<p><b>Abstract</b>—Maintaining a low tag array size is a major issue in many cache designs. In the decoupled sectored cache, we present in this paper, the monolithic association between a cache block and a tag location is broken; the address tag location associated with a cache line location is dynamically chosen at fetch time among several possible locations.</p><p>The hit ratio for a decoupled sectored cache is very close to the hit ratio for a nonsectored cache. Then a decoupled sectored cache will allow the same level of performance as a nonsectored cache, but at a significantly lower hardware cost.</p>
