Floorplanning exploration and performance evaluation of a new Network-on-Chip

The Network-on-Chip (NoC) paradigm has emerged as a revolutionary methodology in current System-on-Chips (SoCs) for integrating a large number of processing elements in a single die. It has the advantage of enhanced performance, scalability and modularity, compared with previous bus-based communication architectures. Recently, A new Triplet-based Hierarchical Interconnection Network (THIN) has been proposed. In this paper, we explore the three-dimensional (3D) floor-planning of THIN and present two different floorplanning and routing methods using both the Manhattan routing and the Y-architecture routing architectures. A cycle-accurate simulator is developed based on Noxim NoC simulator and ORION 2.0 energy model. The latency, power consumption and area requirement of both THIN and Mesh are evaluated. The experimental results indicate that the proposed design provides 24.95% reduction in average power consumption and 16.84% improvement in area requirement.
