Abstract
Power consumption of a semiconductor device is reduced. A semiconductor device according to an embodiment includes a plurality of circuits, a bus circuit including a plurality of buffers that temporarily store communication data between the circuits and a plurality of arbitration circuits that arbitrate an access between the circuits and the buffers, a storage unit that stores information based on a use state of the buffers during communication between the circuits and configuration information including designation of unused circuits that are not used for the communication from among the circuits, and a control circuit that controls the bus circuit so as to stop use of unused buffers that are not used for the communication from among the buffers and at least a partial configuration in arbitration circuits corresponding to the unused circuits from among the arbitration circuits based on the configuration information.
