Abstract

処理を実行するための実行スレッドとデータのキャッシュメモリへの先読みを実行するためのデータ先読みスレッドとを並行して実行し、かつ、実行スレッドを実行する処理系とデータ先読みスレッドを実行する処理系とが共通のキャッシュメモリにアクセスするシステムにおいて、データ先読みスレッドでのデータ先読み処理の間隔を設定する。入力値を用いて実行スレッドの所要時間を予測して、その予測した所要時間に基づいてデータ先読み処理の間隔を設定するか、または、実行スレッドの処理進行状況とデータ先読みスレッドの処理進行状況を比較し、その比較した結果に基づいてデータ先読み処理の間隔を設定する。このようにデータ先読み処理の間隔を設定することにより、実行スレッドとデータ先読みスレッドとの間のメモリアクセス競合を低減し、かつ、実行スレッドとデータ先読みスレッドとの間の所要時間のバランスをリアルタイムに維持することができる。
