Description: 设计一个请求页式存储管理方案。并编写模拟程序实现之。产生一个需要访问的指令地址流。它是一系列需要访问的指令的地址。为不失一般性，你可以适当地（用人工指定地方法或用随机数产生器）生成这个序列，使得 50 ％的指令是顺序执行的。 25 ％的指令均匀地散布在前地址部分， 25 ％的地址是均匀地散布在后地址部分。页面替换算法采用 Fifo 页面替换算法，在发生页替换时，不仅需要更改页表，还需将被替换的页回到辅存。-Page request to design a storage management program. And to prepare the realization of simulation program. A need to access the instruction address stream. It is a series of instructions need to access the address. For losing the general, you can use an appropriate (designated land use of artificial methods or random number generator) to generate this sequence, making 50 of orders are the order of execution. 25 of the command to spread evenly in the former address of 25 percent of the addresses are evenly spread in the latter part of the address. Page replacement algorithm using Fifo page replacement algorithm, page replacement in the event of not only need to change the page tables, will be needed to replace the page to return to Des depositors.
