Abstract

A method of controlling a clock frequency is disclosed and includes monitoring a plurality of master devices that are coupled to a bus within a system. The method also includes receiving an input from at least one of the plurality of master devices. The input can be a request an increase to the clock frequency of the bus. Further, the method includes selectively increasing the clock frequency of the bus in response to the request.
