segmented address造句
例句與造句
- Technically, the " flat " 32-bit address space is a " tiny " memory model for the segmented address space.
- For instance, the segmented address 06EFh : 1234h ( here the suffix " h " means hexadecimal ) has a segment selector of 06EFh, representing a segment address of 06EF0h, to which we add the offset, yielding the linear address 06EF0h + 1234h = 08124h.
- For example, the linear address 08124h can have the segmented addresses 06EFh : 1234h, 0812h : 0004h, 0000h : 8124h, etc . This could be confusing to programmers accustomed to unique addressing schemes, but it can also be used to advantage, for example when addressing multiple nested data structures.
- The relocation address is determined by the MBR, but it is most often 0000 hex : 0600 hex ( for MS-DOS / PC DOS, OS / 2 and Windows MBR code ) or 0060 hex : 0000 hex ( most DR-DOS MBRs ) . ( Even though both of these segmented addresses resolve to the same physical memory address in real mode, for Apple Darwin to boot, the MBR must be relocated to 0000 hex : 0600 hex instead of 0060 hex : 0000 hex, since the code depends on the DS : SI pointer to the partition entry provided by the MBR, but it erroneously refers to it via 0000 hex : SI only . ) While the MBR code relocates itself it is still important not to relocate to other addresses in memory because many VBRs will assume a certain standard memory layout when loading their boot file.
- It's difficult to find segmented address in a sentence. 用segmented address造句挺難的
