WebTo cope with this, there has been an abundance of work in the area of data/instruction prefetcher designs. Broadly, prefetchers predict future data/instruction address accesses and... Webdata prefetcher uses multiple histories of deltas between successive cache lines observed within an operating system (OS) page to predict the future memory accesses in other OS pages [50]. One of the key features of VLDP is that it uses multiple prediction tables and makes predictions based on different lengths of history in terms of deltas.

"WebData Prefetch Filtering [8]. SMS (Spatial Memory Streaming) is a more recent prefetcher that avoids loading useless blocks into the cache —an issue for sequential prefetching and stream buffers— at the cost of using three tables plus some extra logic [9]. Losses can also be reduced by tuning the prefetching degree or distance. Sequential " - Data prefetcher
