Abstract

The invention discloses a controller low-power-consumption starting method and device, computer equipment and a storage medium. The method comprises the steps that receiving a command sent by a host;judging whether the command enters a low-power-consumption command or exits the low-power-consumption command;if the low-power-consumption command exits, enabling the CPU 0 to operate the starting code; enabling a running pointer of the CPU 0 to jump to a zero address of the low-power-consumption awakening project; restoring a register value of an interface module in the solid state disk controller; taking out a register value from the dynamic random access memory, and re-assigning the value; recovering the memory area data stored in the dynamic random access memory; and resetting other CPUs except the CPU0, and enabling the firmware to run again. By means of the method, original CPU instructions and firmware stacks are stored. In the wake-up process, operations of stack initialization andfirmware reading from the memory are not needed, so that the wake-up time is shortened.

Description

technical field [0001] The invention relates to a solid-state hard disk, and more specifically relates to a low-power startup method, device, computer equipment and storage medium for a solid-state hard disk controller. Background technique [0002] At present, the process of waking up the SSD controller from the low power consumption mode is as follows: figure 1 As shown, before the SSD controller enters the low power mode, it will clear the command, turn off some module power and clocks to reduce power consumption, turn off all CPUs except CPU0, and make the CPU enter the WFI state. When the existing controller wakes up from the low power consumption mode, the controller receives the interrupt signal sent by the host, and CPU0 starts to run again, and first runs Bootrom (startup code), and Bootrom loads the Bootloader (boot loader) to the ATCM (storage program) of CPU0 area), the CPU running pointer jumps to the ATCM zero address, the Bootloader runs, and the Bootloader r...
