操作系统课程设计设计文档题目一的内容实现UP、DOWN原语产生3个进程：两个进程模拟需要进入临界区的用户进程。当需要进入临界区时，显示：“进程x请求进入临界区…”，同时向管理进程提出申请；申请返回，表示进入了临界区。在临界区中等待一段随机时间，并显示：“进程x正在临界区…”；当时间结束，显示：“进程x退出临界区…”,同时向管理进程提出退出申请；当申请返回，显示：“进程x已退出临界区。”一个进程作为原语的管理进程，接受其他进程的临界区进入请求：如果允许进入，则根据DOWN 原语的操作步骤设置相应变量，然后返回； 如果不允许进入，则进入循环等待，直到允许为止； 退出时模拟UP 操作。 进程间通信可以采用信号、消息传递、管道或网络通信方式。-Operating system design documents subject curriculum design content of the UP, DOWN primitives have three process
