Fault-Tolerant Application-Specific Network-on-Chip Design using Discrete Particle Swarm Optimization

This paper presents a meta-heuristic based technique Discrete Particle Swarm Optimization (DPSO) to address the permanent link failures in Application-Specific Network-on-Chip (NoC) design. Application-specific NoC based designs are more flexible with the current application requirements. With the advent of technology, dense integration of components on a chip gradually degraded the reliability and system performance. Therefore, to improve the reliability and system performance in application-specific NoC design, the proposed technique places the spare links in the likelihood of link faults. Experimentations have performed for different application benchmarks to leverage the efficiency of proposed technique. The results show that overhead in communication cost over fault-free result is minimum.
