System and method for managing compression and decompression and decompression of system memory in a computer system

a computer system and system memory technology, applied in the field of memory systems, can solve the problems of reducing the cost per storage bit, not being able to achieve significant improvement in the effective operation of the memory subsystem or the software which manages the memory subsystem, and the software solution typically using too many cpu compute cycles and/or adding too much bus traffic, so as to reduce data bandwidth and storage requirements, and ensure the use of the entire system memory space. , the effect of reducing the average compression ratio

AI Technical Summary

Benefits of technology

The technical effect of this patented technology relates to improving computer performance when accessing large amounts of main memory efficiently while maintaining safety measures against overrunouts caused by excessive usage of RAM. It involves optimizing certain components within each component called Core Driver which helps with efficient processing tasks such as performing specific functions like word processors on behalf of CPU cores. This results in improved overall efficiency and reduced costs associated therewith.

Problems solved by technology

Technological Problem: Existing Computational Hardware Systems (CMS), particularly those designed specifically for storing large amounts of RAM, cannot efficiently handle processing requests due to their latency requirements. Additionally, existing methods like dynamic random access memory (RAM) management can only allocate and manage idle areas instead of fully utilizing them.

Abstract

A method and system for allowing a processor or I/O master to address more system memory than physically exists are described. A Compressed Memory Management Unit (CMMU) may keep least recently used pages compressed, and most recently and/or frequently used pages uncompressed in physical memory. The CMMU translates system addresses into physical addresses, and may manage the compression and/or decompression of data at the physical addresses as required. The CMMU may provide data to be compressed or decompressed to a compression/decompression engine. In some embodiments, the data to be compressed or decompressed may be provided to a plurality of compression/decompression engines that may be configured to operate in parallel. The CMMU may pass the resulting physical address to the system memory controller to access the physical memory. A CMMU may be integrated in a processor, a system memory controller or elsewhere within the system.
