TLB

Short for translation look-aside buffer, a table in the processor��s memory that contains information about the pages in memory the processor has accessed recently. The table cross-references a program��s virtual addresses with the corresponding absolute addresses in physical memory that the program has most recently used. The TLB enables faster computing because it allows the address processing to take place independent of the normal address-translation pipeline.

Also referred to as the address translation cache, a typical TLB contains anywhere from 64 to 256 entries.
