PROBLEM TO BE SOLVED: To provide a data-processing device which executes data processing of a sub-CPU by making use of a memory connected to a memory connected to the main-CPU and a memory connected to the sub-CPU. SOLUTION: The data-processing device is provided with; a main CPU 1 which executes data processing; an external memory 3 connected to the main CPU 1; a sub-CPU 2 which executes a part of the data processing that the main CPU 1 executes; a memory 4 connected to the sub-CPU 2; and a transmission means 5 which transmits a program, which is stored in the external memory 3, to the memory 4. The main CPU 1 divides the program stored in the external memory 3 into prescribed memory sizes and controls the transmission means 5 to sequentially transmit them to the memory 4.
