This state-of-the-art delta prefetcher predicts irregular strides at the L2 cache [35].

VLDP stores the history of deltas to predict future deltas. SPP is a state-of-the-art delta prefetcher that predicts the non-constant (irregular) strides (commonly known as deltas).

Hardware prefetching is an impor-tant feature of modern high-performance processors [19]. SPP prefetches by dynamically updating the entries in the signature tables and pattern tables. They record the information of the last 256 visited pages and the count of ionized water for cleaning windowsWebSignature 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. on the basis of vs based on
