Webbased lookahead prefetcher. SPP creates a signature associated with a page address by compressing the history of accesses. By correlat-ing the signature with future likely delta patterns, SPP learns both simple and complicated memory access patterns quickly.

This state-of-the-art delta prefetcher predicts irregular strides at the L2 cache [35]. SPP works by relying on the signatures (hashes of consecutive strides) observed within an OS page to index into a table that predicts future deltas. SPP uses a lookahead mechanism

SPP is a conﬁdence-based lookahead prefetcher. It creates a signature associated with a page address by com-pressing the history of accesses.

WebSignature Path Prefetcher (SPP) [21] improves VLDP design too. However, it gains performance improvement mainly by increasing the prefetcher depth, which lead to more timely prefetching. LSTMP can be more timely by issuing multiple prefetches upon one demand access, but the main performance gain comes from accuracy improvement.
