摘　　要：为了实现高效率的片上网络数据传输,提出了一种偏转直通片上网络框架结构。在基于交叉开关的集中式互连和基于传统片上网络的分布式互连之间进行了权衡,提出了一种基于花环网络的混合网络拓扑结构和偏转直通路由算法。该框架可以打破传统路由算法固有的缺陷,通过缩短路由路径长度提升路由效率。实验表明:与传统XY路由及拥塞感知自适应路由相比,偏转直通片上网络框架以10%的额外硬件面积开销平均提升网络饱和吞吐率84%,降低网络功耗27.3%。To achieve high-efficient data transmission, an efficient shoot-through framework architecture for network-on-chip is built, which makes trade-off between the centralized bus-based interconnection and the distributed NoC-based interconnection. Then , a torus-based hybrid network topology and shoot-through routing algorithm are proposed. The proposed framework breaks the inherent feature of conventional routing schemes that could remarkably reduce the length of routing path so as to improve the routing efficiency. Experimental results show that, compared with typical XY and congestion-aware adaptive routings, shoot- through framework with 10 % more area overheads can improve the network saturation throughput by 84 % and reduce the power consumption by 27. 3 % in average.
