SSD low-power-consumption mode exception processing method and device, computer equipment and storage medium

Abstract

The invention relates to an SSD low-power-consumption mode exception processing method and device, computer equipment and a storage medium. The method comprises the steps that a low-power-consumptionentering instruction issued by a host is acquired; judging whether the multi-core is in an abnormal state or not; if the abnormal state does not occur, sending a command completion state to the host,and entering a low power consumption mode; if the abnormal state occurs, sending the abnormal state to the core 0; analyzing the abnormal core and the abnormal command according to the abnormal state,carrying out error processing, and repairing an error site; and issuing an uncompleted or abnormal command again, recording abnormal and wrong commands and reasons, and returning to the step of judging whether the multi-core is in an abnormal state or not. According to the method, the firmware system can normally process exceptions and errors in a low-power-consumption mode, so that firmware is more stable and reliable; Meanwhile, a self-defined full-system command in a low-power-consumption mode is designed to obtain error log information, so that the error detection efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of solid-state storage low power consumption exception processing, and more specifically refers to an SSD low power consumption mode exception processing method, device, computer equipment and storage medium. Background technique [0002] At present, SSD (Solid State Drive) is a mainstream storage device and has a wide range of application scenarios. As an important part of the computer, SSD has high requirements on its performance, power consumption, cost and stability; the low power consumption mode of SSD is designed to save the power consumption of solid-state hard drives; therefore, only the core functions are kept in normal operation, and other The functional module performs power-off or clock-off processing, and the entire solid-state hard drive is in an abnormal working state; therefore, abnormal detection in low-power mode is very important; at the same time, when an abnormality or error occ...

As an important part of the computer, SSD has high requirements on its performance, power consumption, cost and stability; the low power consumption mode of SSD is designed to save the power consumption of solid-state hard drives; therefore, only the core functions are kept in normal operation, and other The functional module performs power-off or clock-off processing, and the entire solid-state hard drive is in an abnormal working state; therefore, abnormal detection in low-power mode is very important; at the same time, when an abnormality or error occurs, only the core function is running normally, so the conventional The error detection method cannot obtain error site information in a timely and normal manner and transmit it to the host; therefore, it cannot meet the requirements
