Abstract: As size of chip is becoming smaller with growth in technology, and due to increase in number of cores, system-on-chip (SoC) becomes very complex. Networkon- chip (NoC) provides best solution to SoC by reducing communication overhead. The basic concern of NoC is the speed, performance and accuracy along with the small size of chip. The existing NoC topologies such as mesh topology, bus topology, torus topology, fat tree topology does not provide optimized performance. In this paper, we have proposed communication-based cluster topology (CBCT), which is based on 2H, i.e., heterogeneous and hybrid, proves to be more efficient topology by providing better performance due to reduction in latency, link utilization and energy consumption involved during communication. In experimental result, CBCT approach is compared with 2D mesh topology and CBCT proves to provide better results in terms of an end-to-end latency, network latency, packet latency, sink bandwidth, loss probability, link utilization and energy consumption of a topology.
