进程调度时进程管理的主要内容之一，通过设计，编制，调试一个简单的进程调度模拟系统，对进程调度，进程运行状态变换加深理解和掌握。模拟计算机操作系统的进程调度,建立进程控制块PCB,要包含有关进程的描述信息,控制信息以及资源信息.模拟系统根据PCB感知进程的存在和通过PCB中所包含的各项变量的变化,掌握进程所处的状态以达到控制进程活动的目的.要实现进程的状态及其转换,进程的创建与撤消,进程的阻塞与唤醒.用P,V原语操作实现进程互斥.-process scheduling process management when one of the main contents, design, develop and debug a simple process of scheduling simulation systems, the process of scheduling, process running Transform deepen understanding and mastering. Computer simulation of the process of scheduling the operating system, create a process control block PCB, to include a descr iption of the process of information, control of information and information resources. PCB simulation system based on perception of the existence and the process by which PCB contained in the variable changes and acquire where the process to achieve control system process activities. to achieve the process of the state and its conversion, the process of setting up and removed, and obstruction of the process of awakening. with P, V orig
