Abstract: With a method of connecting SRAMs by daisy chain connection, the power state of all the SRAMs is determined uniquely. Because of this, even in the case of an SRAM of a function module in which SRAM access does not occur, the SRAM returns to the normal mode. The control apparatus includes a plurality of function modules including a memory capable of making a transition between a first power state and a second power state that is more power-saving than the first power state in accordance with a control signal. Then, control is performed so as to output a first signal that gives instructions to make a transition of the power state based on the control signal to a memory of a function module of the plurality of function modules in which processing using a function that the function module has is performed.
