Abstract
Encoders and decoders for encoding and decoding data according to a coding scheme. The encoder converts N bits of input data into M voltage signals for transmission over M parallel wires to a decoder having one or two decoding stages that recover the N bits of data from the M voltage signals. The coding scheme is an N-bit, M-wire PAM-Q code in which each voltage signal whas one of Q voltage levels l-l, where l<l< . . . <l, and the different sets of M voltage signals for the different N-bit input values are permutations of a single set of M voltage signals. The decoder has a comparator stage. For the decoder having one other decoding stage, the other decoding stage is a computation stage or a logic stage that is before or after the comparator stage.
