Abstract:
An apparatus and method are described for performing history-based prefetching. For example a method according to one embodiment comprises: determining if a previous access signature exists in memory for a memory page associated with a current stream; if the previous access signature exists, reading the previous access signature from memory; and issuing prefetch operations using the previous access signature.
