The UTLB is used for the following two purposes:
1. To translate a virtual address to a physical address in a data access
2. As a table of address translation information to be recorded in the ITLB in the event of an
The UTLB is so called because of its use for the above two purposes. Information in the address
translation table located in external memory is cached into the UTLB. The address translation
table contains virtual page numbers and address space identifiers, and corresponding physical page
numbers and page management information. Figure 6.6 shows the UTLB configuration. The
UTLB consists of 64 fully-associative type entries. Figure 6.7 shows the relationship between the
