Embodiment Construction

[0041] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0042] see Figure 1 to Figure 3 , the present embodiment provides a method for fast booting, including the following steps:

[0043] Step S101: when the main processor is turned on, it loads a kernel (kernel) file from the memory and initializes and starts the coprocessor. The initialization here may be initialization information for the coprocessor to read the memory. Step S102 After the coprocessor is started, send a start-up signal to the main processor; Step S103, after receiving the start-up signal, the main processor sends preloaded algorithm information to the coprocessor and starts the kernel. The algorithm information here includes the algorithm model file Location information stored in memory. Step S104 The coprocessor lo...

Abstract

The invention discloses a method and a device for fast boot-up, which comprises the following steps: after the coprocessor is loaded, a loading complete signal is sent to the main processor; After receiving the loading signal, the main processor loads the root file system from the memory and runs the application program. The main processor restarts the coprocessor, and the coprocessor waits for the algorithm to run on the slave memory after the coprocessor restarts; After the restart of the coprocessor is completed, a restart completion signal is sent to the main processor. After receiving therestart signal, the main processor sends the collected algorithm source data to the coprocessor, and the coprocessor calculates the running result according to the algorithm source data from the memory and returns it to the main processor. In the technical proposal, the algorithm model file is loaded by the coprocessor during the time of loading and running the kernel by the main processor, and then the algorithm can be run after the main processor is turned on, thereby solving the problem that the existing algorithm is loaded again after the kernel is finished, and the boot-up time of the algorithm is long.

Description

technical field [0001] The present invention relates to the technical field of quick start-up of electronic equipment, in particular to a method and device for quick start-up. Background technique [0002] If the smart device has the verification function of human biology when it is turned on, it needs to load the relevant algorithm model for verification when it is turned on. Such as the face unlock function, it is necessary to retrieve the algorithm model stored in Flash (non-volatile storage device) and extract feature points for matching. The size of the existing face algorithm model is too large, and it takes a long time for smart devices to read from Flash to memory, which has a certain impact on the user experience of the face unlock function. Contents of the invention [0003] For this reason, it is necessary to provide a method and device for quick start-up, so as to solve the problem of long start-up time of smart devices with human biological verification funct...
