ABSTRACT:
A method an apparatus is provided to generate a gray code sequence from a sequence of binary values having a length “L”. Accordingly, one aspect of the present invention provides a circuit comprising a cycle flag toggle circuit configured to toggle a cycle flag between a first value and a second value, an intermediate value generator coupled to an output of the cycle flag toggle circuit configured to receive the binary value, and configured to generate an intermediate value from the cycle flag and the binary value, and a binary to gray converter coupled to an output of the intermediate value generator, configured to convert the intermediate value to a gray code.
