Methods and systems for high bandwidth chip-to-chip communications interface

A method comprising:

• receiving a set of N signals corresponding to N elements of a code word, the elements of the code word comprising a set of at least three values, the code word representing a set of n input bits, wherein n is an integer greater than 1 and N<2n;
• operating on the N received signals using a set of n+1 comparators and responsively forming a set of n+1 comparator outputs based on the received signals, wherein at least two comparators receive a common signal of the received set of N signals;
• and,
• decoding the set of n+1 comparator outputs into a set of n output bits representing the n input bits.

A method comprising:

• receiving a set of n input bits representing information, wherein n is an integer greater than 1;
• generating elements of a code word based on the received set of n input bits;
• and, for each element of the code word:
• forming a respective pair of driver signals corresponding to a value of a respective element of the code word, wherein at most one driver signal of the respective pair can be high at any time;
• and,
• generating a signal level on a respective output wire of a set of output wires based on the respective pair of driver signals.
