Abstract
A cache system may include a cache to store a plurality of cache lines in a write-back mode; dirty cache line counter circuitry to store a count of dirty cache lines in the cache, increment the count when a new dirty cache line is added to the cache, and decrement the count when an old dirty cache line is written-back from the cache; dirty cache line write-back tracking circuitry to store an ordering of the dirty cache lines in a write-back order; mapping circuitry to map the dirty lines into the ordering; and controller circuity to use the mapping circuity to identify an evicted dirty cache line in the ordering and remove the evicted dirty cache line from the ordering.
