[0029] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0030] In order to solve the above problems, the first aspect of the present invention provides a Bluetooth service startup method for a multi-core processor of an electronic device. This method can be used to simultaneously start the Linux system and the Bluetooth service through multiple cores of the multi-core processor, greatly shortening the startup time of the Bluetooth service, so that users can quickly use the Bluetooth service and improve the user experience.

[0031] In an embodiment, a multi-core processor is a very large-scale integrated circuit, and is the computing and control core of a computer. Current processors are all multi-core processors. For example, a multi-core processor may be a quad-core processor, etc., and there is no limitation to this. It should be noted that each core of a multi-core processor can run independently and process different tasks in parallel.

[0032] Reference below Figure 1 Describe the Bluetooth service startup method according to an embodiment of the present invention, such as Figure 1 As shown, the method at least includes: step S1 to step S2.

[0033] Step S1, in response to a Linux system startup instruction, controlling the Linux system startup through a first core.

[0034] Specifically, the electronic device is configured with a Linux system and a FreeRTOS system. When the electronic device is powered on and receives a Linux system startup instruction, the first core controls the Linux system startup. Among them, the FreeRTOS system is a lightweight real-time operating system, and its functions include: task management, time management, semaphore, message queue, memory management and recording functions, etc., which can basically meet the needs of smaller systems, and the processing efficiency is higher and faster than that of the Linux system. The electronic device can provide Bluetooth functions for audio or home appliances.

[0035] Step S2, during the booting process of the Linux system, the Bluetooth service of the FreeRTOS system is started through the second core, and the Linux system is controlled to continue booting through the first core.

[0036] Specifically, during the startup process of the existing Linux system, it is necessary to first load the boot loader and the Linux system kernel, and then start the Bluetooth system of the Linux system, that is, loading the boot loader, the Linux system kernel and starting the Bluetooth system of the Linux system are performed serially. In other words, the Bluetooth protocol stack and Bluetooth service of the Linux system cannot be started before the loading of the boot loader and the Linux system kernel is completed. Loading the boot loader and the Linux system kernel will consume a certain amount of time, thereby greatly extending the startup time of the Bluetooth service, causing inconvenience to users in using Bluetooth and reducing the user experience. In order to solve the above problems, the electronic device in the present application is configured with a Linux system and a FreeRTOS system, and the FreeRTOS system has a Bluetooth system, and the FreeRTOS system has the characteristics of simplicity and high processing efficiency. Therefore, during the startup of the Linux system, the principle that each core of the multi-core processor can run independently is utilized, and the Bluetooth service of the FreeRTOS system and the Linux system are started respectively by multiple cores of the multi-core processor of the electronic device. That is, while the first core of the multi-core processor continues to start the Linux system, that is, while the first core is loading the boot loader and the Linux system kernel, the second core of the multi-core processor starts the Bluetooth service of the FreeRTOS system, wherein the Bluetooth service can be Bluetooth connection and Bluetooth playback, etc., and the Bluetooth service of the FreeRTOS system can be started quickly, so there is no need to wait for the boot loader and the Linux system kernel to be loaded before starting the Bluetooth service, but the Bluetooth service is started at the same time as the boot loader and the Linux system kernel, which greatly shortens the startup time of the Bluetooth service, so that users can quickly use the Bluetooth service and improve the user experience.

[0037] According to the Bluetooth service startup method of the embodiment of the present invention, based on the electronic device being configured with a Linux system and a FreeRTOS system, and utilizing each core of the multi-core processor of the electronic device to process tasks in parallel, during the Linux system startup process, the Bluetooth service of the FreeRTOS system is started and the Linux system is continued to be started through multiple cores of the multi-core processor of the electronic device, that is, the multi-core processor simultaneously starts the Bluetooth service of the FreeRTOS system and continues to start the Linux system, thereby eliminating the need to wait for the boot loader and the Linux system kernel to be loaded before starting the Bluetooth service, greatly shortening the startup time of the Bluetooth service, so that users can quickly use the Bluetooth service and improve user experience.

[0038] In some embodiments, the electronic device also includes a static random access memory (SRAM). During the Linux system startup process, the Bluetooth service of the FreeRTOS system is started through the second core, and the Linux system is controlled to continue to start through the first core, including: after loading the romcode of the Linux system and loading bl2, controlling the second core to start, starting the Bluetooth service of the FreeRTOS system from the static random access memory through the second core, and controlling the Linux system to continue to start through the first core.

[0039] Specifically, during the boot process of the Linux system, after the first core loads the romcode of the Linux system and loads the bootloader bl2, that is, after the electronic device is powered on, the romcode of the Linux system is first loaded, wherein the romcode is loaded to initialize the processor of the electronic device, and then the first core loads bl2, after loading the romcode of the Linux system and loading bl2, the code of the freertos system is read from the flash memory in bl2, and then the freertos system is loaded into the static random access memory, and the second core is started in bl2, and the second core starts the Bluetooth service of the freertos system from the static random access memory, thereby ensuring that the Bluetooth service of the freertos system can be quickly started, and the Linux system is controlled to continue to start through the first core. In addition, the static random access memory can store data as long as it is powered on. Among them, bootloader bl2 is the second stage of the bootloader, and the main functions of bl2 are to initialize the hardware devices used in this stage, detect the system memory mapping, read the kernel from Flash into RAM, set startup parameters for the kernel, and call the kernel, etc.

[0040] In some embodiments, starting the Bluetooth service of the freertos system from the static random access memory through the second core includes: loading the freertos system from the static random access memory through the second core, initializing the Bluetooth driver of the freertos system through the freertos system, initializing the Bluetooth protocol stack of the freertos system, and initializing the Bluetooth service of the freertos system.

[0041] Specifically, before the freertos system starts the Bluetooth service, the freertos system initializes the Bluetooth driver, Bluetooth protocol stack, A2DP (Advanced Audio Distribution Profile, Bluetooth audio transmission model agreement) / AVRCP (Audio / VideoRemote Control Profile, audio and video remote control protocol) of the freertos system, that is, the Bluetooth audio transmission protocol and the Bluetooth service, so as to ensure that the Bluetooth service of the freertos system can be used. After the Bluetooth driver, Bluetooth protocol stack, A2DP / AVRCP Bluetooth audio transmission protocol and Bluetooth service are initialized, the second core starts the Bluetooth service of the freertos system from the static random access memory, thereby realizing the startup of the Bluetooth service of the freertos system, so that users can quickly use the Bluetooth service and improve the user experience. In addition, the Bluetooth driver is used for electronic devices to connect to the driver software of other devices, and the Bluetooth protocol stack is an open specification for wireless data and digital communication. The freertos system is also used to load the Bluetooth protocol stack.

[0042] In some embodiments, before the freertos system initializes the Bluetooth service of the freertos system, the audio driver is initialized by the freertos system to ensure that the Bluetooth service can be used. The audio driver is used to transmit audio data.

[0043] In some embodiments, the Bluetooth service startup method further includes: determining whether the Linux system has been started and whether the Bluetooth service of the freertos system is used; if the Linux system has been started or the Bluetooth service of the freertos system is not used, then controlling the freertos system to exit to release the use of the second core. Specifically, determining whether the Linux system has been started and whether the Bluetooth service of the freertos system is used, that is, after the Linux system has been started, its Bluetooth service can be used, and there is no need to use the Bluetooth service of the freertos system at this time. Therefore, if the Linux system has been started, the electronic device can use the Bluetooth service of the Linux system at this time, or the Bluetooth service of the freertos system is not used, that is, the user does not use other devices to connect the Bluetooth service of the electronic device, then controlling the freertos system to exit to release the use of the second core, so as to provide the memory of the multi-core processor to the Linux system, and if the Linux system has not been started, then continuing to use the Bluetooth service of the freertos system, that is, controlling the freertos system to continue normal operation.

[0044] In addition, the Bluetooth service of the freertos system can also be used after the Linux system is started. The Bluetooth service of the Linux system can interact with other modules of the electronic device.

[0045] In some embodiments, the Linux system is controlled to continue to start through the first core, that is, after loading the romcode of the Linux system and loading bl2, the Linux system is initialized, that is, the double data rate synchronous dynamic random access memory (Double Data Rate, DDR), loading BL31 / BL32, loading the boot loader, loading the Linux system kernel (kernel), and starting the Bluetooth service of the Linux system. In other words, the Bluetooth service of the Linux system can be started after the Linux system loads the Linux system kernel, and it should be noted that before starting the Bluetooth service, the Bluetooth driver, Bluetooth protocol stack, A2DP / AVRCP Bluetooth audio transmission protocol and Bluetooth service need to be initialized. Among them, BL31 is a system security monitor, and the main functions of BL31 are as a startup process, initializing hardware and loading BL32; loading BL32 includes setting the stack pointer and initializing hardware, such as initializing the memory pipeline unit, global variables, interrupt controller and timer; the boot loader is used to detect the external memory and load the programs needed in the subsequent process and set the network and memory.

[0046] It should be noted that before the Linux system kernel is loaded through the first core, only the first core is started by default. The first core loads the romcode of the Linux system and loads bl2, and starts the second core in bl2.

[0047] In some embodiments, after the Bluetooth service of the Linux system is started and the freertos system releases the use of the second core, that is, after the Linux system is started, its Bluetooth service can be used, and there is no need to use the Bluetooth service of the freertos system. Then the Bluetooth service of the Linux system is controlled to start, and the Linux system obtains the Bluetooth service control authority so that the electronic device can use the Bluetooth service of the Linux system.

[0048] Reference below Figure 2 The figure illustrates an example of starting the Bluetooth service in an embodiment of the present invention, and the specific contents are as follows.

[0049] Step S3: the first core of the multi-core processor of the electronic device starts the Linux system.

[0050] Step S4: the first core of the multi-core processor loads the romcode of the Linux system.

[0051] Step S5: The first core of the multi-core processor loads bl2 of the Linux system, and executes steps S6 and S13.

[0052] Step S6: the second core of the multi-core processor starts the Bluetooth service of the FreeRTOS system from the static random access memory.

[0053] Step S7, the freertos system initializes the Bluetooth audio driver.

[0054] Step S8, the freertos system initializes the Bluetooth driver.

[0055] Step S9: the freertos system initializes the Bluetooth service.

[0056] Step S10, the second core of the multi-core processor starts the Bluetooth service of the FreeRTOS system, that is, while the first core of the multi-core processor starts the Linux system, the second core starts the Bluetooth service of the FreeRTOS system.

[0057] Step S11, determine whether the Linux system is started and whether the Bluetooth service of the FreeRTOS system is used. If so, execute step S12, otherwise execute step S11.

[0058] Step S12, control the freertos system to exit, and execute step S17.

[0059] Step S13, the first core of the multi-core processor controls the Linux system to initialize the double rate synchronous dynamic random access memory.

[0060] Step S14: the first core of the multi-core processor loads BL31 / BL32.

[0061] Step S15: the first core of the multi-core processor loads a boot loader (Universal Boot Loader, U-boot).

[0062] Step S16: The first core of the multi-core processor loads the Linux system kernel, and initializes the Bluetooth driver and the Bluetooth audio driver.

[0063] Step S17, canceling Bluetooth control.

[0064] Step S18: The electronic device provides Bluetooth service.

[0065] Therefore, during the Linux system startup process, the Bluetooth service of the FreeRTOS system and the Linux system are started respectively by multiple cores of the multi-core processor of the electronic device, that is, the multi-core processor starts the Bluetooth service of the FreeRTOS system and continues to start the Linux system at the same time, so there is no need to wait for the boot loader and the Linux system kernel to be loaded before starting the Bluetooth service, which greatly shortens the startup time of the Bluetooth service, so that users can quickly use the Bluetooth service and improve the user experience.
