A bandwidth control circuit includes bandwidth control units and a management unit to control each of the bandwidth control units. Each bandwidth control unit includes: a bandwidth monitor unit to monitor a bus usage bandwidth of each of the plurality of the circuit blocks; an operating period observation unit to monitor a start and an end of an operating period of each of the plurality of the circuit blocks; and a limit unit to be enabled to limit the bus usage bandwidth of each of the plurality of the circuit blocks. The management unit limits the bus usage bandwidth, corresponding to a bus average usage bandwidth and the operating period of each of the plurality of the circuit blocks.
