Webreport that the STMS prefetcher produces an average memory tra c overhead of roughly 35% for a mix of commercial and scienti c workloads [42]. 4. We show that the ISB performs well when combined with a state-of-the-art stride prefetcher (AMPM) [20]. A hybrid that uses an 8 KB ISB achieves a 40.8% speedup over a baseline with no prefetching.
WebThis file describes an Instruction Pointer-based (Program Counter-based) stride prefetcher. The prefetcher detects stride patterns coming from the same IP, and then prefetches additional cache lines.
