The cpu uses two units to transform the logical address into physical addresses Cpu使用两种单元将逻辑地址转换成物理地址。
The logical address is usually used when requesting information from a controller 逻辑地址通常在请求控制器中的信息时使用。
Figure 3 shows the graphical representation to obtain the linear address from logical address 图3展示了从逻辑地址获得线性地址。
The physical address may be different from the logical address , in which case the memory management unit translates the logical address into a physical address 物理地址可能与逻辑地址不同,内存管理单元可以将逻辑地址转换成物理地址。
Because we use the non - programmable register , gdt or ldt is not referred to while the translation from the logical address to the linear address is performed 由于我们使用了不可编程寄存器,因此在将逻辑地址转换成线性地址时不引用gdt或ldt 。
In computing, a logical address is the address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program.
