Kandou Bus uses a novel form of spatial coding to transmit data between wired chips. The main idea is to introduce correlations between the signals sent on the interface, and choose the correlations judiciously to lower the power consumption, increase the speed, and lower the footprint. It is a generalization of differential signaling (which sends correlated signals on two wires). The company is a spin-off of Dr. Shokrollahi’s lab at the Swiss Federal Technical Institute in Lausanne.
