Description
Summary:On-chip interconnect (OCI) plays a prime role in the entire system-on-chip performance, energy consumption, and area requirements. OCI has become a successful research field given the dramatic increase in the number of processors and other functional units (IPs) that need to be integrated on a single chip. Current systems-on-chip (SoCs) use bus- based systems which become a bottleneck because of scalability, energy efficiency and frequency limitations. New sophisticated interconnects were recently proposed as a re search direction in SoC design, including distinct topologies and specific routing and switching techniques. This paper analyzes and compares five common NoC configurations, 2D mesh, ring, spidergon, fat-tree(FT) and butterfly fat-tree (BFT). These configurations are simulated for different traffic scenarios that imitate certain application domains, and comparison results for different performance metrics are presented.
