Expert Prefetch Prediction: An Expert Predicting the Usefulness of Hardware P…

Hardware prefetching improves system performance by hiding and tolerating the latencies of lower levels of cache and off-chip DRAM. An accurate prefetcher improves system performance whereas an inaccurate prefetcher can cause cache pollution and consume additional bandwidth. Prefetch address filtering techniques improve prefetch accuracy by predicting the usefulness of a prefetch address and ba…
