Abstract:
A method for performing multi-wire signaling encoding is provided in which a clock signal is encoded within symbol transitions. A sequence of data bits is converted into a plurality of m transition numbers. Each transition number is converted into a sequential symbol number from a set of sequential symbol numbers. The sequential symbol number is converted into a raw symbol that can be transmitted over a plurality of differential drivers. The raw symbol is transmitted spread over a plurality of n wires, wherein the clock signal is effectively embedded in the transmission of raw symbols since the conversion from transition number into a sequential symbol number guarantees that no two consecutive raw symbols are the same. The raw symbol is guaranteed to have a non-zero differential voltage across all pairs of the plurality of n wires.
