Abstract

　この演算処理装置は、仮想アドレスと物理アドレスとの対応を示す複数のエントリをページテーブルとして保持するメインＴＬＢと、メインＴＬＢに保持されるページテーブルの一部を保持するマイクロＴＬＢとを備える。このような構成において、演算処理装置は、メインＴＬＢに保持される物理アドレスと、当該物理アドレスに関連付けられた仮想アドレスと、アドレス変換要求に含まれるコンテキストＩＤとを対応付けてエントリとしてマイクロＴＬＢに登録し、アドレス変換要求を受信した場合に、当該アドレス変換要求に含まれるコンテキストＩＤをコンテキスト値に変換することなく、当該アドレス変換要求に含まれる仮想アドレスとコンテキストＩＤとに一致するエントリをマイクロＴＬＢから検索し、エントリが検索された場合に、エントリに含まれる物理アドレスを応答し、エントリが検索されなかった場合に、アドレス変換要求をメインＴＬＢに送信する。
