Abstract
In the deep sub micrometer CMOS process technology, the interconnect resistance, length, and inter- wire capacitance are increasing significantly, which contribute to large on-chip interconnect propagation delay. Data transmitted over interconnect determine the propagation delay and the delay is very significant when adjacent wires are transitioning in opposite directions (i.e., crosstalk transitions) as compared to transitioning in the same direction. Propagation delay across long on-chip buses is significant 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. Keywords: On-chip bus, crosstalk, Fibonacci coding.
