Communicating data from sensors such as gyroscopes and accelerometers, to processors, typically occurs over printed circuit board traces. This communication can cost up to 40 μW at data rates of 1 Mb/s. VDBS encoding reduces signal transitions and thus reduces the dynamic power dissipation of sensor communication. Because they require no decoder logic, VDBS-enhanced sensors can be used with unmodified existing processors and can leverage existing serial interface standards. We present vdbs2rtl, a tool for generating RTL for the optimal VDBS encoders in both VHDL and Verilog.
