[OS program] PageReplace DL : 0: 我编写的页面置换演示程序。运行程序后，右端的控制面板可以选择页面置换的算法和指令生成引擎，第一个引擎是按照 “50 的指令是顺序执行的，25 是均匀分布在前地址部分，25％是均匀分布在后地址部分”的要求生成指令，第二个引擎是在320条指令只任意生成指令，默认情况下，程序以1秒的间隔执行全部320条指令，如果用户不愿意等待，可以直接设置为0ms显示全部结果。-I prepared demo page replacement. After running the program, the right side of the control panel to choose the page replacement algorithms and commands to generate the engine, the first engine in accordance with the " 50 of orders are the order of implementation, 25 is uniformly distributed in the former address of 25 is uniformly distributed In the latter part of the address " command to generate the request, the second engine is only 320 instructions to generate arbitrary commands, by default, procedures are in place to 1 second intervals all the implementation of Directive 320, if the user do not want to wait, you can directly set to Show All results 0ms.

[OS program] Vir_Mem DL : 0: 2.设计一个虚拟存储区和内存工作区，并使用下述算法计算访问命中率。 1) 最佳置换算法（Optimal） 2) 先进先出法（Fisrt In First Out） 3) 最近最久未使用（Least Recently Used） 4) 最不经常使用法（Least Frequently Used） 5) 最近未使用法（No Used Recently）其中，命中率＝１－页面失效次数／页地址流长度。试对上述算法的性能加以较各：页面个数和命中率间的关系；同样情况下的命中率比较。 -2. To design a virtual memory storage area and work area, and access using the following algorithm to calculate the hit rate. 1) The best replacement algorithm (Optimal) 2) FIFO (Fisrt In First Out) 3) most recently from lack of use (Least Recently Used) 4) the least frequently used method (Least Frequently Used) 5) does not use a recently (No Used Recently) where hit rate = 1- invalid page number/page address stream length. Test the performance of the algorithms to be compared with each: the page number and the relationship between hit rate the same hit rate in case of comparison.
