The data prefetching auxiliary circuit includes a stride calculating circuit, a comparing module, a stride selecting module, and a prefetching output module. The stride calculating circuit receives an access address to calculate and provide a stride. The comparing module receives the access address and the stride, generates a reference address based on a first multiple, the access address and the stride, determines whether the reference address matches any of a plurality of history access addresses, and generates and outputs a hit indicating bit value. The stride selecting module receives the hit indicating bit value, and determines whether to output the hit indicating bit value based on a prefetch enabling bit value. The prefetching output module determines a prefetch address according to the output of the stride selecting module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data prefetching auxiliary circuit, data prefetching method, and microprocessor","description":"The disclosure provides a data prefetching auxiliary circuit, a data prefetching method, and a microprocessor.
