Scalable codeword generation for coupled buses

Abstract

Inductive and capacitive coupling are responsible for slowing down signals. Existing bus encoding techniques tackle the issue by avoiding certain types of transitions. This work proposes a codeword generation method for such techniques that is scalable to very wide buses. Experimentation on a recent encoding technique confirms that the conventional method is limited to 16-bit bus while the proposed method is easily extended beyond 128-bits.
