Abstract

Virtual channels are a common alternative for providing quality-of-service to Networks-on-Chip. A drawback of the approach is the increased power consumption because of the suppression of correlation between consecutive flits. This work proposes an architecture based on low-power coding to overcome the aforementioned problem. The technique requires a minimum overhead, while obtaining a significant power reduction (45% in the average case). Exhaustive experimental simulations are provided to demonstrate the advantages of the proposed architecture.
