Abstract PROBLEM TO BE SOLVED: To provide a new data processing apparatus that reduces the processing time for node resynchronization.SOLUTION: A data processing apparatus 130 includes receiving circuitry 220 to receive a snoop request sent by a source node 160 in respect of requested data, and transmitting circuitry 230. Cache circuitry 240 caches at least one data value. The snoop request includes an indication as to whether the requested data is to be returned to the source node and, when the at least one data value includes the requested data, the transmitting circuitry transmits a response to the source node including the requested data in accordance with the indication.SELECTED DRAWING: Figure 3 【課題】ノードの再同期のための処理時間を軽減する新たなデータ処理装置を提供する。【解決手段】データ処理装置１３０は、要求されたデータに関してソースノード１６０から送られたスヌープ要求を受信する受信回路２２０と、送信回路２３０とを備えている。キャッシュ回路２４０は、少なくとも一つのデータ値をキャッシュする。上記スヌープ要求は、その要求されたデータをソースノードに返送するかどうかの指示を含み、上記少なくとも一つのデータ値がその要求されたデータを含む場合、上記送信回路は、上記指示に応じて、その要求されたデータを有するソースノードに応答を送信する。【選択図】図３
