Abstract
A method of performing an address lookup process in a way halting cache includes receiving a tag portion and index bits of an address for a lookup; obtaining a first set of bits from the tag portion for a preamble, wherein a second set of bits from the tag portion form a prologue; performing a first matching operation using the preamble to identify a hit in a row of a memory of the way halting cache, the row being selected by the index bits; and for any identified hit from the first matching operation, performing a second matching operation using the prologue and the index bits to finalize the hit and checking a valid bit when performing the second matching operation.
