说明：   ○1 设计进程进程控制块PCB表结构，分别适用于优先数调度算法和循环轮转调度算法。 PCB结构通常包括以下信息：进程名，进程优先数（或轮转时间片），进程所占用的CPU时间，进程的状态，当前队列指针等。根据调度算法的不同，PCB结构的内容可以作适当的增删。 ○2 建立进程就绪队列。对两种不同算法编制入链子程序。 ○3 编制两种进程调度算法：1）优先度调度；2）循环轮转调度。
(○ design process 1 process control block PCB table structure, namely the number applies to the priority scheduling algorithm and the cycle of rotation scheduling algorithm. PCB structure typically includes the following information: process name, process priority number (or the rotation time slice), the process of occupying CPU time, the process of the state, such as the current queue pointer. According to the different scheduling algorithm, PCB content of the structure can be used for appropriate additions and deletions. ○ 2 to establish the process ready queue. Algorithm on two different procedures for the preparation into the chain. ○ 3 the process of the preparation of two scheduling algorithms: 1) priority scheduling 2) Round-Robin scheduling cycle.)
