模拟进程调度程序。进程调度是处理机管理的核心内容。本实验要求用C++语言编写和调试一个简单的进程调度程序。通过本实验可以加深理解有关进程控制块、进程队列的概念，并体会和了解时间片轮转调度算法的具体实施办法。-Simulation process scheduler. Process scheduling process management is the core content. The experiment with C++ language writing and debugging a simple process scheduler. Through this experiment can deepen our understanding of the process control block, the concept of the process of formation, and experience and understanding round-robin scheduling algorithm specific measures for implementation.
