An integrated circuit includes a main processing unit, a peripheral connection port for connecting a peripheral device, and an auxiliary processing unit configured to control the peripheral connection port and to perform controlling of interruption and transmission of data from the peripheral device connected to the peripheral connection port instead of the main processing unit. The main processing section and the peripheral connection portion are connected to each other with an inner bus. The main processing unit uses a memory resource provided in the auxiliary processing unit as a part of an inner memory space of the main processing unit.
