线性地址和物理地址 [英] Linear address and physical address

问题描述

什么是线性地址?它与物理地址有何不同?

What is linear address? How is it different from physical address?

推荐答案

Linear address is generated after before page表映射.物理地址是生成before after页表映射(即分页).

Linear address is generated after before page table mapping. Physical addres is generated before after page table mapping(ie paging).

线性地址，通过添加创建基址的逻辑地址段、CS、DS、ES、SS、FS 或 GS​​.

Linear Adress,created by adding logical address to the base of segment, CS,DS,ES,SS,FSor GS.

启用分页时，页面表格用于翻译线性地址到物理地址.

When Paging is enabled, the page tables are used to translate linear address to physical address.

另一方面，物理地址是只不过，地址值出现在处理器的引脚上内存读/内存写操作.

On the Other Hand, Physical Address is nothing but, the address value that appears on pins of processor during a memory read/memory write operations.

InShort，我们可以说如果分页是禁用线性地址 = 物理地址

InShort, we can say if paging is disabled linear address = physical address
