Abstract

The invention provides a method, system and device for reducing key command time delay and a storage medium, and the method comprises the steps: responding to a received read-write command, storing the read-write command of a first priority in a first data slot, and storing the read-write command of a second priority in a second data slot; analyzing the read-write command in the first data slot and the second data slot to obtain a logic unit number corresponding to the read-write command, and extracting a corresponding first sub-data slot from the first data slot according to the logic unit number to sort to form a first queue, extracting the corresponding second sub-data slots from the second data slot to sort so as to form a second queue; setting the proportion of sending the first sub-data slot and the second sub-data slot, and setting counters in the first queue and the second queue respectively; and determining an execution sequence of the read-write commands according to the proportion and the values of the counters in the first queue and the second queue, and executing the commands according to the execution sequence. According to the invention, the time delay of key commands is reduced.

Description

technical field [0001] The present invention relates to the field of data transmission, and more particularly, to a method, system, device and storage medium for reducing the delay of key commands. Background technique [0002] For Nand Flash (flash memory), LUN (Logical Unit Number) is the smallest unit that can independently execute commands and report status. A nand particle may contain one or more LUNs, and these LUNs share a set of nand particles. Interface. At present, the traditional method of executing commands on the same LUN is to execute the commands in the order in which the FW (Firmware) issues the commands. In this way, if the key commands are configured after the ordinary commands, the Lantency (latency) of the key commands will be reduced. ) increases, which greatly reduces the user's satisfaction with the product. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the embodiments of the present invention is to provide a method, system, com...
