Abstract

With data prefetching, memory systems call data into the cache
before the processor needs it, thereby reducing memory-access latency.
Using the most suitable techniques is critical to maximizing data
prefetching's effectiveness. The authors review three popular
prefetching techniques: software-initiated prefetching, sequential
hardware-initiated prefetching, and prefetching via reference prediction
