Howard Mao 9d50f37289 fix unused set issue for multiple L2 cache banks 2015-11-20 23:26:28 -08:00
Howard Mao 3c95afebc6 Shift set index for multi-bank configurations
Prior to this commit, the L2 cache banks used the lower bits of the
block address as the set index. However, the lower bits are also used to
route addresses to different banks. As a result, in multi-bank
configurations, only a fraction of the sets in each bank could be
accessed. This commit fixes that problem by using the bits ahead of the
bank index as the set index, so that all sets in the cache can be
accessed.
