Document Type and Number:
WIPO Patent Application WO/2020/169065
Kind Code:
A1
Abstract:
Disclosed are a pre-reading method and apparatus based on a memory limited SSD, and a computer device and a storage medium. The method comprises: acquiring a read command request submitted by a host, the read command request comprising a read command submitted by the host (S202); determining whether the host is in a sequential read mode according to read command information in the read command request (S204); if the host is in the sequential read mode, notifying a pre-reading module to insert a pre-reading command when the host has no command input (S206); pre-loading data into a NAND cache register according to the pre-reading command (S208); and directly initiating a data transmission operation when a subsequent command of the host is issued and hits the data (S210). In the method, a host sequential read sequence is predicted by identifying a sequential read request, the initiation of a NAND read command is triggered when a host command is not issued in a timely manner, and data is loaded into a NAND cache register, so that data transmission is directly carried out when a subsequent read command comes, and read performance bandwidth is guaranteed.
