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.

A fine-grained bandwidth control arbiter manages the shared bus usage of the requests of the masters which have real-time and/or bandwidth requirements, moreover, the masters are preset a ticket respectively. The arbiter consists of three components, a real-time handler, a bandwidth regulator, and a lottery manager with tuned weight. The real-time handler grants the most urgent request. The bandwidth regulator handles the bandwidth allocation and blocks the requests of masters that have met the bandwidth requirement. The lottery manager with tuned weight stochastically grants one of the contending masters according to the ticket assignment.
