Webprefetching (VLDP) [45] and signature path prefetching (SPP) [33] are well known delta prefetchers. 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).

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.

WebSignature path prefetching (SPP). This state-of-the-art delta prefetcher predicts irregular strides at the L2 cache [35].

WebOct 19, 2016 · Designing prefetchers to maximize system performance often requires a delicate balance between coverage and accuracy. Achieving both high coverage and accuracy is particularly challenging in workloads with complex address patterns, which may require large amounts of history to accurately predict future addresses. This paper … WebThe theory behind this is: RSB is a stack with depth 16 which is filled on every call. On the return path speculation "pops" entries to speculate down the call chain. Once the speculative RSB is empty it switches to other predictors, e.g. the Branch History Buffer, which can be mistrained by user space and misguide the speculation path to a gadget.
