Data Encoding Technique for Crosstalk Delay Reduction on Fault Tolerant Data-Bus in DSM Technology

Propagation delay through Fault tolerant data buses, data buses and interconnects limits the performance and reliability of a highly integrated circuits. This delay is due to crosstalk occurring on the buses or interconnects. This crosstalk is due to switching activity occurring on the Fault tolerant and interconnects when data is transmitted. Hence reducing the crosstalk delay is one of the main design challenges in DSM and VDSM technology. Reduction of crosstalk delay increases the reliability and performance of the system. One of the favourable techniques to reduce the crosstalk delay on fault tolerant data bus is to reduce the switching activity. Data encoding technique is the promising method to reduce the switching activity on the fault tolerant data bus. Hence an efficient Crosstalk delay reduction fault tolerant data bus encoding technique is proposed which can reduce the total crosstalk delay by around 36%, to 40% compared to unencoded data and 0.3% to 32% compared to others techniques for 12-bit, 21-bit, 38-bit and 71-bit data buses.
