Address-correlating prefetcher
Tag: correlation-prefetcher
Aliases: Markov prefetcher, correlation-based prefetcher, GHB delta correlation
A prefetcher that learns repeating relationships between addresses (or deltas) — such as 'address Y follows address X with high probability' — and issues prefetches by replaying the recorded successors. Often implemented with a Markov-style table or a Global History Buffer (GHB) walked via per-key linked lists.
