| 1. | 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。 |
| 2. | 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。 |
| 3. | 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。 |
| 4. | The addresses of server methods are logical and function properly in one process , but do not function in a different client process 服务器方法的地址是逻辑地址,并且可在一个进程中正常工作,但不能在其他客户端进程中正常工作。 |
| 5. | 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。 |
| 6. | 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 。 |
| 7. | As with paging , this mapping requires two memory references per logical address , effectively slowing the computer system by a factor of two , unless something is done 如同对源程序编码给予定位一样,这种变换需要每一逻辑地址有两个内存参考。如果没有什么措施,则会有效地使用计算机系统运算速度降低一半。 |
| 8. | Meanwhile it brings security problems : how to protect a " logic " group , which contains lots of machines not in a single area or internet section , as we do in unicast times 在带来方便的同时它也带来了新的安全问题:在一个逻辑地址上是一个群组但地域和网段上都没有任何逻辑关联的用户群中如何象单播那样提供安全保护? |
| 9. | As we saw earlier in the section on linux and segmentation , each segment descriptor uses same set of addresses for linear addressing , minimizing the need to use the segmentation unit to convert logical addresses to linear addresses 前面介绍linux分段模型时已提到,每个分段描述符都使用相同的地址集进行线性寻址,从而尽可能降低使用分段单元将逻辑地址转换成线性地址的需要。 |
| 10. | In a virtual - memory system , programs are given access to a larger set of addresses than is physically available , and a dedicated memory manager maps these logical addresses to actual locations , using temporary storage on disc to hold the overflow 在虚拟内存系统中,程序可以访问超出可用物理内存的更大的地址集合,专用内存管理程序将这些逻辑地址映射到实际地址,使用磁盘上的临时存储保存超出的部分。 |
