Dia - Torus : a N Ovel T Opology for N Etwork on Chip

The shortcomings of conventional bus architectures are in terms of scalability and the ever increasing demand of more bandwidth. And also the feature size of sub-micron domain is decreasing making it difficult for bus architectures to fulfill the requirements of modern System on Chip (SoC) systems. Network on chip (NoC) architectures presents a solution to the earlier mentioned shortcomings by employing a packet based network for inter IP communications. A pivotal feature of NoC systems is the topology in which the system is arranged. Several parameters which are topology dependent like hop count, path diversity, degree and other various parameters affect the system performance. We propose a novel topology forNoC architecture which has been thoroughly compared with the existing topologies on the basis of different network parameters.
