Abstract: Hardware data prefetching is a well-studied technique to bridge the processor-memory performance gap. Bit-pattern-based prefetchers are one of the most promising spatial data prefetchers ...

Abstract: Temporal prefetching, where correlated pairs of addresses are logged and replayed on repeat accesses, has recently become viable in commercial designs. Arm’s latest processors include ...

Hi there, I would like to understand why gem5 does not include the simplest and most commonly used instruction prefetching strategy, namely a next-line prefetcher. Its behavior is to prefetch the next ...
