ABSTRACT:
A method for generating a modulo Gray-code representation of a non-power-of-two set of binary values begins by determining a desired Gray-code sequence length. The method then continues by determining a bus width, M, in bits, based on the desired Gray-code sequence length, to represent the generated Gray-code. The method then continues by determining a set of skipped binary values based on the desired Gray-code sequence length and the bus width to obtain the non-power-of-two set of binary values. The method then continues by representing the non-power-of-two set of binary values as a set of equivalent Gray-code values.
