PROBLEM TO BE SOLVED: To enable a data processor to efficiently access continuous data stored in a plurality of memory banks. SOLUTION: A data transfer request issued from the data processor to a synchronous memory is divided, by a burst transfer length unit request dividing section 11a, into a plurality of data transfer requests in which a data transfer amount can be simultaneously burst-transferred and in which a data amount to be transferred simultaneously are equal to a data amount within a single memory bank. The divided data transfer requests are assembled, by a request assembly section 111b, into data transfer request in which data transfer requests to the memory banks are combined one by one, and outputted as a plurality of new data transfer requests.
