一、目的要求

　　用高级语言编写和调试一个进程调度程序，以加深对进程的概念及进程调度算法的理解。



二、例题： 设计一个有 N个进程共行的进程调度程序。

　　进程调度算法：采用最高优先数优先的调度算法（即把处理机分配给优先数最高的进程）和先来先服务算法。

　　每个进程有一个进程控制块（ PCB）表示。进程控制块可以包含如下信息：进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。

-First, the purpose of high-level language requires a process of writing and debugging scheduling procedures in order to deepen their understanding of the process of the concept and understanding of the process of scheduling algorithm. Second, Example: Design of a total of N months the process of the process of scheduling procedures. The process of scheduling algorithm: The number of priority of the highest priority scheduling algorithm (that is, the number of processors allocated to the highest priority to the process) and first-come first-serve algorithm. Each process is a process control block (PCB) said. Process control block can contain the following information: the process name, priority number, arrival time, need to run the time, has spent CPU time, the process of state and so on.
