随着电子技术的发展，电子设备的功能不断增强，电子设备越来越频繁的参与到消费者的日常生活中来。其中，以可穿戴电子设备为代表的电子设备，由于消费者的使用***板等电子设备不同，需要可穿戴电子设备具有更强的续航能力。With the development of electronic technology, the functions of electronic devices continue to increase, and electronic devices are increasingly involved in consumers' daily lives. Among them, electronic devices represented by wearable electronic devices need to have stronger battery life because consumers' usage habits, product forms and product uses are different from electronic devices such as mobile phones and tablets.
在电子设备上的电池容量不变的情况下，可以通过降低电子设备的功耗可以提升电子设备的续航能力。一种降低电子设备的功耗的方法为，根据当前运行的任务、负载等多种参数确定需要调用哪种类型的核心(如麒麟9000的一个A77大核、三个A77中核、四个A55小核)，以及调用核心的数量，进而通过降低CPU的功耗以降低电子设备的功耗。其中，不同核心的能耗曲线不同。例如，在浏览新闻等低负载场景中，电子设备主要调用中核和小核；在游戏等高负载场景中，电子设备会调用大核，进而在不降低用户体验的情况下降低电子设备的功耗。When the battery capacity of the electronic device remains unchanged, the battery life of the electronic device can be improved by reducing the power consumption of the electronic device. One way to reduce the power consumption of electronic equipment is to determine which type of core needs to be called based on the currently running tasks, load and other parameters (such as one A77 large core, three A77 medium cores, four A55 small cores of Kirin 9000). cores), and the number of calling cores, thereby reducing the power consumption of electronic devices by reducing the power consumption of the CPU. Among them, the energy consumption curves of different cores are different. For example, in low-load scenarios such as browsing news, electronic devices mainly use medium cores and small cores; in high-load scenarios such as gaming, electronic devices will use large cores, thereby reducing the power consumption of electronic devices without reducing user experience. .
但是，该方法主要依赖于CPU的架构，在许多电子设备上并不能取得比较好的效果。例如，在电子设备为搭载多个能效相同或相近核心的CPU的电子设备，或者，电子设备为嵌入式类型的电子设备的情况下，该方法的收益较小。However, this method mainly relies on the architecture of the CPU and cannot achieve better results on many electronic devices. For example, when the electronic device is an electronic device equipped with multiple CPUs with the same or similar energy efficiency cores, or the electronic device is an embedded type electronic device, the benefits of this method are smaller.

首先，由于消费者对如手表、手环等可穿戴电子设备的使用***板等电子设备一样，总是每天对电子设备充电；其次，相比于手机、平板等电子设备，可穿戴电子设备的电池容量一般较小。为了尽可能的提升用户的体验，应该在不影响用户的体验和可穿戴电子设备的功能正常运行的情况下，尽可能的降低可穿戴电子设备的功耗。First of all, because consumers’ usage habits of wearable electronic devices such as watches and bracelets are not the same as those of electronic devices such as mobile phones and tablets, they always charge electronic devices every day; secondly, compared with electronic devices such as mobile phones and tablets, Wearable electronic devices generally have smaller battery capacities. In order to improve the user experience as much as possible, the power consumption of wearable electronic devices should be reduced as much as possible without affecting the user experience and the normal operation of the wearable electronic devices.
一种可行的降低电子设备的功耗的方法为：操作***根据当前运行的任务、CPU负载等多种参数配置CPU的电压(工作电压)和/或频率(工作频率)，如图1所示。A feasible method to reduce the power consumption of electronic equipment is: the operating system configures the voltage (working voltage) and/or frequency (working frequency) of the CPU according to the currently running tasks, CPU load and other parameters, as shown in Figure 1 .
图1为本申请实施例提供的降低电子设备的功耗的方法的一个示例性示意图。 FIG. 1 is an exemplary schematic diagram of a method for reducing power consumption of an electronic device provided by an embodiment of the present application.
电子设备根据当前运行的业务的类型，配置CPU频率为不同的频率，进而兼顾电子设备的性能和功耗。如图1所示，当电子设备运行第一类型业务时，CPU频率最低；其次，当电子设备运行第二类型业务时，CPU频率次低；再次，当电子设备运行第三类型业务时，CPU频率较高；当电子设备运行第四类型业务时，CPU频率最高。其中，第一类型业务的负载低于第二类型业务的负载，第二类型业务的负载低于第三类型业务的负载；第三类型业务的负载低于第四类型业务的负载。The electronic device configures the CPU frequency to different frequencies according to the type of business currently running, thereby taking into account the performance and power consumption of the electronic device. As shown in Figure 1, when the electronic device runs the first type of business, the CPU frequency is the lowest; secondly, when the electronic device runs the second type of business, the CPU frequency is the second lowest; thirdly, when the electronic device runs the third type of business, the CPU frequency The frequency is higher; when the electronic device is running the fourth type of business, the CPU frequency is the highest. Among them, the load of the first type of service is lower than the load of the second type of service, the load of the second type of service is lower than the load of the third type of service, and the load of the third type of service is lower than the load of the fourth type of service.
其中，对于基于Linux内核的操作***来讲，可以基于Linux内核中的CPUfreq模块调整CPU的电压和频率。其中，CPUfreq模块提供许多种调度策略，例如Performance策略、Powersave策略、Userspace策略、Ondemand策略等。其中，Userspace策略允许操作***自己调整CPU的电压和频率，进而实现如图1所示的方法。Among them, for operating systems based on the Linux kernel, the voltage and frequency of the CPU can be adjusted based on the CPUfreq module in the Linux kernel. Among them, the CPUfreq module provides many scheduling strategies, such as Performance strategy, Powersave strategy, Userspace strategy, Ondemand strategy, etc. Among them, the Userspace policy allows the operating system to adjust the voltage and frequency of the CPU by itself, thereby implementing the method shown in Figure 1.
但是，对于以可穿戴电子设备为代表的电子设备来说，电子设备上可以运行的高负载的业务较少，电子设备运行该高负载的业务的时间也较少，大部分业务的负载差距不大，如图2所示。However, for electronic devices represented by wearable electronic devices, there are fewer high-load services that can be run on the electronic devices, and the electronic devices have less time to run the high-load services. The load gap of most services is not large. Large, as shown in Figure 2.
图2为本申请实施例提供的降低电子设备的功耗的方法的另一个示例性示意图。FIG. 2 is another exemplary schematic diagram of a method for reducing power consumption of an electronic device provided by an embodiment of the present application.
如图2所示，当电子设备上不同类型业务的负载差距不大的情况下，不同类型业务对应的CPU频率差距不大。其次，在消费者日常生活中，电子设备更多处于低负载状态，即电子设备高负载业务的运行时间较短。As shown in Figure 2, when the load difference between different types of services on the electronic device is not large, the difference in CPU frequencies corresponding to different types of services is not large. Secondly, in consumers' daily lives, electronic equipment is more likely to be in a low-load state, that is, the operation time of high-load services of electronic equipment is shorter.
在图2所示的情况下，电子设备根据当前运行的业务的类型，配置CPU频率为不同的频率的这种方法取得的功耗收益较小，不能有效的降低功耗，或者说图1所示的方法取得的功耗收益仍然不足以满足消费者的需求。In the situation shown in Figure 2, the electronic device configures the CPU frequency to different frequencies according to the type of business currently running. This method achieves small power consumption benefits and cannot effectively reduce power consumption. In other words, as shown in Figure 1 The power consumption gains obtained by the method shown are still not enough to meet the needs of consumers.
基于此，本申请实施例提供了调整设备功耗的方法及电子设备。本申请提供的调整设备功耗的方法基于操作***的中断处理能力，将被中断唤醒后的CPU的处理过程分为至少两个阶段，分别为唤醒阶段和业务处理阶段；在唤醒阶段，电子设备的操作***配置CPU的频率和/或电压为较低的水平，进而降低功耗；在业务处理阶段，电子设备上的操作***可以基于业务的类型配置CPU的频率和/或电压，或者，配置CPU的频率和/或电压为较高的水平，进而保障用户的体验。Based on this, embodiments of the present application provide methods and electronic devices for adjusting device power consumption. The method for adjusting device power consumption provided by this application is based on the interrupt processing capability of the operating system. The processing process of the CPU after being awakened by an interrupt is divided into at least two stages, namely the wake-up stage and the business processing stage; during the wake-up stage, the electronic device The operating system configures the frequency and/or voltage of the CPU to a lower level, thereby reducing power consumption; during the business processing stage, the operating system on the electronic device can configure the frequency and/or voltage of the CPU based on the type of business, or configure The CPU frequency and/or voltage are at a higher level to ensure user experience.
值得说明的是，本申请实施例提供的调整设备功耗的方法可以作用于电子设备上的CPU，也可以作用于电子设备内部的其他芯片或处理单元，例如，数字信号处理器(digital signal processor，DSP)、神经网络处理器(neural-network processing unit，NPU)等可以接收中断并且可以被配置不同的工作电压和/或工作频率的芯片或处理单元。其中，处理器也可以包括DSP、CPU、NPU中的一种或多种，即处理器作为一个芯片集成了DSP、NPU、CPU中的一种或多种。It is worth noting that the method for adjusting device power consumption provided by the embodiments of the present application can be applied to the CPU on the electronic device, or to other chips or processing units inside the electronic device, such as a digital signal processor (digital signal processor). , DSP), neural-network processing unit (NPU) and other chips or processing units that can receive interrupts and can be configured with different operating voltages and/or operating frequencies. The processor may also include one or more of DSP, CPU, and NPU, that is, the processor integrates one or more of DSP, NPU, and CPU as a chip.
在后文中，主要以CPU为例介绍本申请实施例提供的调整设备功耗的方法。In the following, the method of adjusting device power consumption provided by the embodiments of the present application will be mainly introduced using the CPU as an example.
其中，在唤醒阶段，CPU几乎不工作，开放时钟等能力给直接内存访问(Direct Memorty Access，DMA)引擎(或DMA芯片、或DMA控制器)，使得DMA引擎可以将数据获取装置(如外设、传感器、网卡)(也可以称为数据获取装置)的数据读入到内存中。其中，内存可以包括集成在CPU内部的L1内存、L2内存、L3内存，和/或也可以包括电子设备的内存。Among them, during the wake-up phase, the CPU hardly works and opens clock and other capabilities to the Direct Memory Access (DMA) engine (or DMA chip, or DMA controller), so that the DMA engine can obtain data from devices (such as peripherals). , sensor, network card) (also called a data acquisition device), the data is read into the memory. Among them, the memory may include L1 memory, L2 memory, and L3 memory integrated inside the CPU, and/or may also include memory of electronic devices.
可选地，在本申请一些实施例中，在唤醒阶段，电子设备可以为业务处理阶段做一些预先准备，例如，初始化一些内部参数等，在此不做限定。Optionally, in some embodiments of the present application, during the wake-up phase, the electronic device can make some pre-preparations for the business processing phase, such as initializing some internal parameters, etc., which are not limited here.
其中，在业务处理阶段，CPU按照上层业务的逻辑处理内存中的数据，通过计算得到结果。Among them, in the business processing stage, the CPU processes the data in the memory according to the logic of the upper-layer business and obtains the results through calculation.
值得说明的是，在唤醒阶段，由于DMA引擎还没有将全部的数据读入到内存中，CPU此时可以不处理数据。It is worth mentioning that during the wake-up phase, since the DMA engine has not read all the data into the memory, the CPU does not need to process the data at this time.
可以理解的是，相比于图1所示的方法，本申请实施例提供的调整设备功耗的方法，由于在更小的粒度上发现了CPU在空负载维持较高频率和/或电压的问题，进而通过降低CPU空负载情况下的频率和/或电压，降低电子设备的功耗。It can be understood that, compared with the method shown in Figure 1, the method of adjusting device power consumption provided by the embodiment of the present application has been found at a smaller granularity that the CPU maintains a higher frequency and/or voltage under no load. problem, thereby reducing the power consumption of electronic devices by reducing the frequency and/or voltage of the CPU under no load conditions.
下面首先以电子设备为手表和手环为例，示例性的介绍本申请实施例提供的调整设备功耗的方法。The following first takes the electronic device as a watch and a bracelet as an example to exemplarily introduce the method for adjusting the power consumption of the device provided by the embodiment of the present application.
图3A为本申请实施例提供的调整设备功耗方法的场景的一个示例性示意图。FIG. 3A is an exemplary schematic diagram of a scenario of a method for adjusting device power consumption provided by an embodiment of the present application.
如图3A所示，手表收到网络发送的第一消息，并将消息在屏幕上显示出来的过程可以分为四个阶段。As shown in Figure 3A, the process of the watch receiving the first message sent by the network and displaying the message on the screen can be divided into four stages.
阶段1：手表的屏幕可以不显示任何内容，处于息屏状态。手表1通过蓝牙、WiFi等近场无线通信技术与互联网连接，或者可以通过蜂窝移动通信与互联网连接，在此不做限定。或者，手表也可以显示一些内容，如时间等。Stage 1: The screen of the watch can be in a screen-off state without displaying any content. Watch 1 is connected to the Internet through near-field wireless communication technologies such as Bluetooth and WiFi, or can be connected to the Internet through cellular mobile communications, which is not limited here. Alternatively, the watch can also display some content, such as time.
阶段2：手表接收到来自网络中的服务器发送的消息。其中，手表通过网卡接收数据，并将数据存储到网卡中。可选地，在本申请一些实施例中，手表可以通过蓝牙硬件模块或WiFi硬件模块接收数据。 Phase 2: The watch receives the message sent from the server in the network. Among them, the watch receives data through the network card and stores the data into the network card. Optionally, in some embodiments of the present application, the watch can receive data through a Bluetooth hardware module or a WiFi hardware module.
阶段3：手表的网卡接收到数据后，向操作***发送中断，唤醒CPU；同时，DMA引擎将数据从网卡拷贝到内存中。Stage 3: After the watch's network card receives the data, it sends an interrupt to the operating system and wakes up the CPU; at the same time, the DMA engine copies the data from the network card to the memory.
阶段4：CPU处理该拷贝到内存中的数据；在CPU按照上层业务的逻辑处理数据完成后，电子设备点亮屏幕，并对应的显示消息的内容。Stage 4: The CPU processes the data copied to the memory; after the CPU completes processing the data according to the logic of the upper-layer business, the electronic device lights up the screen and displays the content of the message accordingly.
图3B为本申请实施例提供的图3A所示场景中不同阶段对应不同CPU阶段的一个示例性示意图。FIG. 3B is an exemplary schematic diagram of different stages corresponding to different CPU stages in the scenario shown in FIG. 3A provided by an embodiment of the present application.
如图3B所示，阶段1和阶段2可以对应于休眠阶段；阶段3对应于唤醒阶段；阶段4对应于业务处理阶段。As shown in Figure 3B, Phase 1 and Phase 2 may correspond to the sleep phase; Phase 3 corresponds to the wake-up phase; and Phase 4 corresponds to the service processing phase.
其中，在休眠阶段，CPU的频率最低，为A1Hz；在唤醒阶段，CPU频率为A2Hz；在业务处理阶段，CPU的频率最高，频率为A3Hz。其中，A1小于等于A2，A2小于A3。其中，休眠阶段也可以称为休眠模式、休眠状态，例如部分CPU可以通过WFI(wait for interrupt)指令和WFE(wait for event)指令进入休眠阶段。Among them, in the sleep stage, the CPU frequency is the lowest, A1Hz; in the wake-up stage, the CPU frequency is A2Hz; in the business processing stage, the CPU frequency is the highest, A3Hz. Among them, A1 is less than or equal to A2, and A2 is less than A3. Among them, the sleep stage can also be called sleep mode and sleep state. For example, some CPUs can enter the sleep stage through the WFI (wait for interrupt) instruction and the WFE (wait for event) instruction.
值得说明的是，A2等于A1的情况下，唤醒阶段可以认为与休眠阶段相同，即在CPU处于休眠阶段的情况下，电子设备上的DMA引擎仍然可以正常工作；在该情况下，可以认为本申请调整设备功耗的方法实质上是延长了CPU的休眠阶段的时间，处于休眠阶段的CPU不会被数据获取装置发送的中断唤醒，而是被DMA引擎的中断唤醒，其中DMA引擎的中断用于通知CPU数据已经拷贝完成。It is worth noting that when A2 is equal to A1, the wake-up phase can be considered the same as the sleep phase, that is, when the CPU is in the sleep phase, the DMA engine on the electronic device can still work normally; in this case, the wake-up phase can be considered to be the same as the sleep phase. The method of applying to adjust device power consumption essentially prolongs the sleep phase of the CPU. The CPU in the sleep phase will not be awakened by the interrupt sent by the data acquisition device, but by the interrupt of the DMA engine. The interrupt of the DMA engine is used. Notifies the CPU that the data has been copied.
可选地，在本申请一些实施例中，A3可以是变量，即A3可以根据当前业务的类型配置为具体的不同数值。A3的确定方法可以参考图1所示的内容，此处不再赘述。Optionally, in some embodiments of the present application, A3 may be a variable, that is, A3 may be configured with different specific values according to the type of the current service. The determination method of A3 can refer to the content shown in Figure 1 and will not be described again here.
值得说明的是，CPU的电压在不同CPU阶段的电压变化趋势可以与图3B所示的内容类似。It is worth noting that the voltage change trend of the CPU voltage in different CPU stages can be similar to what is shown in Figure 3B.
可选地，在本申请一些实施例中，阶段1和阶段2可以对应于其他CPU阶段，在此不做限定。例如，阶段1和阶段2可以对应于不同的CPU阶段；又例如，阶段1和阶段2可以对应于业务处理阶段等。Optionally, in some embodiments of the present application, stage 1 and stage 2 may correspond to other CPU stages, which are not limited here. For example, phase 1 and phase 2 may correspond to different CPU phases; for another example, phase 1 and phase 2 may correspond to business processing phases, etc.

阶段2：响应于接收到用户的操作后，电子设备开始执行心率检测；或者，周期性的，电子设备执行心率检测。电子设备在执行心率检测的过程中，通过光电传感器记录手腕反射的光的强度变化。Phase 2: In response to receiving the user's operation, the electronic device begins to perform heart rate detection; or, periodically, the electronic device performs heart rate detection. During the process of performing heart rate detection, the electronic device records the intensity changes of the light reflected by the wrist through the photoelectric sensor.
可选地，在本申请一些实施例中，电子设备也可以通过其他硬件模块以其他方式执行心率检测。Optionally, in some embodiments of the present application, the electronic device can also perform heart rate detection in other ways through other hardware modules.
阶段3：在心率检测完成后，或者，在心率检测的过程中手环通过DMA引擎将数据从光电传感器拷贝到内存中。Stage 3: After the heart rate detection is completed, or during the heart rate detection process, the bracelet copies the data from the photoelectric sensor to the memory through the DMA engine.
阶段4：CPU基于记录的光的强度或其他参数的变化，基于光体积变化描记法或者其他方法、算法，计算得到心率，并将心率的数据显示在手环的显示屏上。如图4A所示，电子设备将心率90显示在手环的显示屏上。Stage 4: The CPU calculates the heart rate based on the recorded changes in light intensity or other parameters, based on photoplethysmography or other methods and algorithms, and displays the heart rate data on the display of the bracelet. As shown in Figure 4A, the electronic device displays the heart rate 90 on the display screen of the bracelet.

其中，在休眠阶段，CPU的频率最低，为B1Hz；在唤醒阶段，CPU频率为B2Hz；在业务处理阶段，CPU的频率最高，频率为A3Hz。其中，B1小于等于B2，B2小于B3。Among them, during the sleep phase, the CPU frequency is the lowest, which is B1Hz; during the wake-up phase, the CPU frequency is B2Hz; during the business processing phase, the CPU frequency is the highest, which is A3Hz. Among them, B1 is less than or equal to B2, and B2 is less than B3.
值得说明的是，CPU的电压在不同CPU阶段的电压变化趋势可以与图3B所示的内容类似。It is worth noting that the voltage change trend of the CPU voltage in different CPU stages can be similar to what is shown in Figure 3B.
可选地，在本申请一些实施例中，阶段2可以对应于其他CPU阶段，在此不做限定。例如，阶段2可以对应于业务处理阶段等。Optionally, in some embodiments of the present application, stage 2 may correspond to other CPU stages, which is not limited here. For example, phase 2 may correspond to a business processing phase, etc.
结合图3A、图3B、图4A和图4B所示的内容，可以得出，首先，本申请实施例提供的调整设备功耗的方法，将CPU阶段划分为至少两个阶段，其中至少两个阶段包括唤醒阶段；其次，本申请实施例提供的调整设备功耗的方法，通过降低唤醒阶段的CPU的频率或电压，进而降低电子设备的功耗。Combining the contents shown in Figure 3A, Figure 3B, Figure 4A and Figure 4B, it can be concluded that first, the method for adjusting device power consumption provided by the embodiment of the present application divides the CPU stage into at least two stages, of which at least two The stages include a wake-up stage; secondly, the method for adjusting the power consumption of a device provided by embodiments of the present application reduces the power consumption of the electronic device by reducing the frequency or voltage of the CPU in the wake-up stage.
值得说明的是，图1和图2所示的方法，同样可以应用在图3A、图3B、图4A和图4B中阶段4时CPU的频率调整。即，本申请实施例提供的降低电子设备功耗的方法在图1和图2所示的方法的基础上，进一步降低电子设备的功耗，延长电子设备的续航时间，进而提升用户的体验。It is worth noting that the methods shown in Figures 1 and 2 can also be applied to the frequency adjustment of the CPU in stage 4 in Figures 3A, 3B, 4A and 4B. That is, the method for reducing the power consumption of electronic equipment provided by the embodiments of the present application is based on the methods shown in Figures 1 and 2, further reducing the power consumption of the electronic equipment, extending the battery life of the electronic equipment, and thereby improving the user experience.
其中，在本申请实施例中，唤醒阶段也可以称为第一模式，即处理器处于唤醒阶段时，处理器以第一模式工作。In this embodiment of the present application, the wake-up phase may also be called the first mode, that is, when the processor is in the wake-up phase, the processor operates in the first mode.
其中，在本申请实施例中，业务处理阶段也可以称为第二模式，即处理器处于业务处理阶段时，处理 器以第二模式工作。Among them, in the embodiment of the present application, the business processing stage may also be called the second mode, that is, when the processor is in the business processing stage, the processing The device operates in the second mode.
其中，在本申请实施例中，休眠阶段也可以称为第三模式，处理器处于休眠阶段时，处理器以第三模式工作。In this embodiment of the present application, the sleep phase may also be called the third mode. When the processor is in the sleep phase, the processor operates in the third mode.
下面结合图5、图6、图7、图8所示的内容示例性的介绍本申请实施例提供的调整设备功耗的方法的流程。The following exemplarily introduces the process of the method for adjusting device power consumption provided by the embodiment of the present application in conjunction with the content shown in Figures 5, 6, 7, and 8.
下面主要以处理器为CPU为例，示例性的介绍本申请实施例提供的调整设备功耗的方法的流程。处理器也可以是NPU、DSP等。图5为本申请实施例提供的调整设备功耗的方法的流程的一个示例性示意图。The following mainly takes the processor as a CPU as an example to exemplarily introduce the process of the method for adjusting device power consumption provided by the embodiments of the present application. The processor can also be NPU, DSP, etc. FIG. 5 is an exemplary schematic diagram of the flow of a method for adjusting device power consumption provided by an embodiment of the present application.
如图5所示，本申请实施例提供的调整设备功耗的方法的流程包括三个步骤，分别为步骤S501、步骤S502、步骤S503。其中，步骤S503为可选的步骤。As shown in Figure 5, the process of the method for adjusting device power consumption provided by the embodiment of the present application includes three steps, namely step S501, step S502, and step S503. Among them, step S503 is an optional step.
步骤S501：操作***在接收到中断后，配置CPU的频率为第一频率和/或配置CPU的电压为第一电压；并且，指示DMA引擎将数据拷贝到内存中。Step S501: After receiving the interrupt, the operating system configures the frequency of the CPU to be the first frequency and/or configures the voltage of the CPU to be the first voltage; and instructs the DMA engine to copy the data to the memory.
其中，中断(interrupt)也可以称为外部中断或者I/O中断，可以由电子设备上的数据获取装置产生，例如，网卡、键盘、时钟、传感器等，在此不做限定。Among them, an interrupt can also be called an external interrupt or an I/O interrupt, and can be generated by a data acquisition device on an electronic device, such as a network card, keyboard, clock, sensor, etc., which is not limited here.

值得说明的是，在操作***接收到中断后，是否唤醒休眠阶段的CPU取决于CPU处于休眠阶段时能否支持DMA引擎的正常工作。若CPU处于休眠阶段仍然可以为DMA引擎提供时钟等能力，操作***在接收到中断后不会唤醒CPU；若CPU处于休眠阶段不可以为DMA引擎提供时钟等能力，则操作***在接收到中断后唤醒CPU。It is worth noting that after the operating system receives an interrupt, whether to wake up the CPU in the sleep stage depends on whether the CPU can support the normal operation of the DMA engine when it is in the sleep stage. If the CPU is in the sleep phase and can still provide clock and other capabilities to the DMA engine, the operating system will not wake up the CPU after receiving an interrupt; if the CPU is in the sleep phase and cannot provide clock and other capabilities for the DMA engine, the operating system will wake up after receiving the interrupt.

The voltage and frequency of the CPU on the electronic device in the first mode and the second mode may be different.
S502：在数据拷贝完成后，配置CPU的频率为第二频率和/或配置CPU的电压为第二电压；并且，指示CPU对内存中的数据执行处理。S502: After the data copy is completed, configure the frequency of the CPU to the second frequency and/or configure the voltage of the CPU to the second voltage; and instruct the CPU to perform processing on the data in the memory.
其中，配置是由操作***完成的。Among them, the configuration is completed by the operating system.

可选地，第二频率和/或第二电压可以根据当前CPU的负载确定。Optionally, the second frequency and/or the second voltage may be determined according to the current load of the CPU.
