System and Method to Account for I/O Read Latency in Processor Caching Algorithms

摘要

A processor includes a cache memory and a cache controller. The cache controller fetches first data from a first location of an information handling system, stores the first data to a first cache line of a plurality of cache lines, determines first proximity information for the first data based upon the first location, stores the first proximity information in a first proximity tag associated with the first cache line, and evicts the first cache line from the cache based upon the first proximity tag.
