基于维序路由的片上网络容错机制设计

Design of fault-tolerant mechanism based on dimension-ordered routing for NoC

文章提出了一种基于维序路由的容错设计,通过使用双模数据发送来减少发送数据的传输延迟,采用维序路由达到通信延时的优化。在搭建的8×8网格结构中,该机制的有效性得到了验证。实验结果表明,相对于端到端检错重传容错方案,基于维序路由的双模冗余容错路由方案在注入故障率为10-1时数据的传输延时降低了约40%,同时吞吐量增加了约33%。

This paper aims to propose a fault-tolerant design based on dimension-ordered routing.The design reduces the transmission delay of the transmitted data by using dual-mode data transmission,and optimizes the communication delay by using the dimension-ordered routing.The effectiveness of this mechanism is verified in the built 8×8 grid structure.The experimental results show that the dual-mode redundant fault-tolerant routing algorithm based on dimension-ordered routing outperforms the end-to-end error detection retransmission algorithm.When the injection failure rate is 10-1,the data transmission delay is reduced by about 40%,and the throughput increases by about 33%.
