Technical Field
The invention relates to the technical field of solid state disks, in particular to a low-power-consumption mode awakening recovery method and device of a solid state disk, computer equipment and a storage medium.
Background
With the rapid development of a Solid State Drive (SSD), performance and power consumption become important standards for measuring the SSD, and a high performance will inevitably lead to a rise in power consumption; therefore, a low power consumption mode of the SSD is important.

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a block diagram of a workflow of wake-up recovery in a low power consumption mode of a solid state disk in the conventional technology. The current wake-up recovery mechanism does not consider unstable factors caused by frequent entering of a low-power-consumption mode, and does not analyze a command issued by a host end to dynamically configure working modes of a CPU and hardware peripherals, so that a lot of idle work or redundant actions are performed to a great extent, the performance and power consumption of a solid state disk are influenced, and the wake-up recovery time of the low-power-consumption mode is prolonged.
Based on the above, the invention optimizes the low power consumption mode awakening recovery process of the traditional solid state disk, dynamically adjusts the working modes of the CPU and the hardware module according to the nature of the command issued by the host, reduces the read-write operation of the storage particles, reduces the overall power consumption of the solid state disk, and accelerates the processing of the non-data transmission command so as to improve the command processing efficiency.

step 204, judging whether the command issued by the host needs to perform data transmission, if not, directly executing the command issued by the host and replying a completion state to the host;
step 206, if necessary, waking up other cores to enable the cores to enter a normal working state, and simultaneously restoring the state and the working parameters before entering the low power consumption mode;
208, detecting the type of the command and the hardware module to be completed, waking up the hardware module to be completed and configuring hardware working information;
