Example:
1. Create VP_MAP tables for translating virtual addresses H'10000 to H'10fff to physical
addresses H'4000000 to H'4000fff and virtual addresses H'11000 to H'11fff to physical
addresses H'0 to H'fff.
>vs 10000 10fff 4000000 (RET)
>vs 11000 11fff 0 (RET)
>vd (RET)
<VADDR_TOP> <VADDR_END> <PADDR_TOP>
00010000 00010fff 04000000
00011000 00011fff 00000000
DISABLE
2. Then, enable the VP_MAP tables. (When the tables are disabled, addresses are not
translated.)
>ve enable (RET)
>vd (RET)
<VADDR_TOP> <VADDR_END> <PADDR_TOP>
00010000 00010fff 04000000
00011000 00011fff 00000000
ENABLE
Here, virtual addresses correspond to physical addresses as shown in figure 7.46.
