进程是操作系统实质的关键，本次是设计一个允许N个进程并发运行的进程管理模拟系统，包括以下内容：

（1）简单的进程控制

（2）同步及通讯机构

（3）中断机构

（4）进程调度

-process is the key to real operating system. The design is a process of allowing N-operation with the simulation process management systems, including the following : (1) simple process control (2) synchronization and communication sector (3) disruption (4) Process Scheduling
