摘要 相对于传统的平面结构, 三维片上网络具有更好的集成度和性能。提出一种基于三维网格的星型簇结构的片上网络(3D SCBM-NoC), 3D SCBM-NoC可以减少路由节点, 降低处理节点间的通信代价。通过分析3D SCBM-NoC的拓扑结构, 建立了针对星型簇结构的片上网络通信能耗模型, 分别使用顺序方法和蚁群算法实现了片上网络映射。实验结果表明, 相对于处理节点规模相同且数目为16的3D Mesh-NoC和2D Mesh-NoC, 3D SCBM-NoC的通信能耗明显降低。

英文摘要 Comparing with the traditional planar structure, 3D NoC are capable of achieving better performance and packaging density. This paper advanced a new style of NoC structure called star cluster NoC based on three dimensions Mesh(3D SCBM-NoC), which could reduce the number of router nodes, and saved the cost of communication. By analyzing the topology of the 3D SCBM-NoC, this paper presented the communication energy model of star-cluster structure, and achieved the mapping of NoC using the sequence method and ant arithmetic. When the number of processor nodes is 16, comparing with 3D Mesh-NoC and 2D Mesh-NoC, the communication energy of 3D SCBM-NoC is the lowest.
