Interconnect fabrics of multi-core systems - on-chip are confronted with increased crosstalk effects and energy dissipation. Crosstalk avoidance coding (CAC) is a promising way to reduce the coupling capacitance of the interconnect wires. We propose a method to address both crosstalk and energy dissipation in networks-on-chip (NoC) by modifying the structure of the data packets and reducing the number of coding-decoding operations. Our results show that by incorporating crosstalk avoidance coding (CAC) schemes in the NoC data stream it is possible to save a significant amount of energy while communicating between multiple IP cores.
