Abstract: Networks-on-Chip (NoC) is recently proposed as an alternative to the on-chip bus to meet the increasing requirement of complex communication needs in Systems-on-Chip (SoC). Most researchers advocate the use of traditional regular networks like meshes as architectural templates which gained a high popularity in general-purpose parallel computing. However, most SoC platforms are special-purpose tailored to the domain-specific requirements of their application. They are usually built from a large diversity of heterogeneous components which communicate in a very specific, mostly irregular way. In such systems the size and nature of cores may vary quite widely making the topology irregular. Moreover regular topologies can become irregular due to faults in links and switches. In such scenario topology agnostic routing algorithms are generally required. In this paper, we have analyzed the performance and applicability distributed table based routing for irregular NoC on an Network-on-Chip simulation framework.
