PROBLEM TO BE SOLVED: To enable a data processor to efficiently make access to continuous data stored in a plurality of memory banks. SOLUTION: A first data transfer request from the data processor to a synchronizing memory is divided into a plurality of data transfer requests having a data quantity to be burst transferred at once, and which are in a single memory bank by a burst transfer length unit request dividing part 111a. The divided data transfer requests are assembled into data transfer requests where data transfer requests to each memory bank are combined one by one by a request assembly part 111b. When the data transfer requests to be combined are insufficient, a second transfer request is received and divided, and reassembled into data transfer requests where data transfer requests to each memory bank are combined one by one, and output as a plurality of new data transfer requests.
