在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。当就绪状态进程个数大于处理器数时，就必须依照某种策略来决定哪些进程优先占用处理器。本实验模拟在单处理器情况下处理器调度。要求设计一个按优先数调度算法和一个按时间片轮转法实现处理器调度的程序，选择其中一个调度算法,实现处理器调度。-The introduction of multi-channel programming system, often there are a number of processes at the same time in a state of readiness. When the state of the process in place is greater than the number of processors a few hours, it is necessary to some kind of strategy in accordance with the process to determine which priority occupied processor. Experimental simulation of the processor in a single processor scheduling circumstances. Asked to design a priority scheduling algorithm and a few time-chip processor rotation method, the activation procedures, select one of scheduling algorithm, the realization of processor scheduling.
