片上网络的星型簇结构通信能耗研究

Communication energy-aware research of star cluster NoC

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3DSCBM-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,3DSCBM-NoC的通信能耗明显降低。

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.
