AI Technical Summary

⚠Technical Problem

In DRAM-less SSDs, the cache space required for the summary pages storing user data is large, making it difficult to improve GC performance.

⚗Method used

The hardware handles the initialization and content update of the summary page, including determining the physical address location, updating the mapping table, and using hardware to calculate the location of the summary page table and write it to the NAND memory in DRAM-less SSDs.

🎯Benefits of technology

This improved the system's write performance and met the requirements for summary pages in DRAM-less SSDs.

Abstract

The present application relates to a hardware acceleration method, device, computer equipment and storage medium for updating a summary page of an SSD, the method comprising: writing LPA0 by a host and allocating a physical address for writing LPA0; determining whether the current physical address is a position for writing raidparity; if not, determining whether the current physical address is a position for writing a summary page; if not, updating a mapping table and transferring information required for updating a summary page to hardware; calculating a position for storing LPA in a summary page table by hardware according to bank / page / offset in the physical address and the information required for updating a summary page, and then updating the current summary page table; and writing user data into NAND according to the updated current summary page table. The present application processes the initialization and content update of a summary page by hardware, which can improve the write performance of a system and better meet the requirements.
