged, and the system operating state of the electronic device is continuously monitored.
Therefore, the working frequency of the CPU is dynamically improved, the working frequency of the CPU can be ensured to be close to the actual requirement of the target application as far as possible, and the power consumption of the CPU can be reduced under the condition that the target application is not dropped and is blocked.
Optionally, another method of step 204 is described in detail with reference to fig. 4, where fig. 4 is a schematic flow chart of another step 204 provided in this embodiment of the present application, and specifically includes the following steps:
The current frequency data of the CPU, which represents the current operating frequency, may be determined in combination with the drawing duration.
The target frequency data indicates the operating frequency of the CPU required by the target application to reach the target frame rate, and may be obtained by querying related information of the target application, for example, the operating frequency of the CPU required by the game application to reach 60 frames is generally higher than the operating frequency of the CPU required by the video application to reach 30 frames, and different target applications may correspond to different target frequency data, where it is to be noted that the target frequency data is not greater than the maximum frequency supported by the CPU.
Wherein, the frequency boost value data of the CPU can be obtained by calculating the difference value between the current frequency data and the target frequency data.
And step 404, increasing the working frequency of the central processing unit based on the working frequency increase value.
And the working frequency of the CPU can be directly increased according to the frequency increasing value data, so that the working frequency of the CPU accords with the target frequency data.
It can be understood that the implementation methods of the two steps 204 in fig. 3 and fig. 4 can be performed synchronously, and the processor can flexibly switch specific implementation manners according to its own working state, the current process working state, and the like, so that various options can be provided for the method for improving the working frequency.
Therefore, the method determines whether the current application program has the conditions of frame dropping and the like through the drawing data of the user interface thread, dynamically improves the working frequency of the CPU, and avoids the conditions of frame dropping, blocking and the like of the picture.
Fig. 5 is a flowchart illustrating another method for controlling a frequency of a central processing unit in this embodiment of the present application in detail, where fig. 5 is a flowchart illustrating another method for controlling a frequency of a central processing unit in this embodiment of the present application, and specifically includes the following steps:
For a specific implementation, please refer to the method of step 201 in fig. 2, which is not described herein again.
For a specific implementation, please refer to the method of step 202 in fig. 2, which is not described herein again.
If the target application does not have the frame dropping condition, executing step 503; and if the target application has a frame drop condition, dynamically increasing the current working frequency of the CPU.
The drawing data comprises drawing time consumed by the UI thread for drawing one frame of image for the target application, and when the drawing time is shorter than the target drawing time corresponding to the frame rate required by the target application and the difference value exceeds a preset time range, the CPU working frequency is far higher than the CPU working frequency required by the target application at the moment, the CPU working frequency is in a performance excess state, and the CPU current working frequency needs to be reduced. For example, if the target application is a user interaction application, the required frame rate is 60 frames, the target drawing time is 16.6 milliseconds at this time, and the preset time range is 5 milliseconds, it can be determined that when the drawing time is less than or equal to 11.6 milliseconds, the current operating frequency of the CPU is too high, and the current operating frequency of the CPU needs to be reduced; when the drawing time length is more than 11.6 milliseconds and less than or equal to 16.6 milliseconds, the current working frequency of the CPU is only slightly more than the working frequency of the CPU required by the user interaction application to reach 60 frames, the CPU is not in a performance excess state, and the current working frequency of the CPU is not required to be reduced. It can be understood that the preset duration range can be flexibly changed according to the self requirements of the user.
If the cpu is in a performance excess state, go to step 504; if the cpu is not in the performance excess state, the operation of step 501 is repeatedly executed.
Specifically, how to reduce the operating frequency of the CPU is described in detail in the example in which the target application is the user interaction application, and it can be known from the above example that the frame rate requirement of the user interaction application is 60 frames, the target drawing time length is 16.6 milliseconds, and the preset time length range is 5 milliseconds, so that the current operating frequency of the CPU is reduced until the drawing time length of the UI thread for the user interaction application is greater than 11.6 milliseconds and less than or equal to 16.6 milliseconds, and the frequency reduction operation on the CPU is stopped. And then, continuously monitoring the system state of the electronic equipment.
By the method, when the working frequency of the CPU exceeds that of the CPU required by the target application to reach the target frame rate, the working frequency of the CPU is timely reduced to that required by the target application to reach the target frame rate, and the phenomenon of performance waste of the CPU is avoided while the experience of a user using the target application is not influenced.
For convenience of understanding, an application scenario of a method for controlling the frequency of the central processing unit in the embodiment of the present application is illustrated below with reference to fig. 6A and 6B, where an application program currently running on the electronic device is a game-like application, and specifically, a finger of a user is required to swipe a virtual button area on a screen to control a character in a game to move correspondingly. It should be noted that, under the normal operation condition, as shown in fig. 6A, the frame rate of the game-like application is 60 frames, which meets the frame rate requirement, that is, the character moving track in the game is smooth and natural movement, and the user can control the character in the game to smoothly move from point a to point B without feeling frame stutter; in the case of abnormal operation, as shown in fig. 6B, when the actual frame rate of the game-like application is lower than 60 frames, a display abnormality occurs, and when a user operates a character in the game to move from point a to point B, the character in the game is stopped at point a and moves to point B after a while, and a phenomenon of frame dropping and pausing occurs.
In this embodiment, the processor may monitor an operating state of the electronic device system, when a game application program is running, the processor may invoke a UI thread and a thread corresponding to the game application program to draw the game application program in real time, so as to obtain real-time drawing data, where the drawing data may include a drawing time consumed by the UI thread to draw a frame of image for the game application program, and the processor may determine, according to the drawing time, whether a current actual frame rate of the game application program corresponds to 60 frames, specifically, since 60 frames are 60 frames per 1 second, when the actual frame rate is 60 frames, the time consumed by drawing a frame of image should be 16.6 milliseconds, a current actual frame rate may be calculated by reverse derivation according to the drawing time according to the calculation rule, and if the current actual frame rate corresponds to 60 frames, the operating state of the electronic device system is continuously monitored, if the current actual frame rate does not meet 60 frames, two situations of non-compliance may occur, one is that the current actual frame rate is lower than 60 frames, and the other is that the current actual frame rate is higher than 60 frames, which are sequentially described as follows:
when the current actual frame rate of the game application is lower than 60 frames, inquiring the current working state information of the CPU, and judging whether the CPU is in a full load working state or not based on the current working state information of the CPU, wherein the working state information can comprise the current working frequency of the CPU, the CPU core information operated by the current key thread and the like, if the current working frequency of the CPU is lower than the preset maximum working frequency or the CPU core operated by the current key thread is not the main core of the CPU, the CPU is not in the full load working state, and at the moment, the working frequency of the CPU can be dynamically increased until the actual frame rate of the game application accords with 60 frames;
when the current actual frame rate is higher than 60 frames, the working state information of the CPU is inquired at first, the current working frequency and the CPU core information of the key thread operation are obtained, then the working frequency of the CPU is dynamically reduced by combining the drawing data, specifically, the preset time length range can be set as a, and when the drawing time length is less than 16.6 milliseconds or the difference value of the drawing time length less than 16.6 milliseconds is greater than a, the working frequency of the CPU is reduced until the drawing time length belongs to (16.6-a, 16.6).
It should be noted that, the current actual frame rate is calculated according to the drawing time, and in the actual use of some target applications, a frame locking situation may occur, that is, the target application may lock the maximum frame rate to 60 frames, and at this time, the current actual frame rate of the target application may be 60 frames, but the actual frame rate calculated according to the drawing time is greater than 60 frames.
It is to be understood that the application scenario is an alternative embodiment, and does not represent a limitation of the present application, and the embodiment may also be applied to various application programs such as a video application, a camera application, a user interaction application, and the like, and is not limited to a game application.
Therefore, whether the current frame rate of the target application meets the requirement of the target frame rate is determined by obtaining the drawing data, and the working frequency of the CPU is dynamically improved by combining the current working state of the CPU and the drawing data, so that the phenomenon of frame dropping and blocking is avoided, the use experience of a user when the target application program is used is greatly improved, and meanwhile, when the working frequency of the CPU is too high, the working frequency of the CPU is dynamically reduced by combining the current working state of the CPU and the drawing data, so that the performance waste of the CPU is avoided.
The following is a schematic flow chart of another method for controlling a frequency of a central processing unit in the embodiment of the present application, which reflects relevant steps as a whole, and as shown in fig. 7, the specific steps include:
If the target application has a frame drop condition, executing step 703; if the target application does not have a frame drop, step 705 is executed.
If the cpu is in a full load operating state, step 704 is executed.
If the cpu is in a performance excess state, go to step 706; if the cpu is not in the performance excess state, the operation of step 701 is repeatedly executed.
The steps that are not described in detail may refer to some or all of the method steps in fig. 2, fig. 3, fig. 4, and fig. 5, and are not described again here.
By the method, whether the target application is in the frame dropping and blocking state or not can be judged based on the drawing data, the working frequency of the CPU is dynamically increased to prevent the target application from being in the frame dropping and blocking state, the performance of the CPU is saved to the maximum extent when the frame dropping and blocking state does not exist, and the power consumption of the electronic equipment is reduced while the use experience of a user is not influenced.
