Abstract

　制御回路（４０）は、電源電圧供給回路（５０）を制御し、ターゲット回路（６０）に供給する電源電圧を制御する。基準速度モニター（２０）は、ターゲット回路におけるクリティカルパスの遅延時間が、要求される動作速度を満たしているか否かをモニターする。電圧差モニター（３０）は、ターゲット回路の電源電圧とターゲット回路におけるしきい電圧との差をモニターし、電圧差情報を出力する。制御回路は、基準速度モニターでのモニター結果に基づいて、電源電圧を上げるか又は下げるかを決定する。また、制御回路は、電源電圧を変化させる際には、電源電圧制御速度が、電圧差モニターが出力する電圧差情報に比例するように、電源電圧の変化レートを決定する。
