Abstract :
As the technology scales down, the increased wire aspect ratio and the reduced spacing between the individual wires within a bus result in increased cross-coupling capacitances. This increases crosstalk noise and power dissipation particularly in wide data buses. We propose an efficient encoding scheme that eliminates correlated switching (coupling transitions) in 4-bit buses and also minimizes self-transitions among the wires in these data busses. Wider data busses are implemented using these 4-bit bus blocks.
