关于进程互斥同步的讨论及PV操作编程的实践

Discussion about Process Mutual Exclusion and Synchronization and Practice in PV operation Programming

本文从进程和并发进程的基本概念出发，较为详细地论述了进程之间的互斥和同步关系，此后，根据个人的编程经验，作者描述了三类同步互斥问题，分别给出了用ＰＶ操作解决这三类问题的编程方法，并对ＰＶ操作编程的特点进行了评价。

This article gives a relatively detailed discussion about mutual exclusive and synchronous relationship between processes. Starting from the basic concepts of process andprocess concurrency. Then according to personal programming experience, the author describes three types of questions concerning mutual exclusion and synchronization, presentsthe programming methods respectively using primitives PV and comments briefly aboutPV operation programming.
