Abstract
情報処理システム(1)のキャッシュ(20)は、プリフェッチされたデータがアクセスされたか否かを示す利用情報と、プリフェッチする原因となった命令を一意に識別する命令識別子とを対応付けて格納する利用情報格納部(20a)を備える。このような構成のもと、情報処理システム(1)は、プリフェッチされたデータの利用情報を利用情報格納部(20a)に書き込む。そして、情報処理システム(1)は、CPU(10)からプリフェッチされたデータに対してアクセスが行われた場合には、利用情報をセットする。その後、情報処理システム(1)は、キャッシュ(20)のデータが破棄される際に、破棄されるデータの利用情報を利用情報格納部(20a)から読み出す。具体的には、情報処理システム(1)は、利用情報格納部(20a)から利用情報を読み出し、利用されたか否かを判別してプリフェッチミスを検出する。
