    摘要: A branch/prefetch judgement portion, in receipt of a branch request signal, sets a cache access mode switch signal to an nullHnull level. Thus, a cache memory operates in the 1-cycle access mode consuming a large amount of power. In receipt of a prefetch request signal, the branch/prefetch judgement portion sets the cache access mode switch signal to an nullLnull level. Thus, the cache memory operates in the 2-cycle access mode consuming less power.
