What is a translation look-aside buffer? What is contained in each entry it contains?
Answer:
-A translation look-aside buffer (TLB) is a high speed cache for page table entries (that can either be virtual or part of the physical MMU) containing those that are recently used. It consists of two different entries, EntryLo and EntryHi. EntryHi contains a virtual address and sometimes ASID. EntryLo contains a corresponding physical address and a number of bits signifying whether the address is 'dirty', 'empty'
or otherwise
