具体实施方式Detailed ways
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.
首先，需要说明的是，处理器的运行频率的高低表征处理器的处理能力的强弱，处理器的运行频率越高，处理器的处理能力越强。正如背景技术所言，由于某些场景不需要处理器较高的处理能力，而若处理器持续以较高的运行频率工作，将给电子设备带来了较大的功耗负担，特别是对功耗敏感的智能手机等移动类电子设备而言，功耗高低直接影响移动类电子设备的电量，因此，如何降低移动类电子设备的功耗就显得尤其重要，相对应地，为避免出现掉帧造成画面卡顿的情况，如何提高电子设备的运行频率以满足显示器刷新率的需要也至关重要。在相关技术中，EAS(Energy Aware Scheduling，能量感知调度)调度器，是基于任务的负载情况来实现处理器的运行频率的调整，该任务理解为处理器上的线程，内核根据任务在处理器中的运行时间来计算任务负载，没有与帧时间关联，导致计算的任务负载会偏高，此时可能已经处于轻载的交互场景，因此，导致处理器在已经处于轻载的交互场景的情况下运行频率仍会处于高频的情况，但轻载的交互场景无需处理器维持高频运行，因此，基于任务的负载情况来对处理器的运行频率进行调整的方法其实时性差，存在降频反应慢的问题，这对功耗敏感的移动类电子设备而言显然是不适用的。First, it should be noted that the level of the operating frequency of the processor represents the strength of the processing capability of the processor, and the higher the operating frequency of the processor, the stronger the processing capability of the processor. As mentioned in the background art, since some scenarios do not require high processing power of the processor, if the processor continues to work at a high operating frequency, it will bring a greater burden of power consumption to electronic devices, especially for For mobile electronic devices such as smart phones that are sensitive to power consumption, the power consumption directly affects the power of mobile electronic devices. Therefore, how to reduce the power consumption of mobile electronic devices is particularly important. When the frame causes the picture to freeze, how to increase the operating frequency of the electronic device to meet the needs of the display refresh rate is also crucial. In the related art, the EAS (Energy Aware Scheduling, Energy Aware Scheduling) scheduler adjusts the operating frequency of the processor based on the load of the task. The task is understood as a thread on the processor. It is not related to the frame time, resulting in a high computing task load. At this time, it may already be in a light-load interactive scene. Therefore, the processor is already in a light-load interactive scene. The operating frequency will still be at high frequency, but the interactive scenario of light load does not require the processor to maintain high-frequency operation. Therefore, the method of adjusting the operating frequency of the processor based on the task load has poor real-time performance, and there is a frequency reduction. The problem of slow response is obviously not applicable to power-sensitive mobile electronic devices.
有鉴于此，本公开实施例提供了一种处理器的运行频率调整方法、装置及存储介质。In view of this, embodiments of the present disclosure provide a method, a device, and a storage medium for adjusting the operating frequency of a processor.
图1是根据一示例性实施例示出的一种处理器的运行频率调整方法的流程图，如图1所示，该处理器的运行频率调整方法可以用于智能手机、平板电脑等移动类终端的电子设备中，包括以下步骤。FIG. 1 is a flowchart of a method for adjusting the operating frequency of a processor according to an exemplary embodiment. As shown in FIG. 1 , the method for adjusting the operating frequency of a processor can be used for mobile terminals such as smart phones and tablet computers. The electronic equipment includes the following steps.
在步骤S101中，确定处理器的历史消耗资源，历史消耗资源用于表征处理器渲染预设数量图像帧所需要的资源。In step S101, the historical consumption resources of the processor are determined, and the historical consumption resources are used to represent the resources required by the processor to render a preset number of image frames.
在一些实施例中，处理器可以是中央处理器，也可以是图像处理器，本实施例在此不作限定。In some embodiments, the processor may be a central processing unit or an image processor, which is not limited in this embodiment.
需要说明的是，处理器的运行频率调整方法可以应用于电子设备的交互场景，例如需要处理器运行频率较高的重载交互场景，例如游戏交互场景、直播场景等；再例如需要处理器运行频率不高的轻载交互场景，例如网页浏览场景、聊天场景等。It should be noted that the method for adjusting the operating frequency of the processor can be applied to interactive scenarios of electronic devices, such as heavy-duty interactive scenarios that require a high processor operating frequency, such as game interactive scenarios, live broadcast scenarios, etc.; Infrequent light-load interaction scenarios, such as web browsing scenarios, chat scenarios, etc.
应当说明的是，渲染是一种对需要在显示器上进行显示的图像帧的内容进行处理的过程。在一些实施例中，处理器渲染一帧的时长可以理解为处理器渲染一帧所消耗的资源，因此，历史消耗资源可以是一种时长资源，则历史消耗资源可以是处理器历史连续渲染所述预设数量图像帧的实际时长，在此情况下，可以通过以下方式确定处理器的历史消耗资源：获取处理器历史连续渲染预设数量图像帧的实际时长；将实际时长确定为处理器的历史消耗资源。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 can be understood as the resource consumed by the processor to render a frame. Therefore, the historical consumption resource can be a duration resource, and the historical consumption resource can be the historical continuous rendering of the processor. In this case, the historical consumption resources of the processor can be determined in the following ways: obtain the actual duration of the processor’s historical continuous rendering of the preset number of image frames; determine the actual duration as the processor’s actual duration. History consumes resources.
示例地，以预设数量图像帧是5帧，该5帧为处理器连续渲染的5帧，且处理器渲染每帧所需要的时长分别为时长1、时长2、时长3、时长4和时长5为例，在此情况下，时长1、时长2、时长3、时长4和时长5之和为实际时长，则历史消耗资源为时长1、时长2、时长3、时长4和时长5之和。For example, the preset number of image frames is 5 frames, the 5 frames are 5 frames continuously rendered by the processor, and the duration required by the processor to render each frame is
在步骤S102中，确定搭载处理器的显示器的基准刷新资源，基准刷新资源用于表征显示器刷新一帧图像所需要的资源。In step S102, a reference refresh resource of the display equipped with the processor is determined, and the reference refresh resource is used to represent the resource required by the display to refresh one frame of image.
在一些实施例中，显示器刷新显示一帧的时长可以理解为显示器刷新一帧图像所需要的资源，因此，基准刷新资源可以是一种时长资源，则基准刷新资源可以是显示器刷新一帧图像的基准时长，在此情况下，可以通过以下方式确定搭载处理器的显示器的基准刷新资源：获取当前刷新率；根据当前刷新率，确定基准时长；将基准时长确定为搭载处理器的显示器的基准刷新资源。In some embodiments, the duration for the display to refresh and display one frame can be understood as the resources required by the display to refresh one frame of image. Therefore, the reference refresh resource may be a duration resource, and the reference refresh resource may be the time for the display to refresh one frame of image. The benchmark duration, in this case, the benchmark refresh resource of the display equipped with the processor can be determined in the following ways: obtain the current refresh rate; determine the benchmark duration according to the current refresh rate; determine the benchmark duration as the benchmark refresh of the display equipped with the processor resource.
在一些实施例中，显示器的当前刷新率是可以设置的。根据设置的值可以确定相应的显示器的当前刷新率。示例地，对于游戏交互场景而言，需要较高的刷新率以避免游戏界面卡顿，显示器的当前刷新率可以是60帧/秒，其表示电子设备的显示器在1秒钟内可以刷新显示60次新图像。示例地，以显示器的当前刷新率是60帧/秒为例，基准刷新时长为1/60。In some embodiments, the current refresh rate of the display can be set. The current refresh rate of the corresponding display can be determined according to the set value. For example, for a game interaction scenario, a higher refresh rate is required to avoid the game interface being stuck, and the current refresh rate of the display may be 60 frames/second, which means that the display of the electronic device can refresh the display for 60 frames per second. next new image. For example, taking the current refresh rate of the display as 60 frames/second as an example, the reference refresh duration is 1/60.
在步骤S103中，根据历史消耗资源和基准刷新资源，调整处理器的运行频率。In step S103, the operating frequency of the processor is adjusted according to historical consumption resources and benchmark refresh resources.
需要说明的是，处理器和显示器联合工作以实现在电子设备的屏幕上进行画面显示。处理器进行帧画面的渲染，显示器用于将处理器渲染的帧画面刷新显示在屏幕上。一般来讲，显示器1秒中能够刷新显示的帧画面数量(即刷新率)与处理器在1秒钟能够渲染帧画面数量有关，而处理器在1秒钟能够渲染帧画面数量与其自身处理能力有关，进而影响处理器的处理能力的因素之一可以是处理器的运行频率。在显示分辨率不变的情况下，显示器的刷新率越高，对处理器的处理能力要求也就越高。示例地，对于一固定的显示分辨率，显示器刷新率要达到30帧/秒与显示器刷新率要达到50帧/秒相比较而言，显示器刷新率要达到50帧/秒需要处理器的处理能力更高，也即是需要处理器的运行频率更高。为了同时满足电子设备的UI性能和避免不必要的功耗，需要使处理器的运行频率与显示器的刷新率相匹配，换而言之，若需要达到显示器当前的刷新率，则前提是需要处理器相应地渲染好与该刷新率匹配的图像帧数，例如，若当前刷新率为30帧/秒，则需要处理器在1秒钟内渲染好30帧图像。因此，可以根据刷新率和运行频率来调整处理器的运行频率。It should be noted that, the processor and the display work together to realize picture display on the screen of the electronic device. The processor performs frame rendering, and the display is used to refresh and display the frame rendered by the processor on the screen. Generally speaking, the number of frames that the display can refresh and display in 1 second (that is, the refresh rate) is related to the number of frames that the processor can render in 1 second, and the number of frames that the processor can render in 1 second is related to its own processing capacity. One of the factors that, in turn, affects the processing power of the processor may be the operating frequency of the processor. Under the condition that the display resolution remains unchanged, 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 per second is compared to a display refresh rate of 50 frames per second, which requires processor processing power to achieve a display refresh rate of 50 frames per second. Higher, that is, requires the processor to run at a higher frequency. In order to meet the UI performance of electronic devices 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. The processor renders the number of image frames that match the refresh rate accordingly. For example, if the current refresh rate is 30 frames per second, the processor needs to render 30 frames of images within 1 second. Therefore, the operating frequency of the processor can be adjusted according to the refresh rate and operating frequency.
基于上述前提，在一些实施例中，历史消耗资源为处理器历史连续渲染预设数量图像帧的实际时长，基准刷新资源为显示器刷新一帧图像的基准时长，在此情况下，步骤S103可以包括：根据基准时长和预设数量图像帧，确定显示器刷新预设数量图像帧的刷新时长；根据实际时长和刷新时长，调整处理器的运行频率。Based on the above premise, in some embodiments, the historical consumption resource is the actual duration for the processor to continuously render a preset number of image frames in history, and the reference refresh resource is the reference duration for the display to refresh one frame of image. In this case, step S103 may include: : Determine the refresh duration for the display to refresh the preset number of image frames according to the reference duration and the preset number of image frames; adjust the running frequency of the processor according to the actual duration and the refresh duration.
需要说明的是，基准时长是显示器刷新一帧图像所需要的时长。根据预设数量图像帧和基准时长，可以确定显示器刷新预设数量图像帧所需要的时长。It should be noted that the reference duration is the duration required for the display to refresh one frame of image. According to the preset number of image frames and the reference duration, the duration required for the display to refresh the preset number of image frames can be determined.
由于实际时长和刷新时长是处理器和显示器处理相同帧数的所需要的时长，因此，对实际时长和刷新时长进行对比，可以确定处理器当前的运行频率是否与显示器的刷新频率相匹配。具体的对比方式可以是：在实际时长等于刷新时长的情况下，保持处理器的运行频率；在实际时长大于刷新时长的情况下，提高处理器的运行频率；在实际时长小于刷新时长的情况下，降低处理器的运行频率。在实际时长等于刷新时长的情况下，表征处理器的运行频率与显示器的刷新率相匹配，运行频率无需调整；在实际时长大于刷新时长的情况下，表明处理器的承担的历史帧负载偏高，需要提高处理器的运行频率，以确保UI性能，避免掉帧等情况；在实际时长小于刷新时长的情况下，表明处理器的承担的历史帧负载偏低，可以降低处理器的运行频率，以最大程度降低处理器的功耗。需要说明的是，历史帧负载的高低表征渲染预设数量图像帧所需要消耗的资源的大小，历史帧负载越高，渲染预设数量图像帧所需要消耗的资源的越大。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, by comparing the actual duration and the refresh duration, it can be determined whether the current operating frequency of the processor matches the refresh frequency of the display. The specific comparison method can be: when the actual duration is equal to the refresh duration, keep the running frequency of the processor; when the actual duration is greater than the refresh duration, increase the running frequency of the processor; when the actual duration is less than the refresh duration , reduce the operating frequency of the processor. When the actual duration is equal to the refresh duration, it means that the running frequency of the processor matches the refresh rate of the display, and the running frequency does not need to be adjusted; when the actual duration is greater than the refresh duration, it indicates that the historical frame load borne by the processor is too high , it is necessary to increase the running frequency of the processor to ensure UI performance and avoid dropped frames; if the actual duration is less than the refresh duration, it indicates that the historical frame load borne by the processor is low, and the running frequency of the processor can be reduced. to minimize the power consumption of the processor. It should be noted that the level of the historical frame load represents the size of the resources needed to render the preset number of image frames. The higher the historical frame load, the greater the resources needed to render the preset number of image frames.
通过上述方式，通过比较实际时长和刷新时长的大小，来预测处理器的运行频率与处理器目前所承担的帧负载是否相匹配，以在确保UI性能的同时降低处理器产生的功耗；此外，基于处理器渲染图像帧所消耗的资源来预测是否调整处理器的运行频率，可以在需要降低处理器的运行频率的情况下实现快速降低处理器的运行频率的目的，进一步节省功耗。Through the above method, by comparing the actual duration and the refresh duration, it is predicted whether the running frequency of the processor matches the frame load currently borne by the processor, so as to reduce the power consumption generated by the processor while ensuring UI performance; , predicting whether to adjust the running frequency of the processor based on the resources consumed by the processor to render the image frame, can achieve the purpose of rapidly reducing the running frequency of the processor and further save power consumption when the running frequency of the processor needs to be reduced.
在一些实施例中，历史消耗资源为处理器历史连续渲染预设数量图像帧的实际时长，基准刷新资源为显示器刷新一帧图像的基准时长，在此情况下，步骤S103可以包括：根据实际时长和基准时长，确定目标帧数；在目标帧数大于第一帧数且小于第二帧数的情况下，保持处理器的运行频率，其中，第一帧数小于第二帧数；在目标帧数小于或等于第一帧数的情况下，降低处理器的运行频率；在目标帧数大于或等于第二帧数的情况下，提高处理器的运行频率。In some embodiments, the historical consumption resource is the actual duration for the processor to continuously render a preset number of image frames in history, and the reference refresh resource is the reference duration for the display to refresh one frame of image. In this case, step S103 may include: according to the actual duration and the reference duration to determine the target frame number; when the target frame number is greater than the first frame number and less than the second frame number, keep the running frequency of the processor, where the first frame number is less than the second frame number; When the number of frames is less than or equal to the first number of frames, the operating frequency of the processor is reduced; when the number of target frames is greater than or equal to the second number of frames, the operating frequency of the processor is increased.
需要说明的是，目标帧数用于表征在实际时长内显示器在当前刷新率下能够刷新显示的图像帧的帧数。目标帧数可以通过下式计算：It should be noted that the target frame number is used to represent the frame number of image frames that the display can refresh and display at the current refresh rate within the actual duration. The target frame number can be calculated by the following formula:
sum.frame.history＝x*frametime；sum.frame.history = x*frametime;
其中，sum.frame.history为实际时长，frametime为基准时长，x为目标帧数，frametime＝1/target_fps，target_fps为显示器的当前刷新率。Wherein, sum.frame.history is the actual duration, frametime is the reference duration, x is the target frame number, frametime=1/target_fps, and target_fps is the current refresh rate of the display.
在目标帧数大于第一帧数且小于第二帧数的情况下，此时认为处理器的历史帧负载不高，且依据显示器的当前刷新率和处理器的运行频率不会出现掉帧等情况，因此无需调整处理器的运行频率；在目标帧数小于等于第一帧数的情况下，此时认为处理器的历史帧负载偏低，此时可以降低处理器的运行频率，处理器以降低后的运行频率也可以满足当前刷新率，不会出现掉帧等情况；在目标帧数大于等于第二帧数的情况下，此时认为处理器的历史帧负载偏高，为达到显示器的当前刷新率，不出现掉帧的情况，需要处理器能具备更快的处理能力，则相应地可以提高处理器的运行频率。When the target frame number is greater than the first frame number and less than the second frame number, it is considered that the historical frame load of the processor is not high, and there will be no frame drop according to the current refresh rate of the display and the operating frequency of the processor, etc. Therefore, there is no need to adjust the running frequency of the processor; if 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 this time, and the running frequency of the processor can be reduced at this time. The reduced operating frequency can also meet the current refresh rate, and there will be no frame drop. At the current refresh rate, there is no frame drop, and the processor needs to have faster processing capabilities, so the operating frequency of the processor can be increased accordingly.
在一些实施例中，第一帧数和第二帧数可以根据实际情况进行设定，本实施例在此不做赘述。In some embodiments, the first number of frames and the second number of frames may be set according to actual conditions, which will not be repeated in this embodiment.
在一些实施例中，可以设置处理器不同档次的运行频率，每个档次对应的运行频率是不同的，根据不同档次的运行频率实现运行频率的降低或提高。示例地，处理器的运行频率设置有三个档次，分别为A1、A2和A3，其中，A1、A2和A3对应的运行频率的大小关系为：A1>A2>A3，在处理器当前的运行频率为A2对应的运行频率且在确定降低处理器的运行频率的情况下，可以将处理器的运行频率降低为A1对应的运行频率；在处理器当前的运行频率为A2对应的运行频率且在确定提高处理器的运行频率的情况下，可以将处理器的运行频率提高为A3对应的运行频率。In some embodiments, the operating frequencies of different grades of the processor can be set, the operating frequencies corresponding to each grade are different, and the operating frequencies can be reduced or increased according to the operating frequencies of different grades. For example, the operating frequency of the processor is set to three grades, which are A1, A2, and A3, respectively. The relationship between the operating frequencies corresponding to A1, A2, and A3 is: A1>A2>A3. At the current operating frequency of the processor It is the operating frequency corresponding to A2 and in the case of determining to reduce the operating frequency of the processor, the operating frequency of the processor can be reduced to the operating frequency corresponding to A1; when the current operating frequency of the processor is the operating frequency corresponding to A2 and after determining In the case of increasing the operating frequency of the processor, the operating frequency of the processor can be increased to the operating frequency corresponding to the A3.
图2是根据一示例性实施例示出的一种调整处理器的运行频率的示意图。参照图2，在图2中，frametime为基准时长，target_fps为显示器的当前刷新率，4.95为第一帧数，5.31为第二帧数。历史帧序列为处理器渲染的各历史帧，分别为序号3、序号3、序号4、序号7、序号1和序号6，历史预设数量图像帧为5帧，分别为序号3、序号4、序号7、序号1和序号6，其中序号6可以理解为处理器当前正在渲染的帧，在处理器处理序号6的图像帧时，确定处理器渲染的包括序号6在内以及序号3、序号4、序号7、序号1共5帧的实际时长。根据图2所示，在实际时长与基准时长的比值小于等于4.95的情况下，降低处理器的运行频率；在实际时长与基准时长的比值大于等于5.31的情况下，提高处理器的运行频率；在实际时长与基准时长的比值大于4.95且小于5.31的情况下，保持处理器的运行频率不变。Fig. 2 is a schematic diagram of adjusting the operating frequency of a processor according to an exemplary embodiment. Referring to FIG. 2 , in FIG. 2 , frametime 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 each historical frame rendered by the processor, which are
通过上述方式，相较于利用实际时长与刷新时长的比较方式而言，由于第一帧数和第二帧数的设置可以做到更为精细化，因此，通过计算目标帧数，并与第一帧数和第二帧数相比较的方式，可以准确判断是否调整处理器的运行频率，以此在最大程度确保UI性能的前提下节省设备功耗。Through the above method, compared with the comparison method using the actual duration and the refresh duration, the setting of the first frame number and the second frame number can be more refined. Therefore, by calculating the target frame number and comparing it with the first frame number By comparing the number of one frame with the number of second frames, it can be accurately determined whether to adjust the operating frequency of the processor, so as to save the power consumption of the device on the premise of ensuring the UI performance to the greatest extent.
