1、设计一个程序实现基于优先数的时间片轮转调度算法调度处理器。

2、假定系统有5个进程，每个进程用一个进程控制块PCB开代表，进程控制块的结构其中：

进程名：作为进程的标识。

指针：进程按顺序排成循环链表，用指针指出下一个进程的进程控制块首地址，最后一个进程中的指针指出第一个进程的进程控制块首地址。

要求运行时间：假设进程需要运行的单位时间数。

已运行时间：假设进程已经运行的单位时间数，初值为0。

状态：可假设有两种状态，就绪状态和结束状态。进程的初始状态都为就绪状态。-1, design a program of priority based on the number of time slice rotation scheduling processor scheduling algorithm.



2, it is assumed that the system 5 processes, each process using a process control block PCB opened on behalf of, the process control block of the structure of which:



Process were: the logo as a process.



Indicators: process cycle according to the order line list, using a process under the guidelines pointed out that the process control block of the first address, the process of the last section of the guide pointed out that the process of a process control block of the first address.



Run-time requirements: if a process needs time to run the unit.



Has running time: the assumption that the process has been running a number of unit time, the initial value is 0.



Status: to assume that two states, state and end state of readiness. Process for the initial state of readiness.
