A fuzzy-based power-aware routing algorithm for network on chip

Network-on-chip (NoC) is being proposed as a scalable and reusable communication platform for future embedded systems platforms. In this paper a novel routing algorithm for avoiding congested areas using a fuzzy-based routing decision is proposed.The routing path is established by minimizing a cost which is calculated by fuzzy controller and considers the power consumption and free slots input buffer of the neighbor cores. The proposed routing scheme can effectively regulate power distribution to meet power balance requirement and avoid hotspot with low hardware overhead.
