Publication number: 20040098540Abstract: A branch/prefetch judgement portion, in receipt of a branch request signal, sets a cache access mode switch signal to an “H” 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 “L” level. Thus, the cache memory operates in the 2-cycle access mode consuming less power.Type: ApplicationFiled: July 2, 2003Publication date: May 20, 2004Applicant: RENESAS TECHNOLOGY CORP.Inventors: Teruyuki Itoh, Naoto Okumura
