Virtual internal storage allocating and managing method of subsystem in communication system

Abstract

A method for allocating and managing virtual memory between subsystems in communication system includes such steps as analyzing the requirement to communication system to determine all subsystems, determining the number of tasks for each subsystem, allocating the system memory space to all subsystems according to actual requirement pluse a certain redundancy, and determing the allocating and managing scheme for the memory of each subsystem. It can improve the stability and reliability of whole system.

Description

technical field [0001] The invention relates to memory allocation management, more specifically, to a virtual memory allocation management method among subsystems in a communication system. Background technique [0002] Memory resources are always the focus and difficulty of management in the project development process in communication systems and embedded systems. Memory management mainly involves issues such as memory leaks, memory allocation efficiency and fragmentation, memory out-of-bounds, and memory protection. Among them, memory leaks are mainly related to programmers themselves and programming tools. For example, if void pointers are not managed in C++, memory leaks are prone to occur. The efficiency and fragmentation of memory allocation can be solved by effective memory allocation management algorithms. Generally, software systems have their own memory allocation management algorithms. The problem of memory out of bounds is rarely considered in existing softwar...

AI Technical Summary

Problems solved by technology

The memory allocation system mainly considers speed bottlenecks and fragmentation issues, especially in embedded real-time systems, where programs must run for a long time with limited resources, so it is required to allocate memory without allowing memory exhaustion or a lot of fragmentation , the present invention also considers to solve this problem
