Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a data processing method and related devices. Background Art

[0002] In terminal devices, embedded multi media cards (eMMC) can be used to store business data. As the business of terminal devices continues to increase, the read and write operations of eMMC become more and more frequent, and the power consumption of eMMC will increase, which in turn leads to the increasing power consumption of terminal devices.

[0003] Therefore, how to reduce the power consumption of eMMC in the terminal device is a technical problem to be solved urgently in this application. Summary of the invention

[0004] The present application provides a data processing method and related devices for solving the problem of high power consumption of eMMC in terminal devices in the prior art.

[0005] In a first aspect, the present application provides a data processing method, which is applied to a terminal device. The method includes: receiving a first instruction, the first instruction is used to instruct the collection and storage of first business data; writing the first business data into a first cache area; if the amount of business data stored in the first cache area is greater than a first data amount threshold, controlling the eMMC to power on, and writing all or part of the business data stored in the first cache area into the eMMC.

[0006] As an example, the terminal device may be an MCU product, such as a sports watch, a bracelet, etc.

[0007] In the method, the first cache area may be deployed in a first storage device of the terminal device, and the first storage device may be a storage device other than the eMMC in the terminal device. As an example, the first storage device may be a memory.

[0008] In this method, the terminal device can control the eMMC to power on through a processor. As an example, the processor of the terminal device can be an MCU.

[0009] In some embodiments, the MCU and the eMMC may be connected via a GPIO bus, which may be used to control the power on and off of the eMMC. As an example, the GPIO bus may include a 3V3 power supply bus.

[0010] In this example, when the amount of business data stored in the first cache area is greater than the first data amount threshold, the MCU can control the 3V3 power supply bus to supply power to the eMMC to control the eMMC to power on.

[0011] In this method, the number of times business data is written into the eMMC can be reduced, thereby reducing the power-on time of the eMMC, which is beneficial to reducing the power consumption of the eMMC in the terminal device.

[0012] In some possible implementations, the first cache area includes multiple sub-cache areas, and the multiple sub-cache areas correspond one-to-one to multiple services. Each sub-cache area in the multiple sub-cache areas is used to store data of the corresponding service, and the amount of service data stored in the first cache area is equal to the sum of the amount of service data stored in each of the multiple sub-cache areas.

[0013] Each of the multiple services has its own corresponding function, and different services have different corresponding functions. As an example, the blood oxygen service can be used to detect the user's blood oxygen, and the heart rate service can be used to detect the user's heart rate.

[0014] In this example, one sub-cache area can store data of one service. That is, each service can have its own corresponding sub-cache area, so that data of different services can be distinguished, which is conducive to improving the accuracy of data storage.

[0015] In some possible implementations, writing all or part of the business data stored in the first cache area into the eMMC includes: writing the business data stored in each of the multiple sub-cache areas into the eMMC.

[0016] As an example, assume that the first cache area includes three sub-cache areas: sub-cache area 1, sub-cache area 2 and sub-cache area 3, wherein sub-cache area 1 can be used to store business data 1, sub-cache area 2 can be used to store business data 2, and sub-cache area 3 can be used to store business data 3.

[0017] When the total amount of the business data stored in the three sub-cache areas exceeds a first data amount threshold, all the business data stored in the three sub-cache areas are written into the eMMC.

[0018] In this implementation, the terminal device can write the business data stored in all sub-cache areas into the eMMC at the same time, and the corresponding control method will be simpler.

[0019] In some possible implementations, the multiple sub-cache areas correspond one-to-one to multiple data volume thresholds.

[0020] Writing all or part of the business data stored in the first cache area into the eMMC includes: writing the business data stored in at least one sub-cache area of ​​the multiple sub-cache areas into the eMMC, and the amount of business data stored in each sub-cache area of ​​the at least one sub-cache area is greater than or equal to a data amount threshold corresponding to each sub-cache area.

[0021] As an example, assume that the first cache area includes three sub-cache areas: sub-cache area 1, sub-cache area 2 and sub-cache area 3, wherein sub-cache area 1 can be used to store business data 1, sub-cache area 2 can be used to store business data 2, and sub-cache area 3 can be used to store business data 3.

[0022] When the total amount of the business data stored in the three sub-cache areas exceeds the first data amount threshold, it is determined whether the amount of the business data stored in each of the three sub-cache areas reaches the corresponding data amount threshold.

[0023] If the data volume of the service data stored in the sub-cache area 1 reaches the data volume threshold corresponding to the cache area 1, the service data 1 stored in the sub-cache area 1 is written into the eMMC.

[0024] In this implementation, the service data stored in the sub-cache area exceeding the corresponding data volume threshold among the multiple sub-cache areas is written into the eMMC, which can improve the resource utilization of each sub-cache area.

[0025] In some possible implementations, the method further includes: after writing all or part of the business data stored in the first cache area into the eMMC, controlling the eMMC to power off.

[0026] In this method, the terminal device can control the eMMC to power off through a processor. As an example, the processor of the terminal device can be an MCU.

[0027] In some embodiments, the MCU and the eMMC may be connected via a GPIO bus, which may be used to control the power on and off of the eMMC. As an example, the GPIO bus may include a 3V3 power supply bus.

[0028] In this example, after all or part of the business data stored in the first cache area is written to the eMMC, the MCU can control the 3V3 power supply bus to stop supplying power to the eMMC to control the eMMC to power off.

[0029] In this method, after the operation of writing business data into the eMMC is completed, the eMMC is controlled to be powered off, thereby saving power consumption of the eMMC.

[0030] In some possible implementations, the method also includes: receiving a second instruction, the second instruction is used to instruct reading second business data; if the business data stored in the first cache area includes the second business data, reading the second business data from the first cache area; if the business data stored in the first cache area does not include the second business data, controlling the eMMC to power on, and reading the second business data from the eMMC.

[0031] In this method, when the first storage area stores the service data to be read, the service data stored in the first cache area can be directly read, which can reduce the number of times the service data is read from the eMMC, thereby reducing the power-on time of the eMMC, and is conducive to reducing the power consumption of the terminal device.

[0034] The receiving module may be used to: receive a first instruction, where the first instruction is used to instruct the collection and storage of first business data.

[0035] The processing module can be used to: write the first business data into the first cache area; if the amount of business data stored in the first cache area is greater than the first data amount threshold, control the eMMC to power on, and write all or part of the business data stored in the first cache area into the eMMC.

[0036] In one possible implementation, the first cache area includes multiple sub-cache areas, and the multiple sub-cache areas correspond one-to-one to multiple services. Each sub-cache area in the multiple sub-cache areas is used to store data of the corresponding service, and the amount of service data stored in the first cache area is equal to the sum of the amount of service data stored in each sub-cache area in the multiple sub-cache areas.

[0037] In a possible implementation, when the processing module writes all or part of the business data stored in the first cache area into the eMMC, it can be specifically used to: write the business data stored in each of the multiple sub-cache areas into the eMMC.

[0038] In a possible implementation, the multiple sub-cache areas correspond one-to-one to multiple data volume thresholds.

[0039] When the processing module writes all or part of the business data stored in the first cache area into the eMMC, it can be specifically used to: write the business data stored in at least one sub-cache area among the multiple sub-cache areas into the eMMC, and the data amount of the business data stored in each sub-cache area of ​​the at least one sub-cache area is greater than or equal to the data amount threshold corresponding to each sub-cache area.

[0040] In a possible implementation, the processing module may also be configured to: after writing all or part of the service data stored in the first cache area into the eMMC, control the eMMC to power off.

[0041] In a possible implementation, the receiving module may also be used to: receive a second instruction, where the second instruction is used to instruct to read second service data.

[0042] The processing module can also be used to: if the business data stored in the first cache area includes the second business data, read the second business data from the first cache area; if the business data stored in the first cache area does not include the second business data, control the eMMC to power on, and read the second business data from the eMMC.

[0097] The application layer may include a series of application packages, and the application layer runs applications by calling the application programming interface (API) provided by the application framework layer.

[0098] For example, the application package may include blood oxygen, heart rate, sleep, step counting, calendar, call, wireless local area network (WLAN), Bluetooth, music, navigation, SMS, map and other applications. Of course, the application layer may also include third-party application packages, such as social applications, third-party music applications, third-party video applications, payment applications, shopping applications, banking applications, chat applications or financial management applications, etc., which are not limited in this application.

[0099] The application framework layer provides an application programming interface (API) and a programming framework for the application programs in the application layer. The application framework layer includes some predefined functions. For example, it may include an activity manager, a window manager, a content provider, a view system, a resource manager, and a display service, etc., and the embodiments of the present application do not impose any restrictions on this.

[0100] The Android runtime consists of a core library, a virtual machine, and a virtual machine monitor. The Android runtime is responsible for scheduling and management of the Android system. The core library consists of two parts: one is the function that the Java language needs to call, and the other is the Android core library. The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0101] The system library can contain modules with multiple functions, such as: surface manager, media library, 3D graphics processing library, and file system.

[0102] The surface manager is used to manage the display subsystem and provides the fusion of two-dimensional and three-dimensional layers for multiple applications. The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files. The media library can support a variety of audio and video encoding formats, such as JPG, PNG, etc. The three-dimensional graphics processing library is used to implement three-dimensional graphics drawing, image rendering, synthesis and layer processing. The file system can be used to manage and store file information, and the recognition algorithm module can be used for sign language recognition, speech recognition and text semantic recognition. Among them, sign language recognition refers to recognizing speech or text as sign language, speech recognition refers to recognizing sign language or text as speech, and text semantic recognition refers to recognizing sign language or speech as text.

[0103] The HAL layer is an encapsulation of the Linux kernel driver, providing an interface to the upper layer and shielding the implementation details of the low-level hardware.

[0104] The HAL layer may include Wi-Fi HAL, audio HAL, and camera HAL.

[0105] The kernel layer is the layer between hardware and software. The kernel layer is used to drive the hardware to make it work. The kernel layer contains at least display driver, camera driver, eMMC driver, sensor driver, etc. Among them, the eMMC driver can be used to drive the eMMC to perform read and write operations.

[0106] The terminal device can write the collected business data into the eMMC, and can read the business data from the eMMC. At present, when there is a need to read and write business data, the data can be read and written through the eMMC. The eMMC can only read and write data when it is powered on.

[0107] The terminal device can control the eMMC to read and write data, as well as control the eMMC power on and off through the processor.

[0108] Figure 4 FIG. 1 is a schematic diagram of the architecture of a terminal device. Figure 4 As shown, it is assumed that the processor of the terminal device includes an MCU, and the MCU and the eMMC can be connected through a bus.

[0109] Optionally, the terminal device may be an MCU product, such as a sports watch, a bracelet, etc.

[0110] In this example, the MCU and the eMMC may be connected via a secure digital input and output (SDIO) bus, and the SDIO bus may be used to control data transmission.

[0111] MCU can control the state of eMMC through SDIO bus. When eMMC needs to read or write data, MCU can control eMMC to switch from sleep state to working state through SDIO bus.

[0112] In addition, the MCU and the eMMC may also be connected via a general purpose input and output (GPIO) bus, which may be used to control the power on and off of the eMMC. As an example, the GPIO bus may include a 3V3 power supply bus.

[0113] For example, when the eMMC needs to read or write data, the MCU can control the eMMC to power on through the GPIO bus. When the eMMC does not need to read or write data, the MCU can control the eMMC to power off through the GPIO bus.

[0114] With the continuous increase in terminal device services, the read and write operations of eMMC are becoming more and more frequent, which may cause the eMMC to be in working state all the time. The power consumption of eMMC is large, which in turn affects the power consumption of the terminal device.

[0115] For example, Figure 5 This is a schematic diagram of an existing eMMC power-on situation. In this example, it is assumed that there are four services: service 1, service 2, service 3, and service 4. The data of these four services are randomly written into the eMMC, which causes the terminal device to always control the eMMC power-on, and the power consumption of the eMMC is large.

[0116] Therefore, how to reduce the power consumption of eMMC in the terminal device is a technical problem to be solved urgently in this application.

[0117] In the technical solution of the present application, the terminal device can first write the collected business data into the first cache area. When the amount of business data stored in the first cache area is greater than the first data amount threshold, the eMMC can be controlled to power on, and all or part of the business data stored in the first cache area can be written into the eMMC.

[0118] As an example, the terminal device may be an MCU product, such as a sports watch, a bracelet, etc.

[0119] In the method, the first cache area may be deployed in a first storage device of the terminal device, and the first storage device may be a storage device other than the eMMC in the terminal device. As an example, the first storage device may be a memory.

[0120] In this method, the number of times business data is written into the eMMC can be reduced, thereby reducing the power-on time of the eMMC, which is beneficial to reducing the power consumption of the eMMC in the terminal device.

[0121] Optionally, the first cache area may include multiple sub-cache areas, and the multiple sub-cache areas may correspond to multiple services one by one, and each of the multiple sub-cache areas may be used to store data of the corresponding service.

[0122] Optionally, after the service data stored in the first cache area is written into the eMMC, the eMMC may be controlled to be powered off.

[0123] Next, this application will combine Figures 6 to 10 , the method of this application is introduced in detail.

[0124] Figure 6 A flow chart of a data processing method provided in this application. Figure 6 As shown, the data processing method may include S601 to S605.

[0125] This method can be applied to Figure 4 In the terminal device shown. As an example, the terminal device may be a wearable device, such as a sports watch, a wristband, etc.

[0126] S601, receiving a first instruction, where the first instruction is used to instruct collection and storage of first business data.

[0127] In the method, the first instruction may be an instruction to start a first service. As an example, the first service may include blood oxygen, heart rate, sleep, step counting, etc.

[0128] The first service data is data of the first service collected by the terminal device based on the first instruction. As an example, assuming that the first service includes blood oxygen, the first service data may include blood oxygen data.

[0129] Optionally, the first instruction may be input by a user. After receiving the first instruction input by the user, the terminal device may collect the first service data, and after collecting the first service data, the terminal device may store the first service data.

[0130] Taking the first service including blood oxygen as an example, assuming Figure 7 A user interface diagram of a terminal device includes a button for starting a blood oxygen service. When a user clicks the button, the terminal device can receive an instruction to start periodic blood oxygen, and collect and store first service data based on the instruction.

[0131] Optionally, the first instruction may also be sent by other terminal devices. As an example, the other terminal device may be a mobile phone.

[0132] For example, taking the first service including blood oxygen as an example, the user can input an instruction to turn on blood oxygen on other terminal devices, and after receiving the instruction to turn on blood oxygen, the other terminal devices send the first instruction to the terminal device. Correspondingly, the terminal device can receive the first instruction.

[0133] S602: Write first service data into a first cache area.

[0134] In the method, the first cache area may be deployed in a first storage device of the terminal device, and the first storage device may be a storage device other than the eMMC in the terminal device. As an example, the first storage device may be a memory.

[0135] S603, determine whether the data volume of the business data stored in the first cache area is greater than the first data volume threshold. If the data volume of the business data stored in the first cache area is greater than the first data volume threshold, execute S604; if the data volume of the business data stored in the first cache area is less than or equal to the first data volume threshold, execute S601.

[0136] Optionally, the first cache area may include multiple sub-cache areas, the multiple sub-cache areas may correspond to multiple services one by one, and each of the multiple sub-cache areas may be used to store data of the corresponding service. The amount of service data stored in the first cache area is equal to the sum of the amount of service data stored in each of the multiple sub-cache areas.

[0137] In this method, the terminal device can determine whether the total amount of service data stored in each sub-cache area is greater than a first data amount threshold, wherein the first data amount threshold can be preset in advance.

[0138] Each of the multiple services has its own corresponding function, and different services have different corresponding functions. As an example, the blood oxygen service can be used to detect the user's blood oxygen, and the heart rate service can be used to detect the user's heart rate.

[0139] In this example, one sub-cache area can store data of one service. That is, each service can have its own corresponding sub-cache area, so that data of different services can be distinguished, which is conducive to improving the accuracy of data storage.

[0140] Optionally, in some embodiments, a sub-cache area may also store data of at least one service, and the functions of the at least one service belong to the same category.

[0141] As an example, the functions of the blood oxygen service and the heart rate service both belong to the health detection function, and the data of the blood oxygen service and the data of the heart rate service can be stored in the same sub-cache area.

[0142] Optionally, the terminal device may periodically determine whether the amount of service data stored in the first cache area is greater than a first data amount threshold. For example, the terminal device may determine once every ten minutes.

[0143] As an example, a timer (or timer) may also be deployed in the terminal device, and the terminal device may use the timer to periodically determine whether the amount of business data stored in the first cache area is greater than a first data amount threshold.

[0144] S604, control the eMMC to power on.

[0145] In this method, the terminal device can control the eMMC to power on through a processor. As an example, the processor of the terminal device can be an MCU.

[0146] In some embodiments, the MCU and the eMMC may be connected via a GPIO bus, which may be used to control the power on and off of the eMMC. As an example, the GPIO bus may include a 3V3 power supply bus.

[0147] In this example, when the amount of business data stored in the first cache area is greater than the first data amount threshold, the MCU can control the 3V3 power supply bus to supply power to the eMMC to control the eMMC to power on.

[0148] Optionally, the terminal device may also control the eMMC to switch from a sleep state to a working state through a processor.

[0149] In some embodiments, the MCU and the eMMC may be connected via an SDIO bus, and the SDIO bus may be used to control the state of the eMMC.

[0150] In this example, when the amount of business data stored in the first cache area is greater than the first data amount threshold, the MCU can control the eMMC to switch from the sleep state to the working state through the SDIO bus.

[0151] Optionally, in some embodiments, the terminal device may also control the power-on of the eMMC based on the number of write times of the business data stored in the first cache area, or control the eMMC to switch from a sleep state to a working state based on the number of write times of the business data stored in the first cache area.

[0152] As an example, if the number of write times of the service data stored in the first cache area reaches a number threshold, the eMMC is controlled to be powered on, wherein the number threshold may be preset in advance.

[0153] S605: Write all or part of the service data stored in the first cache area into the eMMC.

[0154] Optionally, when the terminal device writes all or part of the business data stored in the first cache area into the eMMC, it can first write all or part of the business data stored in the first storage area into the file system, and then write the business data in the file system into the eMMC through the eMMC driver.

[0155] In a possible implementation, writing all or part of the service data stored in the first cache area into the eMMC may include: writing the service data stored in each of the multiple sub-cache areas into the eMMC.

[0156] As an example, assume that the first cache area includes three sub-cache areas: sub-cache area 1, sub-cache area 2 and sub-cache area 3, wherein sub-cache area 1 can be used to store business data 1, sub-cache area 2 can be used to store business data 2, and sub-cache area 3 can be used to store business data 3.

[0157] When the total amount of the business data stored in the three sub-cache areas exceeds a first data amount threshold, all the business data stored in the three sub-cache areas are written into the eMMC.

[0158] In this implementation, the terminal device can write the business data stored in all sub-cache areas into the eMMC at the same time, and the corresponding control method will be simpler.

[0159] In another possible implementation, the plurality of sub-cache areas correspond one-to-one to a plurality of data volume thresholds, which may be preset in advance.

[0160] Accordingly, writing all or part of the business data stored in the first cache area into the eMMC may include: writing the business data stored in at least one sub-cache area among multiple sub-cache areas into the eMMC, wherein the amount of business data stored in each sub-cache area of ​​the at least one sub-cache area is greater than or equal to a data amount threshold corresponding to each sub-cache area.

[0161] As an example, assume that the first cache area includes three sub-cache areas: sub-cache area 1, sub-cache area 2 and sub-cache area 3, wherein sub-cache area 1 can be used to store business data 1, sub-cache area 2 can be used to store business data 2, and sub-cache area 3 can be used to store business data 3.

[0162] When the total amount of the business data stored in the three sub-cache areas exceeds the first data amount threshold, it is determined whether the amount of the business data stored in each of the three sub-cache areas reaches the corresponding data amount threshold.

[0163] If the data volume of the service data stored in the sub-cache area 1 reaches the data volume threshold corresponding to the cache area 1, the service data 1 stored in the sub-cache area 1 is written into the eMMC.

[0164] In this implementation, the service data stored in the sub-cache area exceeding the corresponding data volume threshold among the multiple sub-cache areas is written into the eMMC, which can improve the resource utilization of each sub-cache area.

[0165] In the technical solution of the present application, after all or part of the business data stored in the first cache area is written into the eMMC, the terminal device can also control the eMMC to power off, or control the eMMC to switch from a working state to a sleep state.

[0166] In this method, the terminal device can control the eMMC to power off through a processor. As an example, the processor of the terminal device can be an MCU.

[0167] In some embodiments, the MCU and the eMMC may be connected via a GPIO bus, which may be used to control the power on and off of the eMMC. As an example, the GPIO bus may include a 3V3 power supply bus.

[0168] In this example, after all or part of the business data stored in the first cache area is written to the eMMC, the MCU can control the 3V3 power supply bus to stop supplying power to the eMMC to control the eMMC to power off.

[0169] Optionally, the terminal device may also control the eMMC to switch from a sleep state to a working state through a processor.

[0170] In some embodiments, the MCU and the eMMC may be connected via an SDIO bus, and the SDIO bus may be used to control the state of the eMMC.

[0171] In this example, after all or part of the business data stored in the first cache area is written into the eMMC, the MCU can control the eMMC to switch from a working state to a sleeping state through the SDIO bus.

[0172] In this method, after the operation of writing business data into the eMMC is completed, the eMMC is controlled to be powered off, thereby saving power consumption of the eMMC.

[0173] Figure 8 A schematic diagram of eMMC power-on status is provided for an embodiment of the present application. In this example, it is assumed that there are four services: Service 1, Service 2, Service 3, and Service 4. The data of these four services can be written into the eMMC in certain specific time periods. During this time period, the terminal device can control the eMMC to power on, and during other time periods, the terminal device can control the eMMC to power off, thereby reducing the power consumption of the eMMC.

[0174] Optionally, in some embodiments, after all or part of the service data stored in the first cache area is written into the eMMC, the terminal device may further determine whether there is a need to read the service data in the eMMC. If there is a need to read the service data in the eMMC, the terminal device controls the eMMC to power off after the service data is successfully read.

[0175] In the technical solution of the present application, the terminal device can also receive a second instruction, which is used to instruct the reading of second business data; if the business data stored in the first cache area includes the second business data, the second business data is read from the first cache area; if the business data stored in the first cache area does not include the second business data, the eMMC is controlled to power on, and the second business data is read from the eMMC.

[0176] In some embodiments, the second instruction may be input by a user. For example, the user may input an operation of reading the second service data on the terminal device, and accordingly, the terminal device may receive the second instruction based on the user operation.

[0177] In other embodiments, the second instruction may also be automatically acquired. For example, the time for reading the second service data may be set on the terminal device, and when the time for reading the second service data arrives, the terminal device may automatically acquire the second instruction.

[0178] Optionally, after the terminal device successfully reads the second service data from the eMMC, the terminal device may control the eMMC to power off.

[0179] In this method, the method for the terminal device to control the power on and off of the eMMC can refer to the above-mentioned embodiment and will not be repeated here.

[0180] In this method, when the first storage area stores the service data to be read, the service data stored in the first cache area can be directly read, which can reduce the number of times the service data is read from the eMMC, thereby reducing the power-on time of the eMMC, and is conducive to reducing the power consumption of the terminal device.

[0181] In the present application, the terminal device can control the power on and off of the eMMC through a first bidirectional command and response (command, CMD) signal.

[0182] As an example, the terminal device may send a first CMD signal to the eMMC through a processor, and the first CMD signal may be used to instruct the eMMC to power on or off.

[0183] Optionally, the value of the first CMD signal may include 0 and 1. When the value of the first CMD signal is 1, the first CMD signal may be used to indicate that the eMMC is powered on. When the value of the first CMD signal is 0, the first CMD signal may be used to indicate that the eMMC is powered off.

[0184] For example, in the scenario of writing business data, if the amount of business data stored in the first cache area is greater than the first data amount threshold, the terminal device may send a first CMD signal to the eMMC through the processor, and the value of the first CMD signal may be 1. After all or part of the business data stored in the first cache area is written to the eMMC, the terminal device may send a first CMD signal to the eMMC through the processor, and the value of the first CMD signal may be 0.

[0185] For another example, in the scenario of reading business data, if the amount of business data stored in the first cache area does not include the business data to be read, the terminal device may send a first CMD signal to the eMMC through the processor, and the value of the first CMD signal may be 1. After the business data to be read is successfully read, the terminal device may send a first CMD signal to the eMMC through the processor, and the value of the first CMD signal may be 0.

[0186] In the present application, the terminal device can also control the state of the eMMC through a second CMD signal.

[0187] As an example, the terminal device may send a second CMD signal to the eMMC through the processor, and the second CMD signal may be used to indicate the status of the eMMC.

[0188] Optionally, the value of the second CMD signal may include 0 and 1. When the value of the second CMD signal is 1, the second CMD signal may be used to indicate that the eMMC switches from the sleep state to the working state. When the value of the second CMD signal is 0, the second CMD signal may be used to indicate that the eMMC switches from the working state to the sleep state.

[0189] For example, in the scenario of writing business data, if the amount of business data stored in the first cache area is greater than the first data amount threshold, the terminal device may send a second CMD signal to the eMMC through the processor, and the value of the second CMD signal may be 1. After all or part of the business data stored in the first cache area is written to the eMMC, the terminal device may send a second CMD signal to the eMMC through the processor, and the value of the second CMD signal may be 0.

[0190] For another example, in the scenario of reading business data, if the amount of business data stored in the first cache area does not include the business data to be read, the terminal device may send a second CMD signal to the eMMC through the processor, and the value of the second CMD signal may be 1. After the business data to be read is successfully read, the terminal device may send a second CMD signal to the eMMC through the processor, and the value of the second CMD signal may be 0.

[0191] Optionally, in the present application, the control logic for powering on and off the eMMC and the control logic for switching the eMMC state may be deployed in the eMMC driver.
