ABSTRACT:
A bussed system with a fast and compact majority voter in the circuitry responsible for the bus inversion decision. The majority voter is implemented in analog circuitry having two branches. One branch sums the advantage of transmitting the bits without inversion, the other sums the advantage of transmitting the bits with inversion. The majority voter computes the bus inversion decision in slightly more than one gate delay by simultaneously comparing current drive in each branch.
