N2 - 3D NoC-based architectures have emerged to reduce the network latency, the energy consumption and total area in comparison to 2D NoC topologies. However, they are characterized by various trade-offs with regard to the three dimensional structure and its performance specifications. In this paper, we present a 3D NoC mesh architecture called Lasio, whose latency and the throughput achieved, for both network and application, are evaluated considering two types of traffic patterns, varied buffer depth and a range of packet sizes. Cycle-accurate simulations demonstrated that there is a high impact of buffer depth and packet size on the NoC latency and on the application latency. Applying an appropriate buffer depth, for several sizes of packets, the application latency is reduced and throughput is increased.
