| 摘 要： | 多核处理器（multi—core processor）成为高性能处理器体系结构的研究发展方向，核间的连接方式对多核处理器性能的发挥起着重要作用。从降低节点度、减少网络链路数和缩短网络直径的角度出发，提出了一种用于片上核间互连的新型分层互连网络——基三分层互连网络（THIN），该网络拓扑简单，节点度数低，网络链路数相对较少，并具有明显的层次性和对称性以及良好的扩展性。深入比较了THIN和2-D Mesh的静态度量和无阻塞延迟，比较结果表明：在网络规模较小时，THIN比2-D Mesh更宜于用来构建片上核间的通信网络。

| Abstract: | High-performance processor architectures are moving towards designing that feature multiple processing cores on a single chip.Efficient on-chip interconnection network is very essential to the performance of multi-core pro- cessor.A new interconnection network for multi-core processor,which is named triple-based hierarchical interconnec- tion network(THIN),is proposed.The topology of the network is very simple and it has obviously hierarchical,sym- metric and scalable characteristic.The interconnection network properties and latency in no-blocking mode of THIN and 2-D Mesh are compared.The compare result shows when there are not too many nodes THIN is more fit to con- struct interconnection network for multi-core processor than 2-D Mesh. |
