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.

Webbeen used in our submission, namely: Signature Path Prefetcher and Perceptron-based on-line learning. 2.1 Underlying prefetcher The original Signature Path Prefetcher [1] was proposed by Kim et. al. SPP is a conﬁdence-based lookahead prefetcher. It creates a signature associated with a page address by com-pressing the history of accesses. WebDec 1, 2024 · Signature Path Prefetcher (SPP)[17] computes compressed signa-tures to index predicted deltas, and controls the prefetch degree according to the probability calculated through the prefetch path. SPP uses sequences consisting of five deltas to capture patterns accurately in theory. However, the accuracy decreases because the
