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-Generate a need to access the instruction address stream. It is a series of instructions need to access the address. Is without loss of generality, you can properly (using manual methods or the designated land use random number generator) to generate this sequence. For simplicity, the page-out algorithm uses FIFO page-out algorithm, and eliminated one, only to be wiped off the page in the page table. Rather than to determine whether it had been rewritten, not to write it back to secondary memory
