PROBLEM TO BE SOLVED: To eliminate a bus neck between a data transfer circuit and a local memory. SOLUTION: The data transfer circuit (800) comprises a fetch circuit (801) which fetches a plurality of data transfer parameters (701) which are stored in the local memory (113) by a processor (112) for directing a DMA transfer with one bus access, a parameter storing memory (802) which stores the data transfer parameter (701) fetched by the fetch circuit (801), and a DMA transfer circuit (803) which performs the DMA transfer based on the data transfer parameter (701) stored in the parameter storing memory (802). By fetching the plurality of data transfer parameters (701) with one bus access, the bus neck between the data transfer circuit (800) and the local memory (113) can be eliminated.
