Patent ID: 8019968

Claim:
A method for retrieving data from an L2 cache, comprising: receiving an effective address of memory to be accessed from a level 2 (L2) cache; transmitting the effective address to a translation look-aside buffer (TLB) to retrieve a stored real address associated with the effective address; using a first set of effective address bits as an index into a real address array to retrieve trial real address bits; using bits of the trial real address to at least initiate access the L2 cache; comparing the trial real address bits to bits in the real address retrieved from the TLB; if the trial real address bits and real address bits retrieved from the TLB match, completing the access using the trial real address; and if the trial real address bits and real address bits retrieved from the TLB do not match, completing the access using the real address retrieved from the TLB.
