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.
First, it should be noted that the high and low operating frequencies of the processor represent the strength of the processing capability of the processor, and the higher the operating frequency of the processor is, the stronger the processing capability of the processor is. As the background art, because some scenes do not need higher processing capability of the processor, and if the processor continuously operates at a higher operation frequency, a larger power consumption burden is brought to the electronic device, and especially for mobile electronic devices such as smart phones sensitive to power consumption, the power consumption directly affects the electric quantity of the mobile electronic devices, so that how to reduce the power consumption of the mobile electronic devices is particularly important, and correspondingly, how to improve the operation frequency of the electronic devices to meet the requirement of the display refresh rate is also important in order to avoid the situation of picture blocking caused by frame dropping. In the related art, an EAS (Energy Aware Scheduling) scheduler implements adjustment of an operating frequency of a processor based on a load condition of a task, where the task is understood as a thread on the processor, a kernel calculates the task load according to an operating time of the task in the processor, and the task load is not associated with a frame time, so that the calculated task load may be higher and may already be in a light-load interaction scenario, and thus, the operating frequency of the processor may still be in a high-frequency situation under the already light-load interaction scenario, but the light-load interaction scenario does not require the processor to maintain high-frequency operation, and therefore, a method for adjusting the operating frequency of the processor based on the load condition of the task has poor real-time performance and a slow down-frequency reaction problem, which is obviously inapplicable to a mobile electronic device sensitive to power consumption.
In view of this, the embodiments of the present disclosure provide a method and an apparatus for adjusting an operating frequency of a processor, and a storage medium.
Fig. 1 is a flowchart illustrating an operating frequency adjustment method of a processor according to an exemplary embodiment, where as shown in fig. 1, the operating frequency adjustment method of the processor may be used in an electronic device of a mobile terminal such as a smartphone and a tablet computer, and includes the following steps.
In step S101, historical consumption resources of the processor are determined, the historical consumption resources being used to characterize resources required by the processor to render a preset number of image frames.
In some embodiments, the processor may be a central processing unit or an image processor, and this embodiment is not limited herein.
It should be noted that the method for adjusting the operating frequency of the processor may be applied to an interaction scene of the electronic device, for example, a heavy-load interaction scene that requires a higher operating frequency of the processor, such as a game interaction scene, a live broadcast scene, and the like; for example, a light-load interaction scene with low running frequency of the processor, such as a web browsing scene and a chat scene, is needed.
It should be noted that rendering is a process of processing the content of an image frame that needs to be displayed on a display. In some embodiments, the duration of rendering a frame by the processor may be understood as the resource consumed by the processor to render a frame, so the historical consumed resource may be a duration resource, and the historical consumed resource may be the actual duration of continuous rendering of the preset number of image frames by the processor, in which case the historical consumed resource of the processor may be determined by: acquiring the actual time length of a processor for continuously rendering a preset number of image frames historically; the actual time duration is determined as a historical consumption resource of the processor.
Illustratively, taking the preset number of image frames as 5 frames, the 5 frames being 5 frames continuously rendered by the processor, and the durations required by the processor to render each frame being duration 1, duration 2, duration 3, duration 4 and duration 5, respectively, in this case, the sum of duration 1, duration 2, duration 3, duration 4 and duration 5 is the actual duration, and the historical consumption resource is the sum of duration 1, duration 2, duration 3, duration 4 and duration 5.
In step S102, a reference refresh resource of the processor-mounted display is determined, where the reference refresh resource is used to represent a resource required by the display to refresh one frame of image.
In some embodiments, the time duration for the display to refresh display of a frame may be understood as the resource required by the display to refresh an image of a frame, and thus, the reference refresh resource may be a time duration resource, and the reference refresh resource may be a reference time duration for the display to refresh an image of a frame, in which case, the reference refresh resource of the processor-mounted display may be determined by: acquiring a current refresh rate; determining a reference time length according to the current refresh rate; the reference duration is determined as a reference refresh resource for a display on which the processor is mounted.
In some embodiments, the current refresh rate of the display is settable. The current refresh rate of the corresponding display may be determined according to the set value. For example, for a game interaction scenario where a higher refresh rate is needed to avoid game interface stuttering, the current refresh rate of the display may be 60 frames/second, which means that the display of the electronic device may refresh 60 new images within 1 second. Illustratively, the reference refresh duration is 1/60, taking as an example that the current refresh rate of the display is 60 frames/second.
In step S103, the operating frequency of the processor is adjusted according to the historical consumed resources and the reference refresh resources.
It should be noted that the processor and the display work together to realize the display of pictures on the screen of the electronic device. The processor renders the frame pictures, and the display is used for refreshing and displaying the frame pictures rendered by the processor on a screen. Generally, the number of frames that can be refreshed in 1 second of the display (i.e., the refresh rate) is related to the number of frames that can be rendered in 1 second by the processor, and the number of frames that can be rendered in 1 second by the processor is related to its own processing capability, and one of the factors that affect the processing capability of the processor may be the operating frequency of the processor. With a constant display resolution, the higher the refresh rate of the display, the higher the processing power requirements of the processor. For example, for a fixed display resolution, a display refresh rate of 30 frames/second requires a higher processing power of the processor, i.e., a higher frequency of operation of the processor, than a display refresh rate of 50 frames/second. In order to satisfy the UI performance of the electronic device and avoid unnecessary power consumption at the same time, it is necessary to match the operating frequency of the processor with the refresh rate of the display, in other words, if the current refresh rate of the display needs to be reached, it is a precondition that the processor is required to render the number of frames of images that match the refresh rate accordingly, for example, if the current refresh rate is 30 frames/second, the processor is required to render 30 frames of images within 1 second. Thus, the operating frequency of the processor may be adjusted according to the refresh rate and the operating frequency.
Based on the above premise, in some embodiments, the historical consumed resource is an actual duration of the processor for continuously rendering a preset number of image frames historically, and the reference refresh resource is a reference duration of the display refreshing one frame of image, in which case, step S103 may include: determining the refresh time for refreshing the preset number of image frames by the display according to the reference time and the preset number of image frames; and adjusting the running frequency of the processor according to the actual time length and the refreshing time length.
It should be noted that the reference time length is a time length required for the display to refresh one frame of image. According to the preset number of image frames and the reference time length, the time length required by the display to refresh the preset number of image frames can be determined.
Since the actual duration and the refresh duration are the durations required for the processor and the display to process the same number of frames, comparing the actual duration and the refresh duration can determine whether the current operating frequency of the processor matches the refresh frequency of the display. The specific comparison method may be: keeping the running frequency of the processor under the condition that the actual duration is equal to the refreshing duration; under the condition that the actual duration is longer than the refreshing duration, the operating frequency of the processor is improved; and reducing the running frequency of the processor under the condition that the actual time length is less than the refreshing time length. Under the condition that the actual duration is equal to the refreshing duration, the running frequency of the representation processor is matched with the refreshing rate of the display, and the running frequency does not need to be adjusted; under the condition that the actual duration is longer than the refreshing duration, the historical frame load borne by the processor is relatively high, and the running frequency of the processor needs to be improved so as to ensure the UI performance and avoid the conditions of frame dropping and the like; under the condition that the actual duration is less than the refreshing duration, the load of the historical frame borne by the processor is low, the running frequency of the processor can be reduced, and the power consumption of the processor is reduced to the maximum extent. It should be noted that the height of the historical frame load represents the size of the resource that needs to be consumed for rendering the preset number of image frames, and the higher the historical frame load is, the larger the resource that needs to be consumed for rendering the preset number of image frames is.
Through the mode, whether the running frequency of the processor is matched with the frame load born by the processor at present is predicted by comparing the actual time length with the refreshing time length, so that the power consumption generated by the processor is reduced while the UI performance is ensured; in addition, whether the operating frequency of the processor is adjusted or not is predicted based on the resources consumed by the processor for rendering the image frame, the purpose of rapidly reducing the operating frequency of the processor can be achieved under the condition that the operating frequency of the processor needs to be reduced, and power consumption is further saved.
In some embodiments, the historical consumed resource is an actual duration for the processor to continuously render a preset number of image frames, and the reference refresh resource is a reference duration for the display to refresh one frame of image, in which case step S103 may include: determining a target frame number according to the actual time length and the reference time length; under the condition that the target frame number is greater than a first frame number and less than a second frame number, maintaining the operating frequency of the processor, wherein the first frame number is less than the second frame number; reducing the operating frequency of the processor under the condition that the target frame number is less than or equal to the first frame number; and increasing the operating frequency of the processor under the condition that the target frame number is greater than or equal to the second frame number.
It should be noted that the target frame number is used to represent the number of frames in the actual duration that the display can refresh the displayed image frames at the current refresh rate. The target frame number may be calculated by:
sum.frame.history＝x*frametime；
the frame is the actual time length, the frame is the reference time length, x is the target frame number, the frame is 1/target _ fps, and the target _ fps is the current refresh rate of the display.
Under the condition that the target frame number is greater than the first frame number and less than the second frame number, the historical frame load of the processor is considered not to be high, and the conditions of frame drop and the like do not occur according to the current refresh rate of the display and the operating frequency of the processor, so the operating frequency of the processor does not need to be adjusted; under the condition that the target frame number is less than or equal to the first frame number, the historical frame load of the processor is considered to be low at the moment, the running frequency of the processor can be reduced at the moment, the processor can meet the current refresh rate with the reduced running frequency, and the situations such as frame dropping and the like cannot occur; when the target frame number is greater than or equal to the second frame number, the historical frame load of the processor is considered to be higher, and the processor is required to have faster processing capacity to achieve the current refresh rate of the display without frame dropping, so that the operating frequency of the processor can be correspondingly improved.
In some embodiments, the first frame number and the second frame number may be set according to an actual situation, and this embodiment is not described herein again.
In some embodiments, the operating frequency of the processor may be set in different steps, and the operating frequency corresponding to each step is different, so that the operating frequency is reduced or increased according to the operating frequency of the different steps. Illustratively, the operating frequency of the processor is set to three levels, which are a1, a2 and A3, wherein the magnitude relation of the operating frequency corresponding to a1, a2 and A3 is: a1> A2> A3, and when the current operating frequency of the processor is the operating frequency corresponding to A2 and the operating frequency of the processor is determined to be reduced, the operating frequency of the processor can be reduced to the operating frequency corresponding to A1; in the case where the current operating frequency of the processor is the operating frequency corresponding to a2 and it is determined to increase the operating frequency of the processor, the operating frequency of the processor may be increased to the operating frequency corresponding to A3.
FIG. 2 is a diagram illustrating an adjustment of an operating frequency of a processor in accordance with an exemplary embodiment. Referring to FIG. 2, in FIG. 2, frame time is the reference duration, target _ fps is the current refresh rate of the display, 4.95 is the first frame number, and 5.31 is the second frame number. The historical frame sequence is that each historical frame rendered by the processor is respectively a serial number 3, a serial number 4, a serial number 7, a serial number 1 and a serial number 6, the historical preset number of image frames is 5 frames which are respectively a serial number 3, a serial number 4, a serial number 7, a serial number 1 and a serial number 6, wherein the serial number 6 can be understood as a frame currently being rendered by the processor, and when the processor processes the image frame of the serial number 6, the actual duration of the frames rendered by the processor including the serial number 6 and the total 5 frames of the serial number 3, the serial number 4, the serial number 7 and the serial number 1 is determined. According to fig. 2, in the case that the ratio of the actual duration to the reference duration is less than or equal to 4.95, the operating frequency of the processor is reduced; under the condition that the ratio of the actual duration to the reference duration is greater than or equal to 5.31, improving the operating frequency of the processor; and keeping the running frequency of the processor unchanged under the condition that the ratio of the actual time length to the reference time length is greater than 4.95 and less than 5.31.
By the method, compared with a comparison method of using the actual time and the refreshing time, the setting of the first frame number and the second frame number can be more refined, so that whether the operating frequency of the processor is adjusted or not can be accurately judged by calculating the target frame number and comparing the target frame number with the first frame number and the second frame number, and the power consumption of the device is saved on the premise of ensuring the UI performance to the maximum extent.
