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.

WebVLDP [9] is a recent prefetcher that tracks complex address patterns. It uses a multilevel delta history to ﬁnd a more accurate match for the future accesses. Another recent work called Signature Path Prefetcher (SPP) [10] also maintains a signature for each page. These signatures are made using the delta history.
