Abstract

Power characteristics of different Network on Chip (NoC) topologies are developed. Among different NoC topologies, the Butterfly Fat Tree (BFT) dissipates the minimum power. With the advance in technology, the relative power consumption of the interconnects and the associate repeaters of the BFT decreases as compared to the power consumption of the network switches. The power dissipation of interswitch links and repeaters for BFT represents only 1% of the total power dissipation of the network. In addition of providing high throughput, the BFT is a power efficient topology for NoCs.
