AI Technical Summary

Technical Problem

Existing technologies have low flexibility in memory mapping, mainly operating on the local server side, and cannot effectively support multiple memory access methods.

Method used

It employs a programmable storage device that communicates with the host, parses messages sent by the host through a custom transmission protocol, and supports operations such as single address read/write, multiple non-contiguous address read/write, and contiguous address read/write. Combined with address translation and window sliding functions, it dynamically adjusts the memory access method.

Benefits of technology

It implements flexible memory access methods, improves the flexibility and performance of memory mapping, supports multiple operation types, and enhances operational efficiency.

Abstract

This application discloses a memory mapping method, system, device, and storage medium, applied in the field of storage technology. The method includes: receiving a message sent by a host and parsing the message according to a preset custom transmission protocol to obtain a parsing result; determining the host's current operation object, operation type, and operation content based on the parsing result; when the operation object is a register module, performing register operations based on the operation type and operation content; when the operation object is a storage module, performing memory operations based on the operation type and operation content; wherein, the operation types include: single address read, single address write, multiple non-contiguous address read, multiple non-contiguous address write, contiguous address read, and contiguous address write. Applying the scheme of this application can effectively realize memory mapping, provides flexible memory access methods, and offers higher performance.
