Performance analysis and comparison of 2 × 4 network on chip topology

The performance analysis and comparison of 2 × 4 network on chip (NoC) topology are mainly presented in this paper. Firstly, three common 2 × 4 topologies, 2D Mesh topology, 2D Torus topology and hierarchical Mesh topology are designed. Secondly, the performances of three topologies are analyzed and compared in detail by using NoC performance evaluation standard. Finally, the occupying resources of three topologies are also compared. The result shows that 2D Torus topology can achieve higher throughput and lower average network latency in occupying fewer resources.
