A Study of Network-on-Chip Performance

Network-on-Chip (NoC) technology was introduced by incorporating the concepts of computer networks for on-chip communication. The packet based communication has advantages over conventional bus based communication architectures. In this work we explore the performance of NoC by varying the parameters of NoC like topology, injection rate, routing algorithm, traffic pattern ...etc. We compare the throughput and latency for different configurations of NoC. From the performance analysis a mesh network with 4x4 size, number of virtual channels 4, traffic pattern as tornado and routing algorithm as dimension order routing has the low latency and high throughput.
