支持多个进程并发运行的简单进程管理模拟系统。本系统的同步机构采用的信号量上的P，V操作的机制；控制机构包括阻塞和唤醒操作；时间片中断处理程序模拟的时间片中断；进程调度程序负责为各进程分配处理机。-support multiple concurrent processes running a simple process management simulation system. The system adopted by the synchronization signal quantity of P, V operation of the mechanism; Control agencies, including obstruction and awaken operation; Time Slice interrupt handling procedures-time simulation of interruption; the process scheduler is responsible for the allocation process processor.
