Design of New Scalable Network on Chip Architecture using Adaptive Group based Routing Algorithm

On-chip communication architecture is the primary goal of this paper, which aims to reduce the drawbacks of earlier Network on Chip (NoC) architectures while simultaneously improving network performance. In addition, this paper work implements a new routing strategy that ensures that there is no traffic contention and no packets loss on-chip communication architecture. There are several advantages to the proposed architecture. Most existing NoC topologies are not scalable, and some are only scalable linearly; however, the proposed network is more scalable, in particular, it provides scalability in two-dimensional design space, it provides path diversity, it uses a smaller number of resources when compared to some of the earlier topologies, it provides lower latency, and it is simple to add additional groups to the network. A maximum of two hops are required for two nodes in the same group to communicate with one another. The network designed is simulated and analyzed with regard to various parameters using the OMNET++ software, and finally the final results are given, followed by a discussion of the findings. Simulation results show that for a network size of 8 clients, the total number of events varies from 95 to 107, for a network size of 16 clients, the total number of events varies from 255 to 273, and for a network size of 24 clients, the total number of events varies from 407 to 529. In a nutshell, this variance results in an increase in the number of events as well as an increase in the size of the network.
