Even in the case where a ring bus interface that is connected to an internal ring bus of an LSI is provided as an interface of the LSI in order to add a new image processing function, the position of a function extension module on the ring bus is fixed. An information processing apparatus including: a first controller unit having a plurality of modules and a ring bus that connects the plurality of modules in the form of a ring; and a second controller unit having a plurality of modules and a ring bus that connects the plurality of modules in the form of a ring, and the first controller unit having an interface that transmits data to the ring bus within the second controller unit and a switch capable of switching an output destination of data output from at least one of the plurality of modules of the first controller unit to the interface.
