Configuration of the TLB
The TLB caches address translation table information located in the external memory. The address
translation table stores the logical page number and the corresponding physical number, the
address space identifier, and the control information for the page, which is the unit of address
translation. Figure 3.6 shows the overall TLB configuration. The TLB is 4-way set associative
with 128 entries. There are 32 entries for each way. Figure 3.7 shows the configuration of virtual
addresses and TLB entries.
