lift-simulator
- it s a lift simulator, use operating system concept call mutex to implenment a lift. I do it prefectly.
page.change
- 功能介绍: l 输入进程P总共有的页面数,l 并输入系统已经在内存中分配的页面数。当所分配的页面数大于进程P的页面数时,l 则不l 需要进行页面调度工作。 l 由进程P的页面数目,l 程序随机生成一些访问内存的页面号,l 为简化程序,l 这些页面号的数目同l 进程P的进程数目一致(这个缺陷也有待改进)。 l 由用户选择FIFO算法还是LRU算法对进程P的页面访问内存分配的页面进行分配,l 并输出具体的页面访问过程。 原理介绍: 请求页式管理中的置换算法:置换算法在内存中没有空
