This letter presents a novel implementation for Bus-Invert Coding called No Invert-Line Bus-Invert Coding (NIL-BIC) architecture. It not only removes the invert-lines used in previous BIC implementations, but sends the coding information without additional bus-transitions. NIL-BIC can save about 50% more bus-power than the implementations using invert-line.
