A control apparatus includes functional modules and an arbitration unit. Each functional module includes a memory capable of transitioning, per a control signal, between a first power state and a second power state consuming lower power than the first power state. The arbitration unit performs control to cause a power state of the memory of one of the functional modules to make a transition. Each functional module receiving a request for power state transition of the memory makes an inquiry of whether the power state of the memory can transition to another state. In response to the inquiry, the arbitration unit issues a permission for transition of the power state of the memory of one of the functional modules. The functional modules that have received the permission from the arbitration unit control the control signal input to the memory, to make the transition of the power state of the memory.
A control apparatus comprising:
A power saving control method for a control apparatus having a first control signal output unit configured to output a first control signal, a second control signal output unit configured to output a second control signal, a plurality of first memories, a plurality of second memories, and an arbitration unit, the power saving control method comprising:
