Embodiment 1
[0047] Such as image 3 It is an implementation flowchart of Embodiment 1 of the present invention, including the following steps:
[0048] Step 301: press and hold a specific hotkey of the multi-core mobile terminal, the multi-core mobile terminal enters the Download mode, and waits for the PC side to send a handshake signal.
[0049] Specifically, after the multi-core mobile terminal enters the Dwnload mode, it will start the multi-core operating environment. Such as Figure 4As shown, first set the main CPU core to super-protected mode (SVC32 mode), initialize the memory, stack, cache (Cache) and memory management unit (MMU, Memory Management Unit) of the main CPU core, and enable access to the coprocessor, Start the slave CPU core and send a wake-up signal to the slave CPU core. After the slave CPU core in the WIFI state receives the wake-up signal from the master CPU core, it wakes up and waits for the synchronization signal from the master CPU core. After that, the m...

The invention provides a method, system and device for upgrading a multi-core mobile terminal. The method includes the steps that the memory of the multi-core mobile terminal is set to be a memory cache pool, and the size of each buffer region in the memory cache pool is set to the maximum value of blocks in a storage unit of the multi-core mobile terminal; a master CPU core of the multi-core mobile terminal sequentially receives one or more upgrading data packets, wherein the data amount of each upgrading data packet is smaller than or equal to the maximum value of the blocks in the storage unit; the master CPU core extracts one buffer region in the idle state from the memory cache pool when receiving an upgrading data packet each time, the upgrading data packets are stored in the buffer regions, and the buffer regions are placed in an internal queue; a slave CPU core of the multi-core mobile terminal extracts the buffer regions from the internal queue, the upgrading data packets in the buffer regions are written in the storage unit, and the buffer regions are recovered into the buffer regions, in the idle state, in the memory cache pool. By means of the method, the system and the device, the processing speed can be increased, and upgrading efficiency can be improved.
Description
technical field [0001] The present invention relates to the technical field of mobile terminal system upgrades, in particular to a method, system and device for realizing multi-core mobile terminal upgrades. Background technique [0002] The existing mobile terminal upgrade method is mainly to upgrade the system through the PC, and connect the mobile terminal to the PC through the USB interface. The main steps are: [0003] 1. When the mobile terminal is turned off, press and hold a specific hotkey to insert the USB cable to enter the download mode; [0004] 2. After the PC detects that there is a mobile terminal device connected, it sends the upgrade data packet to the mobile terminal through the USB interface. After the mobile terminal completes receiving all the upgrade data packets, it burns the received upgrade data packets to each partition. [0005] With the maturity of mobile terminal technology, multi-core mobile terminals are widely used; while multi-core mobile t...
