Bus interconnection on deep submicron (DSM) technologies incur significantly larger power dissipation due to coupling capacitance between adjacent bus wire. This paper proposed an adaptive driver scheme to adjust the voltage on the wire in real time according to number of errors detected on a dedicated sensitive wire. Energy cost on the long inter-connection can be reduced without the degradation in the noise performance. Specifically, for an 8-bit and 16-bit buses in 65nm CMOS technology, we present a solution that reduces the energy dissipation and achieve similar noise performance.
