Abstract
A mechanism is provided for providing an improved reconfigurable cache. The mechanism partitions a large cache into inclusive cache regions with equal-ratio size or other coarse size increase. The cache controller includes an address decoder for the large cache with a large routing structure. The cache controller includes an additional address decoder for the small cache with a smaller routing structure. The additional address decoder for the small cache reduces decode, array access, and data return latencies. When only a small cache is actively in use, the rest of the cache can be turned into low-power mode to save power.
