Description
Claims (5)
- 取得したデータに対して実行する処理の内容を決定するための基準となる基準データを記憶し、保持可能なデータ数よりも前記基準データのデータ数の方が少ない場合、最終データ位置から降順に前記基準データを格納して残りのデータに0を格納する第1記憶部と、
前記データの中に前記基準データが含まれているか否かを、前記データと前記基準データとを比較することにより検索する検索部と、
前記検索部による検索結果と前記処理の内容とを対応づけて記憶する第2記憶部と、
前記検索結果に基づいて、前記検索結果に対応づけられた処理を前記データに対して実行する処理部と、を含み、
前記検索部は、
検索を実行する前に、前記第1記憶部に記憶された複数の基準データを3以上の範囲に分割したとき、前記基準データと比較すべき比較対象データがそれらの範囲のうちいずれに属するかを判定する判定回路と、
前記データの中から前記基準データと比較すべき比較対象データの位置を検出する位置検出回路とを含み、
前記位置検出回路は、前記比較対象データの位置を特定するための位置特定データと前記データとを比較する第2比較回路を複数含み、前記複数の第2比較回路に前記データを所定のデータ長ずつ位置をずらして入力し、前記位置特定データと同時に並列して比較し、
前記位置検出回路は、通信パケットの全てのデータの取得を待たずに、前記データと前記位置特定データの比較を開始する
ことを特徴とするデータ処理装置。 - 前記検索部は、ワイヤードロジック回路により構成され、
前記ワイヤードロジック回路は、前記比較対象データと前記基準データとをビット単位で比較する第1比較回路を複数含むことを特徴とする請求項1に記載のデータ処理装置。 - 前記第1記憶部は、前記データ中の比較対象データの位置を示す情報を更に記憶し、前記検索部は、前記位置を示す情報に基づいて前記比較対象データを抽出することを特徴とする請求項1又は2に記載のデータ処理装置。
- 前記第1記憶部又は前記第2記憶部は、外部から書き換え可能に設けられることを特徴とする請求項1から3のいずれかに記載のデータ処理装置。
- 請求項1から4のいずれかに記載のデータ処理装置を複数備え、
それぞれの前記データ処理装置は、通信回線との間でデータを入出力するインタフェースを2つ備えており、それぞれの前記インタフェースの入力と出力を切り替えることにより、前記データを処理する方向を可変に制御されることを特徴とするデータ処理装置。
