Lossless non-arbitrated address-event coding

Abstract

A new address-event coding technique for off chip communication in neuromorphic and other perceptual systems is presented. Unlike all known solutions for address-event communication, our technique is able to individually identify a plurality of colliding events without arbitration thus preventing loss due to collisions. The proposed encoder is based on the error correction coding theory. The technique enables precise event timing by producing codes at a very fine time scale (e.g., Ions).
