WebFeb 5, 2024 · Experimental evaluations show that LSP improves the memory system performance with no prefetching by 66%, and the improvement over the state-of-the-art prefetchers, Access Map Pattern Matching Prefetcher (AMPM), Best-Offset Prefetcher (BOP) and Signature Path Prefetcher (SPP) is 26.6%. 21.7% and 27.4%. respectively. WebSignature Path Prefetcher Table Updating • When L2 access a page, the corresponding signature table will update - Offset update - Offset difference (delta) use to generate new signature - The old signature is used for modifying pattern table Same pattern will have same signature • Reduce training time and PT store entries

PDFCM (Prefetching basedon a Differential Finite Context Machine) is a selective correlating prefetcher that we developped in [3]. The prefetching degree in the L2 cache is adaptive, but the mechanism is new, based on 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). SPP works based on the des moines weather cameras
