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 tables
