Crosstalk Avoidance using Fibonacci Code Word for Sub Micrometer on Soc Application

Srinivas Rao. G, P. M. Francis, B. Prasad Kumar

Abstract: In this paper we are proposing the long bus wire connection and cross correlation principals that provide the Propagation delay across long on-chip buses is significant manner when adjacent wires are transitioning in opposite direction (i.e., crosstalk transitions) as compared to transitioning in the same direction. By exploiting Fibonacci number system, we propose a family of Fibonacci coding techniques for crosstalk avoidance, relate them to some of the existing crosstalk avoidance techniques, and show how the encoding logic of one technique can be modified to generate code words of the other technique.
