INFORMATION PROCESSING APPARATUS AND CONTROL METHOD

To provide an information processing apparatus capable of suppressing the wasteful use of consumption power while exhibiting performance, and a method of control.SOLUTION: An information processing apparatus comprises a processor that is allowed to take a plurality of stages of power control modes different in rated power, a power control section that controls consumption power of the processor, and a mode setting section that, when the consumption power satisfies a transient condition to a power control mode higher in level of rated power than the current power control mode of the processor, reduces the maximum power of the processor to lower power and executes mode-transition confirming to determine whether or not to make transition of the power control mode of the processor to the power control mode higher in level based on an operation status of the processor.SELECTED DRAWING: Figure 4 【課題】性能を発揮しながら消費電力の浪費を抑えることができる情報処理装置および制御方法を提供する。【解決手段】定格電力が異なる複数段階の電力制御モードをとりうるプロセッサと、プロセッサの消費電力を制御する電力制御部と、消費電力が、プロセッサの現在の電力制御モードより定格電力が多い上位の電力制御モードへの遷移条件を満たすとき、プロセッサの最大電力をより低い電力に低下させ、プロセッサの動作状況に基づいて当該プロセッサの電力制御モードを前記上位の電力制御モードに遷移させるか否かを判定するモード遷移確認処理を実行するモード設定部と、を備える。【選択図】図４
