Webbased lookahead prefetcher. SPP creates a signature associated with a page address by compressing the history of accesses. By correlat-ing the signature with future likely delta patterns, SPP learns both simple and complicated memory access patterns quickly.

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.

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.
