Performance evaluation of torus and mesh in 3D network-on-chip

As three-dimensional integrated circuit(3D IC) is a chief tendency of integrated circuit,network-on-chip(NoC) is widely discussed to solve the interconnection problem of 3D IC.It is very important to choose a proper topology in 3D NoC.The paper evaluates the communication performance(transport latency and throughput) and area overhead of two kinds of conventional topological structures(torus and mesh) in NoC by mathematical analyses and software simulations.When the packets inject into NoC with the uniform distribution,using dimension-ordered routing,3D torus has better performances at throughput and transport latency than 3D mesh,but needs more area overhead.
