Description

Method for adjusting power consumption of equipment and electronic equipment

Technical Field

The present disclosure relates to the field of electronic technologies, and in particular, to a method for adjusting power consumption of an apparatus and an electronic apparatus.

Background

With the development of electronic technology, the functions of electronic devices are continuously enhanced, and the electronic devices are more and more frequently participated in the daily life of consumers. The electronic devices represented by the wearable electronic devices are different from those of mobile phones, tablet personal computers and other electronic devices in use habits, product forms and product purposes of consumers, and therefore the wearable electronic devices are required to have stronger cruising ability.

Under the condition that the battery capacity on the electronic equipment is unchanged, the cruising ability of the electronic equipment can be improved by reducing the power consumption of the electronic equipment. One method for reducing the power consumption of the electronic device is to determine which type of core (such as one a77 large core, three a77 middle cores, four a55 small cores of kylin 9000) needs to be called according to various parameters of a task, a load and the like which are currently running, and call the number of cores, so that the power consumption of the electronic device is reduced by reducing the power consumption of a CPU. Wherein the energy consumption curves of different cores are different. For example, in a low-load scenario such as browsing news, the electronic device mainly invokes the middle core and the small core; in high-load scenes such as games, the electronic equipment can call a big core, so that the power consumption of the electronic equipment is reduced under the condition that the user experience is not reduced.

However, this method is mainly dependent on the architecture of the CPU, and does not achieve a good effect on many electronic devices. For example, in the case where the electronic device is an electronic device that mounts a plurality of CPUs having the same or similar energy efficiency, or the electronic device is an embedded type electronic device, the benefit of the method is small.

Disclosure of Invention

The embodiment of the application provides a method for adjusting power consumption of equipment and electronic equipment. The method for adjusting the power consumption of the device can reduce the power consumption of the electronic device by reducing the voltage and/or the frequency of the processor. The method for adjusting the power consumption of the equipment provided by the embodiment of the application comprises the following steps: firstly, after the processor receives an interrupt initiated by the data acquisition device, the processor is not directly configured to be higher in voltage and/or frequency, but is configured to be lower in voltage and/or frequency, and the DMA controller copies data into the memory, so that the operation capability waste of the processor is reduced, and the power consumption of the processor is also reduced; and secondly, after the data is copied to the memory, the processor is configured to be of higher voltage and/or frequency, so that the processor can rapidly process the data without affecting the normal experience of a user.

In a first aspect, the present application provides a method for adjusting power consumption of a device, where the method includes: after the electronic equipment acquires the first data, the electronic equipment copies the first data into the memory, wherein the processor of the electronic equipment works in a first mode after the electronic equipment acquires the first data and before the first data is copied into the memory; after the first data is copied into memory, the electronic device processes the first data by the processor operating in a second mode; when the processor works in a first mode, the working frequency of the processor is a first frequency, and the working voltage of the processor is a first voltage; when the processor works in the second mode, the working frequency of the processor is the second frequency, and the working voltage of the processor is the second voltage; the first frequency is less than the second frequency and/or the first voltage is less than the second voltage.

In the above embodiments, the processor is configured to have a lower frequency and/or voltage than the processor processes the data after the processor receives the interrupt until the data is copied into memory. Because the processor does not process the data before the data is copied into the memory, the frequency and/or voltage of the processor is configured to be lower than the frequency and/or voltage when the processor processes the data after the processor receives the interrupt until the data is copied into the memory, and the power consumption of the processor is reduced by reducing the waste of the computing capacity of the processor, so that the cruising duration of the electronic equipment is improved.

With reference to some embodiments of the first aspect, in some embodiments, before the electronic device obtains the first data, the processor operates in a third mode; when the processor works in a third mode, the working frequency of the processor is a third frequency, and the working voltage of the processor is a third voltage; the third voltage is less than or equal to the first voltage, and/or the third frequency is less than or equal to the first frequency.

In the above embodiment, the processor may be in the sleep mode before the electronic device obtains the data, and then the voltage and/or frequency of the processor may be the same as the sleep mode after the processor receives the interrupt until the data is copied into the memory.

Before the first mode of the processor is configured, the electronic device can judge what mode the processor is in before, and if the processor is in the second mode, the processor is configured to be in the first mode; if the processor is in the third mode and the third mode is different from the first mode, the processor is configured to be in the first mode; if the processor is in the third mode, and the third mode is the same as the first mode, the mode of the processor is not changed.

Detailed Description

The terminology used in the following embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates to the contrary. It should also be understood that the term "and/or" as used in this application refers to and encompasses any or all possible combinations of one or more of the listed items.

The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

The term "User Interface (UI)" in the following embodiments of the present application is a media interface for interaction and information exchange between an application program or an operating system and a user, which enables conversion between an internal form of information and an acceptable form of the user. The user interface is a source code written in a specific computer language such as java, extensible markup language (extensible markup language, XML) and the like, and the interface source code is analyzed and rendered on the electronic equipment to finally be presented as content which can be identified by a user. A commonly used presentation form of the user interface is a graphical user interface (graphic user interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be a visual interface element of text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc., displayed in a display of the electronic device.

Firstly, because the consumer uses the wearable electronic equipment such as a watch, a bracelet and the like in habit, the electronic equipment is always charged every day as the electronic equipment such as a mobile phone, a tablet and the like; second, the battery capacity of wearable electronic devices is generally smaller than electronic devices such as cell phones, tablets, and the like. In order to improve the experience of the user as much as possible, the power consumption of the wearable electronic device should be reduced as much as possible without affecting the experience of the user and the normal operation of the functions of the wearable electronic device.

One possible method for reducing power consumption of an electronic device is: the operating system configures the voltage (operating voltage) and/or frequency (operating frequency) of the CPU according to various parameters such as the task currently running, the load of the CPU, etc., as shown in fig. 1.

The electronic equipment configures the CPU frequency to be different frequencies according to the type of the currently operated service, and further gives consideration to the performance and the power consumption of the electronic equipment. As shown in fig. 1, when the electronic device runs the first type of service, the CPU frequency is the lowest; secondly, when the electronic equipment runs the second type of service, the CPU frequency is low; thirdly, when the electronic equipment runs the third type of service, the CPU frequency is higher; the CPU frequency is highest when the electronic device is running a fourth type of service. Wherein the load of the first type of traffic is lower than the load of the second type of traffic, and the load of the second type of traffic is lower than the load of the third type of traffic; the load of the third type of traffic is lower than the load of the fourth type of traffic.

For an operating system based on a Linux kernel, the voltage and frequency of the CPU may be adjusted based on a CPU freq module in the Linux kernel. Among other things, the cpu freq module provides a wide variety of scheduling policies, such as Performance policies, powersave policies, userspace policies, ondemand policies, and the like. The Userspace strategy allows the operating system to adjust the voltage and frequency of the CPU by itself, thereby implementing the method shown in fig. 1.

However, for electronic devices represented by wearable electronic devices, there are few high-load services that can be run on the electronic devices, and there is also little time for the electronic devices to run the high-load services, and the load gap for most of the services is not large, as shown in fig. 2.

As shown in fig. 2, when the load difference of different types of services on the electronic device is not large, the difference of CPU frequencies corresponding to the different types of services is not large. Secondly, in the daily life of consumers, the electronic equipment is more in a low-load state, namely the running time of high-load business of the electronic equipment is shorter.

In the case shown in fig. 2, the power consumption benefit obtained by the method of configuring the CPU frequency to be different frequencies according to the type of the currently running service is smaller, so that the power consumption cannot be effectively reduced, or the power consumption benefit obtained by the method shown in fig. 1 is still insufficient to meet the requirements of consumers.

Based on the above, the embodiment of the application provides a method for adjusting power consumption of equipment and electronic equipment. The method for adjusting the power consumption of the equipment divides the processing process of the CPU after being interrupted and awakened into at least two stages, namely an awakening stage and a service processing stage, based on the interrupt processing capability of an operating system; in the wake-up stage, the operating system of the electronic equipment configures the frequency and/or voltage of the CPU to be lower, so that the power consumption is reduced; in the service processing stage, an operating system on the electronic equipment can configure the frequency and/or the voltage of the CPU based on the type of the service, or configure the frequency and/or the voltage of the CPU to be higher, so that the experience of a user is ensured.

It should be noted that, the method for adjusting power consumption of the device provided in the embodiments of the present application may be applied to a CPU of an electronic device, or may also be applied to other chips or processing units inside the electronic device, for example, a digital signal processor (digital signal processor, DSP), a neural-network processor (neural-network processing unit, NPU), or the like, which may receive an interrupt and may be configured with different operating voltages and/or operating frequencies. The processor may also include one or more of DSP, CPU, NPU, i.e., the processor is integrated as a chip with one or more of DSP, NPU, CPU.

Hereinafter, a method for adjusting power consumption of a device provided in the embodiment of the present application will be mainly described by taking a CPU as an example.

Wherein, during the wake-up phase, the CPU is hardly operated, and the capability of opening a clock and the like gives the direct memory access (DirectMemorty Access, DMA) engine (or DMA chip, or DMA controller) so that the DMA engine can read the data of the data acquisition device (such as peripheral, sensor, network card) (which may also be referred to as the data acquisition device) into the memory. The memory may include an L1 memory, an L2 memory, an L3 memory, and/or a memory of the electronic device, which are integrated in the CPU.

Optionally, in some embodiments of the present application, during the wake-up phase, the electronic device may make some preparation for the service processing phase, for example, initializing some internal parameters, etc., which are not limited herein.

In the service processing stage, the CPU processes the data in the memory according to the logic of the upper layer service, and the result is obtained through calculation.

It should be noted that, in the wake-up phase, the CPU may not process the data at this time, since the DMA engine has not yet read all the data into the memory.

It can be appreciated that, compared to the method shown in fig. 1, the method for adjusting power consumption of an apparatus provided in the embodiment of the present application, because the problem that the CPU maintains a higher frequency and/or voltage at the empty load is found on a smaller granularity, further reduces the power consumption of the electronic apparatus by reducing the frequency and/or voltage of the CPU under the empty load condition.

The method for adjusting the power consumption of the device according to the embodiment of the present application is first described by taking an electronic device as a watch and a bracelet as an example.

As shown in fig. 3A, the process that the watch receives the first message sent by the network and displays the message on the screen can be divided into four stages.

Stage 1: the screen of the watch may not display any content and is in a rest state. The wristwatch 1 is connected to the internet by near field wireless communication technology such as bluetooth, wiFi, etc., or may be connected to the internet by cellular mobile communication, not limited herein. Alternatively, the watch may display some content, such as time, etc.

Stage 2: the watch receives the message sent from the server in the network. The watch receives data through the network card and stores the data into the network card. Alternatively, in some embodiments of the present application, the watch may receive data via a bluetooth hardware module or a WiFi hardware module.

Stage 3: after the network card of the watch receives the data, sending an interrupt to an operating system, and waking up a CPU; at the same time, the DMA engine copies the data from the network card to memory.

Stage 4: the CPU processes the data copied into the memory; after the CPU finishes processing the data according to the logic of the upper layer service, the electronic equipment lights up the screen and displays the content of the message correspondingly.

As shown in fig. 3B, phase 1 and phase 2 may correspond to sleep phases; stage 3 corresponds to a wake-up stage; stage 4 corresponds to a traffic processing stage.

In the sleep stage, the frequency of the CPU is lowest and is A1Hz; in the wake-up stage, the CPU frequency is A2Hz; in the service processing stage, the frequency of the CPU is highest, and the frequency is A3Hz. Wherein A1 is less than or equal to A2, and A2 is less than A3. The sleep stage may also be referred to as sleep mode or sleep state, and for example, a portion of the CPU may enter the sleep stage via WFI (wait for interrupt) instructions and WFE (wait for event) instructions.

It should be noted that, in the case where A2 is equal to A1, the wake-up phase may be considered as the same as the sleep phase, that is, in the case where the CPU is in the sleep phase, the DMA engine on the electronic device may still work normally; in this case, it can be considered that the method of adjusting the power consumption of the device of the present application is to substantially lengthen the time of the sleep stage of the CPU, which is not awakened by the interrupt sent by the data acquisition means but by the interrupt of the DMA engine for notifying the CPU that the data has been copied.

Alternatively, in some embodiments of the present application, A3 may be a variable, i.e., A3 may be configured to specific different values according to the type of current service. The method for determining A3 may refer to the content shown in fig. 1, and will not be described herein.

It should be noted that the voltage variation trend of the voltage of the CPU at different CPU stages may be similar to that shown in fig. 3B.

Alternatively, in some embodiments of the present application, stage 1 and stage 2 may correspond to other CPU stages, not limited herein. For example, stage 1 and stage 2 may correspond to different CPU stages; as another example, phase 1 and phase 2 may correspond to a traffic processing phase or the like.

As shown in fig. 4A, the process of measuring heart rate by the user using the bracelet can be divided into four phases.

Stage 1: the screen of the bracelet can not display any content and is in a screen-off state. Alternatively, the screen of the wristband may also display certain content through an off-screen display (AOD) technique.

Stage 2: in response to receiving a user operation, the electronic device begins to perform heart rate detection; alternatively, the electronic device performs heart rate detection periodically. In the process of executing heart rate detection, the electronic device records the intensity change of the light reflected by the wrist through the photoelectric sensor.

Optionally, in some embodiments of the present application, the electronic device may also perform heart rate detection in other ways through other hardware modules.

Stage 3: after heart rate detection is completed, or in the heart rate detection process, the wristband copies data from the photoelectric sensor to the memory through the DMA engine.

Stage 4: the CPU calculates the heart rate based on the recorded changes in the intensity of the light or other parameters, based on photoplethysmography or other methods, algorithms, and displays the heart rate data on the display screen of the wristband. As shown in fig. 4A, the electronic device displays the heart rate 90 on the display screen of the wristband.

As shown in fig. 4B, phase 1 may correspond to a sleep phase; phase 2 and phase 3 correspond to the wake-up phase; stage 4 corresponds to a traffic processing stage.

In the sleep stage, the frequency of the CPU is lowest and is B1Hz; in the wake-up stage, the CPU frequency is B2Hz; in the service processing stage, the frequency of the CPU is highest, and the frequency is A3Hz. Wherein B1 is less than or equal to B2, and B2 is less than B3.

Alternatively, stage 2 may correspond to other CPU stages in some embodiments of the present application, without limitation. For example, phase 2 may correspond to a traffic processing phase or the like.

Referring to fig. 3A, fig. 3B, fig. 4A, and fig. 4B, it may be derived that, first, the method for adjusting power consumption of a device provided in the embodiment of the present application divides a CPU phase into at least two phases, where at least two phases include a wake-up phase; secondly, by reducing the frequency or voltage of the CPU in the wake-up stage, the method for adjusting the power consumption of the device reduces the power consumption of the electronic device.

It should be noted that the methods shown in fig. 1 and 2 can be equally applied to the frequency adjustment of the CPU in stage 4 in fig. 3A, 3B, 4A and 4B. That is, the method for reducing power consumption of the electronic device provided by the embodiment of the application further reduces power consumption of the electronic device, prolongs the endurance time of the electronic device, and further improves the experience of a user on the basis of the methods shown in fig. 1 and 2.

In this embodiment, the wake-up phase may also be referred to as a first mode, that is, when the processor is in the wake-up phase, the processor operates in the first mode.

In this embodiment, the service processing stage may also be referred to as a second mode, that is, when the processor is in the service processing stage, the processor operates in the second mode.

Alternatively, in some embodiments of the present application, the operating system may not wake up the CPU after receiving the interrupt if the CPU is in a sleep stage at this time.

It should be noted that, after the operating system receives the 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 the CPU is in the sleep stage. If the CPU is in the sleep stage, the CPU can still provide the capabilities of a clock and the like for the DMA engine, and the operating system cannot wake up the CPU after receiving the interrupt; if the CPU is in the sleep stage and can not provide the capabilities of clocks and the like for the DMA engine, the operating system wakes up the CPU after receiving the interrupt.

Alternatively, the second frequency and/or the second voltage may be determined according to the load of the current CPU.

After the data copying is completed, the CPU starts to execute processing on the data in the memory according to the logic of the service.

In the scenario shown in fig. 3A and fig. 3B, the data is a message copied from the network card into the memory, and the CPU performs a process of displaying the message on the screen; in the above scenario shown in fig. 4A and 4B, the data is the light intensity value copied from the photosensor into the memory, the CPU performs processing to calculate the heart rate from the light intensity value, and the calculated heart rate is displayed on the screen.

Optionally, in some embodiments of the present application, after the operating system receives the interrupt, the operating system records the frequency and/or voltage of the current CPU before configuring the frequency of the CPU to the first frequency and/or configuring the voltage of the CPU to the first voltage.

Alternatively, in some embodiments of the present application, the CPU may transition to the sleep stage after processing the interrupt-induced traffic, i.e., after processing the memory data.

As shown in fig. 9A, when the CPU is in the sleep stage, the CPU frequency is C1; after receiving the data reported by the sensor, the CPU stage is changed into a wake-up stage, and the CPU frequency is C2 in the wake-up stage; after a period of time, the CPU phase becomes the traffic processing phase, with CPU frequency C3. Wherein C1 is less than or equal to C2, and C2 is less than C3.
