An arithmetic processing apparatus includes a first data storage unit, two-dimensional arithmetic unit, and main control unit. The first data storage unit stores data to be processed. The two-dimensional arithmetic unit performs two-dimensional operation. The main control unit controls the two-dimensional arithmetic unit. The two-dimensional arithmetic unit includes an input address calculation unit which calculates the addresses of a set of input data necessary for a designated type of operation in the first data storage unit in accordance with an execution start instruction which designates the type of operation and a parameter from the main control unit, and an arithmetic execution unit which performs the designated type of operation for the set of input data which are stored at the calculated addresses in the first data storage unit.
