一种基于分层Mesh网络的层次化NoC拓扑结构
A Hierarchical NoC Topology Based on Layered Mesh Network
摘要
Abstract
Communication delay increases sharply with the expansion of distance between the nodes in the network on chip.In order to solve this problem,this paper proposes a Hierarchical Diagonal Mesh(HDMesh) topology.The topology adopts hierarchical design.The base-level is connected by Mesh for the communication between adjacent nodes.On the top level,two diagonal links are added in the Mesh architecture to further reduce the communication delay.To avoid the congestion on the top level network,a Hierarchical Diagonal XY (HDXY) routing algorithm is proposed to assign the flow rate of each layer reasonably.The experimental results show that,compared with Mesh,CMesh and CHMesh in the Rent flow mode,HDMesh has lower communication latency and higher network throughput.关键词
