Abstract: A method of controlling a master device includes, providing a measured service level by measuring a service level with respect to requests of a master device that is connected to a slave device through an interconnect device and generates the request to demand services from the slave device and controlling a power level of a request control circuit included in the master device based on the measured service level. Power consumption of the master device and the system including the master device is reduced without performance degradation by controlling the power level of the request control circuit adaptively based on the measured service level.
