Abstract:

We study the applications of discrete Walsh transform in the design of digital multiplexer networks, and
propose a computer aided design theory and an algorithm of the multiplexer networks based on the Walsh
spectral techniques. We also present a practical application example, which shows that the algorithm can
minimize or nearly minimize the multiplexer tree-type network, and that the method is effective and suitable
for computer aided design of multiplexer tree-type networks. By using CMOS circuits, the 1-of-4 multiplexer
module and the designed multiplexer network with minimal size are realized. HSPICE simulation results show
that the designed circuit has correct logic functions.
