4.2 Address Spaces
32-bit Mode Address Translation
Figure 4-2 shows the virtual-to-physical-address translation of a 32-bit mode address.
- The top portion of Figure 4-2
shows a virtual address with a 12-bit, or 4-Kbyte, page size, labelled Offset. The remaining 20 bits of the address represent the VPN, and index the 1M-entry page table.
The bottom portion of Figure 4-2 shows a virtual address with a 24-bit, or 16-Mbyte, page size, labelled Offset. The remaining 8 bits of the address represent the VPN, and index the 256-entry page table.
