Abstract:
1. A method, comprising: (a) buffering portions of a digital signal prior to providing the portions of the digital signal to a sub-system that is responsive to the digital signal; (b) while the portions of the digital signal are being buffered, determining, based on the buffered portions of the digital signal, when one or more portions of the sub-system and/or another sub-system can be switched from a first state to a second state, where the second state results in less power dissipation than the first state; (c) selectively switching the state of one or more portions of the sub-system and/or another sub-system, based on results of the determining performed at step (b); and (d) providing the portions of the digital signal to the sub-system so that the sub-system can respond to the portions of the digital signal.
