Exploiting ECC Redundancy to Minimize Crosstalk Impact

Signal integrity in high-speed bus designs is put at risk by crosstalk-related-bus delays. This article provides a comprehensive study of the usefulness of error-correcting code (ECC) redundancy in reducing such delays. It shows that dual Rail codes perform better at this task than Hamming codes. We analyze the impact of different ECCs on crosstalk-induced-bus delays (CIBD). We investigate the possibility of exploiting the information redundancy previously necessary to limit CIBD, thus reducing the consequent risk of a systemʹs incorrect operation.
