8.1 Hardware and control structures Two characteristics of paging and segmentation are the keys to this breakthrough:(最重要的是分页和 分段的两个特点) 1. All memory references within a process are logical addresses that are dynamically translated into hysical addresses at run time. This means that a process may be swapped in and out of main memory such that it occupies different regions (it 程中的所有存储器访问都是逻辑地址,这些逻辑地 址在运行时动态地被转换成物理地址。这意味着 个进程可以被换入或换出主存,因此,在执行过程 中的不同时刻,它占据了主存中的不同区域)8.1 Hardware and Control Structures • Two characteristics of paging and segmentation are the keys to this breakthrough: (最重要的是分页和 分段的两个特点) 1.All memory references within a process are logical addresses that are dynamically translated into physical addresses at run time.
