设计一个请求页式存储管理方案。并编写模拟程序实现。

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。为简单起见，页面淘汰算法采用FIFO页面淘汰算法，并且在淘汰一页时，只将该页在页表中抹去。而不再判断它是否被改写过，也不将它写回到辅存。

-Page request to design a storage management program. And the preparation 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. For simplicity, the page-out algorithm uses FIFO page-out algorithm, and in one out of only the page in the page table to erase. Rather than to judge whether it had been rewritten, not to write it back to Des depositors.
