Each of the memory accesses has an associated memory access type (MAT) of a plurality of predetermined MATs. The processor also includes a table that holds first scores that indicate effectiveness of the first prefetcher to prefetch data with respect to the plurality of predetermined MATs and second scores that indicate effectiveness of the second prefetcher to prefetch data with respect to the plurality of predetermined MATs. The first and second prefetchers selectively defer to one another with respect to data prefetches based on their relative scores in the table and the associated MATs of the memory accesses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiple data prefetchers that defer to one another based on prefetch effectiveness by memory access type","description":"A processor includes a first prefetcher that prefetches data in response to memory accesses and a second prefetcher that prefetches data in response to memory accesses.
