操作系统中P、V操作实现进程的同步与互斥

To Achieve Process Synchronism and Exclusion in Operating System By P、V Operations

操作系统是计算机科学与技术的专业基础课程,进程的同步与互斥问题是操作系统中的重要内容。如何正确使用P、V操作实现进程的同步与互斥是防止死锁的重要手段,怎样判断进程是同步还是互斥问题,以及如何正确使用P、V操作防止进程死锁,该文通过具体的实例给出一种通用的解决模式。

Operating system is the foundation courses of Computer Science and Technology,Process synchronism and exclusion problem is the important content of the operating system.How to properly use the P、V operation in process synchronism and ex clusion is an important means to prevent deadlocks,How do we judge the process is synchronism or exclusion problem and how to use P,V operation preventing process Deadlock,This paper given in the mode of a universal solution By Specific examples.
