6-2 TLB Management MMU manages address translation and memory protection functions in page units. MMU uses a translation table for the management in page units. Logical addresses, physical addresses and memory protection information are registered in the table. This table is called the translation look aside buffer (TLB). The TLB operates on the same clock as the CPU. For that reason it is configured as a small buffer. The TLB structure is the same as cache, direct map, set associative and full associative.
