该系统包括有简单的进程控制、同步与通讯机构，其进程调度算法可任意选择。每个进程用一个PCB表示，其内容根据具体情况设置。各进程之间有一定的同步关系（可选）。系统在运行过程中应能显示或打印各进程的状态及有关参数的变化情况，以便观察诸进程的运行过程及系统的管理过程。-The system includes a simple process control, synchronization and communication agencies, the process scheduling algorithm can be arbitrarily chosen. Each process with a PCB that set the content according to specific circumstances. The synchronization between processes have a certain relationship (optional). During operation the system should be able to display or print the status of the process changes and related parameters in order to observe the operation of various processes and systems management processes.
