Memory system, memory access request processing method and computer system

Abstract

Disclosed in an embodiment of the present invention are a memory system, memory access request processing method and computer system, the memory system comprising: a first memory and a second memory of different types respectively used for storing the operating data of a processor; a memory indicator table for storing the access memory addresses of a data cell block located in the first memory; a buffer scheduler for receiving a memory access request from a memory controller; determining whether the data cell block corresponding to an access memory address is stored in the first memory or in the second memory, and completing the access memory operation of the memory access request in the determined memory; a migration scheduler for updating the access information of the data cell block; and according to the access information of the data cell block, determining whether to migrate the data cell block in the second memory into the first memory, and updating the memory indicator table after migration.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a memory system, a method for processing memory access requests, and a computer system. Background technique [0002] With the rapid development of computer technology, the requirements for the processing speed of the processor and the reading speed of the data storage are getting higher and higher. A multi-core processor refers to the integration of two or more complete computing engines (cores) in one processor. refer to figure 1 A multi-core and multi-memory computer architecture includes a CPU 100 and a storage module 110; wherein, the CPU includes a plurality of processor cores and cache memory; the memory controller is connected to the storage module through an I / O interface. The storage module contains multiple memory modules. [0003] As the scale of data to be processed by the data center (Data Center) continues to increase, in order to store all the data in ...

AI Technical Summary

Problems solved by technology

[0006] In order to optimize performance, the software is also responsible for collecting information about the frequency of page access, which is generally placed in the page table entry to guide the page migration strategy, such as placing frequently accessed pages in DRAM, the software overhead is relatively large
