Web(BOP) [3], which was the best performing prefetching tech-nique in the 2nd Data Prefetching Championship. The key difference of BOP with respect to the previous proposal is achieving timely prefetches with a prefetch degree of one, that is, issuing a single prefetch per cache access. BOP ﬁnds the Webarea of data prefetching with deep lookahead and improved timeli-ness [8,11,13,14]. These proposals typically design delta predic-tors that can lead to a prefetch sequence.

WebData prefetching has been proposed as a technique for hiding the access latency of data referencing patterns that defeat caching strategies. Rather than waiting for a cache miss to initiate a memory fetch, data prefetching anticipates such misses and issues a fetch to the memory system in advance of the actual memory reference.
