Abstract:
1. A digitally configurable multiplexer/de-multiplexer, comprising: a plurality of multiplexers, each receiving a plurality of address signals, selecting from among a plurality of first data signals, and coupling a selected first data signal to a corresponding one of a plurality of multiplexed signals; a switch matrix having a first interface coupled to said plurality of multiplexed signals and a second interface coupled to a plurality of second data signals; configuration logic receiving a plurality of selection signals and coupled to control said switch matrix to couple selected ones of said plurality of multiplexed signals to said second interface; and wherein said plurality of multiplexers comprises M multiplexers, each receiving N address signals and coupling a selected one of 2N first data signals to a corresponding one of M multiplexed signals in which N, M, Y=LOG 2M and N are positive integers, and wherein said configuration logic controls said switch matrix to configure said M multiplexers as a number M/(2Y−X) of (M/2X)(2N):1 multiplexer(s) in which X is a selected integer between 0 and Y.
