Dynamical sequentially-controlled low-power multiplexer device

Abstract

Multiplexers are basic components widely used in VLSI designs. Switching activities of a multiplexer are one of the most important factors of power consumption. A multiplexer may have some sub-multiplexers. An extra dynamic controller is applied in the present invention to reconfigure control signals for decreasing switching activities of the composed sub-multiplexers. Thus, the power consumption of the multiplexer is reduced to achieve higher power efficiency.
