摘要
该文讨论了操作系统中各种情况下基于P、v原语和信号量机制的解决方案,在介绍了信号量机制的基础上引入PV操作.给出了用pv操作实现进程互斥与同步的基本方法。同时提出了分析和解决此类问题的方法和规律。
This paper discusses All kinds of solutions using P & V primitives and semaphore are offered in process synchronization and mutual exclusion ,Based on the fact that the signal mechanism and PV operation can coordinate the process synchronizetion,this paper provided some methods and rules to analyze and solve this kind of problem accurately.
