Proactive instruction fetch
Webb1 juli 2024 · In particular, Fetch Directed Prefetching (FDP) is an effective technique to mitigate frontend stalls since it leverages existing branch prediction resources in a processor and incurs very little hardware overhead. Modern processors have been trending towards provisioning more frontend resources, and this bodes well for FDP as it… View … WebbInstruction Prefetching Smruti R. Sarangi . Menu.

Webb4 nov. 1997 · RAS-Directed Instruction Prefetching (RDIP), which associates prefetch operations with signatures formed from the contents of the RAS, which achieves 70% of the potential speedup of an ideal L1 cache, outperforms a prefetcher-less baseline by 11.5% and reduces energy and complexity relative to sequence-based prefetching. 54 PDF WebbWe propose Proactive Instruction Fetch, an instruction prefetch mechanism that achieves higher than 99.5% instruction-cache hit rate, improving server throughput by 27% and nearly matching the performance of a perfect L1 instruction cache that never misses.
Webb11 dec. 2013 · RDIP achieves 70% of the potential speedup of an ideal L1 cache, outperforms a prefetcher-less baseline by 11.5% and reduces energy and complexity relative to sequence-based prefetching. RDIP's performance is within 2% of the state-of-the-art Proactive Instruction Fetch, with nearly 3X reduction in storage and 1.9X reduction in … WebbMore recently, Proactive Instruction Fetch [5] increases RDIP’s performance by capturing the blocks accessed by the committed instructions and instruc-tions from handlers for OS interrupts. Hence, it operates on the correct-path, retire-order instruction stream, and records the exact instruction fetch sequence which is then used to
WebbRDIP's performance is within 2% of the state-of-the-art Proactive Instruction Fetch, with nearly 3X reduction in storage and 1.9X reduction in energy overheads. AB - L1 instruction fetch misses remain a critical performance bottleneck, accounting for up to 40% slowdowns in server applications.
