摘　　要：3D结构的片上网络(3D NoC)结合了3D集成(3D IC)和NoC技术的优势,相比2DNoC具有更为优越的性能。然而,目前大多数关于3D NoC结构的研究都集中在3D Mesh结构上。介绍了利用NIRGAM仿真器实现的另一种拓扑结构——3D Torus。在均衡负载模式和对称随机负载模式下分析评价了3D Torus网络延迟和吞吐率。结果表明,3D Torus拓扑结构的性能高于3D Mesh结构。Three-Dimensional Networks-On-Chip（3D NoC） architectures combine the benefits of 3D IC and NoC to offer better performance.However,most researches on architectures of 3D NoC focus on the 3D Mesh at present.This paper implemented 3D Torus,upgraded 2D NoC simulator NIRGAM for 3D topology modeling and analyzing,then evaluated latency and throughput of 3D Torus and compared it with 3D Mesh under uniform and transpose traffic patterns.The results proved that 3D Torus showed a better overall performance than 3D Mesh under most common conditions.
