Description

マルチメディア・プロセッサは、処理装置がアプリケーションに割り当てられた時間の割合に基づいて負荷を決定する。マルチメディア・プロセッサは、電力消費量を削減するために、負荷に基づいてクロック速度を調節する。
リソース使用量モニター装置614は、例えば各処理装置が割り当てられる時間の割合(percentage)を追跡し続けることによって、処理装置の使用量をモニターする。モニター装置614は、適切な性能を供給している間、電池電力を節約するために処理装置の処理を調節する。例えば、モニター装置614は、電力消費量を削減するために、マルチメディア・プロセッサの負荷に基づいてマルチメディア・プロセッサ120のクロック速度を調節する。更に、モニター装置614は、その処理装置の負荷、又は利用の割合に基づいて個々の処理装置のクロック速度も調節する。モニター装置614は、最大限の負荷(full loading)に対して最も速いクロック速度を選択し、次第に遅い負荷(less loading)に対して次第により遅い速度のクロックを選択する。更に、モニター装置614は、どのアプリケーションにも割り当てられない任意の処理装置を一時停止し／電力を下げ、いずれかのアプリケーションに割り当てられた時、その処理装置を使用可能にし／電力を上げる。
