virtual-to-physical address translation, the CPU compares the
8-bit ASID (if the Global bit, G, is not set) of the virtual address to the ASID of the TLB entry to see if there is a match. One of the following comparisons are also made:
If a TLB entry matches, the physical address and access control bits (C, D, and V) are retrieved from the matching TLB entry. While the V bit of the entry must be set for a valid translation to take place, it is not involved in the determination of a matching TLB entry.
Figure 4-20 illustrates the TLB address translation process.
