本次程序的题目为：进程管理――支持多个进程并发运行的简单的进程管理模拟系统，对本实验的分析要求是：⑴系统中的同步机构采用信号量上的P、V操作的机制；⑵控制机构包括阻塞和唤醒操作；⑶时间片中断处理程序处理模拟的时间片中断；⑷进程调度程序负责为各进程分配处理机；⑸根据用户的需求来创建n个进程(n为即满足用户需求,又不超出系统可容的最大进程数),各进程互斥地访问使用临界资源 S1、S2；⑹使用动态优先数(如：随阻塞次数的增加而减小优先数，以提高其优先权)；⑺进程结束后应能够撤消；⑻进程间能实现“发送”和“接收”两个消息缓冲通信操作；⑼系统在运行过程中随机打印出各进程的状态变换过程、系统的调度过程及公共变量的变化情况，在一个进程运行完毕，进入完成状态后，可以将该进程撤消，也可以动态的创建另一个新的进程。-the procedures on the topic of : process management-- to support multiple concurrent processes running a simple process management simulation system for the analysis of the experimental requirements are : 1 system of institutions using synchronous signals on the amount of P, V operation of the mechanism; 2 control agencies, including obstruction and awaken operation ; 3-time interrupt handling procedures-time simulation of interruption; 4 process scheduler is responsible for the allocation process processors; together according to the user"s needs to create process n (n that meet user needs, without exceeding the system can accommodate
