PROBLEM TO BE SOLVED: To provide a processor for reducing the time to access a main storage unit. SOLUTION: The processor includes: a processing part that has a first storage part; a second storage part that holds a part of the data held by the first storage part; a third storage part that receives, from the processing part, a first request including first attribute information for reading the data from the second storage part, and for obtaining a first logical value and a second request including second attribute information for reading the data from the second storage part, and for obtaining a second logical value which is different from the first logical value, and that holds the first request until receiving a completion notification of the first request or holds the second request until receiving a completion notification of the second request; and a control part that receives the first and the second requests from the third storage part, and replaces the first attribute information of the first request by the second attribute information when the data of the addresses corresponding to the first and second request are not in the second storage part, and supplies the completion notification for the second request to the first storage part.
