TLB Functions

3.3.1

Configuration of the TLB

The TLB caches address translation table information located in external memory. The address

translation table stores the physical page number translated from the virtual page number and the

control information for the page, which is the unit of address translation. Figure 3.4 shows the

overall TLB configuration. The TLB is 4-way set associative with 128 entries. There are 32 entries

for each way. Figure 3.5 shows the configuration of virtual addresses and TLB entries.
