Abstract

　監視部１３９は、複数のオペレーティングシステムを動作させるプロセッサ又は複数のプロセッサに供給される電力を制御するための電力制御命令を監視し、キャッシュエントリ設定部１４１は、キャッシュ記憶装置１１１を構成する複数のキャッシュエントリの中から置換対象となるキャッシュエントリを選択する際に、電力制御命令に基づいて変更される複数のオペレーティングシステム又は複数のプロセッサの実行状態を用いて、電力制御命令を実行したオペレーティングシステム又はプロセッサが利用していたキャッシュエントリを、過去に使用された状態に設定し、置換対象選択部１３６は、過去に使用された状態に設定されたキャッシュエントリを、置換対象となるキャッシュエントリとして選択する。これにより、複数のオペレーティングシステム又は複数のプロセッサが１のキャッシュ記憶装置を有効活用できる。
