计算机系统虚拟存储器基本原理

19、深入理解计算机系统笔记，虚拟存储器，基本原理（1）

3、物理和虚拟寻址 计算机系统的主存被组织成一个由M个连续的字节大小的单元组成的数组。每字节都有一个惟一的物理地址（physical address,PA）。第一个字节地址是0，接下来的字节地址为1，.早期的PC使用物理寻址，而且诸如数字信号处理器...

20、深入理解计算机系统笔记，虚拟存储器，基本原理(2)

在虚拟存储器的习惯用法中，块被称为页。在磁盘和存储器之间传送页面的活动收做交换（swapping）或者页面调度（paging）。一直等待，直到最后时刻，也就是当有不命中发生时，才换入页面的这种策略被称为换需页面调度（demand paging）。4）...
