The aging policy for each region establishes an initial age value for each entry of the cache, and a particular aging policy can set the age for a given entry based on whether the entry was placed in the cache in response to a demand request from a processor core or in response to a prefetch request. The cache controller can use the age value of each entry as a criterion in its cache replacement policy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selecting cache aging policy for prefetches based on cache test regions","description":"A cache controller applies an aging policy to a portion of a cache based on access metrics for different test regions of the cache, whereby each test region implements a different aging policy.
