Abstract

　本発明は、ＭＰＵとＤＳＰの双方を備えた電子機器、および、ＭＰＵとＤＳＰの双方を備えた電子機器内で実行されてＭＰＵとＤＳＰに負荷を分散させる負荷分散プログラムに関し、新たなハードウェアを追加する必要がなく、かつ電力消費をできるだけ抑えつつ処理能力を高めることを目的とし、ＤＳＰでの処理用にコーディングされて搭載されているＤＳＰ用アプリケーションのうちの今から実行すべきＤＳＰ用アプリケーションと、クロック生成部から現在出力されているクロックの周波数とに基づいて、ＤＳＰの負荷を予測し、予測された負荷に応じて、今から実行すべきＤＳＰ用アプリケーションの一部の処理をＭＰＵに振り分けてその一部の処理をＭＰＵに実行させる。
