Management method of memory pool for terminal

Abstract

The invention discloses a method for managing memory pools of a terminal, which comprises the steps that: the memory pools are first initialized; a plurality of memory pool arrays are established and parameters of each memory pool are respectively configured; after the memory pools are initialized, flow control of the memory pools is completed by configuring the highest water level and lowest water level, judging the number of memory modules that can be extended continuously and presently positioned between the highest water level and the lowest level in the process of applying for and / or reclaiming the spaces in memory spaces and setting signs for forbidding the applying, wherein, the highest water level and the lowest level are two position lines that show the number of the memory modules that can be expanded continuously in the memory pools. By applying the method of the invention, the number of memory pages in the memory pools can be dynamically expanded by a system, and the distribution efficiency of the memory spaces can be enhanced and memory fragments can be reduced in a certain degree; meanwhile, the corresponding state information and flow control signs can be added to assist the control of the flow control.

Description

technical field [0001] The invention relates to a communication system, in particular to a method for managing a memory pool of a terminal. Background technique [0002] In the software design process of the terminal wireless communication protocol stack, in order to improve the real-time performance of the system, strategies such as reducing thread switching, system calls, or reducing the overhead of memory operations can be adopted; the efficiency of memory management is one of the important factors affecting system overhead. In the design process of communication products, it generally has its own independent memory management system. [0003] In addition, in the design of the protocol stack, each protocol layer has a message processing function module and a message sending and receiving function module; the message processing entity is responsible for processing various messages, and each message may be processed by many entities Or retweet to get complete processing. ...

AI Technical Summary

Problems solved by technology

Since the sending and receiving of messages is generally carried out through a certain communication protocol carried on a certain physical device to achieve message sending and receiving, therefore, there may be problems of message congestion and loss caused by excessive traffic.

In addition, considering that certain resources are consumed in the process of message processing, the message processing capability of each message processing entity has a certain limit, and it is impossible to process infinitely many messages within a certain period of time.
