Method and system for memory management by memory block

Abstract

The invention discloses a method and a system for memory management by a memory block. the method includes applying the memory block of 64KB, dividing the memory block into a memory distribution region and a data storage region, dividing the memory distribution region into fixed-size sub blocks connected in a linked-list mode, writing a linked-list head pointer and the number of idle sub blocks into the data storage region, and realizing memory distribution and recovery through linked-list operations. According to the method, the memory block of 64KB is applied, and distribution and recovery of memory units are performed in a linked-list mode, so that fragments possibly caused during memory distribution are reduced and even eliminated; through the linked-list mode, simple structure is realized, complex operations of traversal and inquiry in the prior art are omitted for memory distribution and recovery, memory processing speed is obviously increased, and memory management efficiency is effectively improved.

Description

Technical field [0001] The invention relates to the field of memory information technology management, in particular to a method and system for realizing memory management through a memory block. Background technique [0002] Memory management occupies a very important position in software development and applications, and has a very important impact on software performance. Since the operating system has to consider the underlying hardware management, limited memory, memory fragmentation, multiple software running at the same time, multi-threaded environment, etc., the allocation and recovery operations of memory are very complicated, and the time limit for memory operations becomes software performance.

Problems solved by technology

Since the operating system has to consider the underlying hardware management, limited memory, memory fragmentation, multiple software running at the same time, multi-threaded environment, etc., the memory allocation and recovery operations are very complicated, and the time limit for memory operations becomes software performance. the bottleneck

Some traditional methods for this are to apply for a large memory, and then divide it into sub-blocks for allocation and use, but the traditional method ignores the organizational structure of sub-blocks, and requires a large number of memory block structure queries during allocation and recycling. Allocation and recovery operations, which leads to inefficient memory management

This effect is especially obvious in a multi-threaded environment, which directly leads to low performance of application software.
