Method and device for improving low-power-consumption exit efficiency of solid state disk, computer equipment and storage medium

Abstract

The invention relates to a method and device for improving low-power-consumption exit efficiency of a solid state disk, computer equipment and a storage medium. The method comprises the following steps: acquiring a low-power-consumption exit command, and restarting a main control chip according to the low-power-consumption exit command; calling a firmware loading program to execute a low-power-consumption exit action, and reloading firmware, wherein the firmware loading program comprises an execution code for executing the low-power-consumption exit action and firmware loading action; and running the reloaded firmware to process the low-power-consumption exit command so as to allow the main control chip exits from the low-power-consumption state. According to the method, code resources aresaved, the area of code data needing to be stored is reduced, and therefore, power consumption is reduced; and meanwhile, the low-power-consumption exit action and the firmware loading action are completed in the firmware loading program, code initialization, loading and other operations are reduced, time is saved, an exit speed is increased, and then use efficiency is improved.

Description

technical field [0001] The present invention relates to the field of solid-state hard disks, and more specifically refers to a method, device, computer equipment and storage medium for improving the low-power exit efficiency of solid-state hard disks. Background technique [0002] The low power consumption function of the solid-state hard disk can reduce the power consumption of the main control chip of the solid-state hard disk and save energy. In the traditional low power consumption process, when the main control chip enters low power consumption, it is necessary to save the low power consumption exit program and the firmware loading program. When the main control chip exits low power consumption, it needs to run the low power exit program first to perform low power exit actions (link exit L1.2, restore NVME / PCIE registers, etc.), and then jump to the firmware loading program, restart Loads all firmware, enables the entire system to boot, and handles the low-power exit c...

AI Technical Summary

Problems solved by technology

In the whole process of low power consumption, it is necessary to run the program multiple times, which wastes the exit time and affects the exit efficiency. At the same time, there are more codes to be saved, the area is larger, and the power consumption is higher.

[0003] like figure 1 As shown in the figure, it is the time axis of the exit process of the traditional SSD low-power state. It needs to run the low-power exit program and the firmware loading program successively, that is, it needs to run the program multiple times. The entire process exit time is too long, which affects user experience
