【摘要】 提出了一种基于双缓冲和XYX路由的容错机制.该机制通过使用双缓冲存储数据包来减少数据发送的等待延时,并采用XYX路由算法缩短路由路径,达到通信延时和功耗优化的目的,实现数据的高可靠高效率传输.通过System C所搭建的4×4的2D-Mesh网络平台验证了该机制的有效性,实验结果表明,基于双缓冲和XYX路由的容错机制相对端到端随机路由算法具有更低的延时和功耗,当失效率小于2%时,数据的传输延时和功耗开销可分别降低约50%和20%.更多还原

【Abstract】 This paper proposes a fault-tolerant mechanism based on dual-buffer and XYX routing.The mechanism reduces the delay by dual buffer and optimizes the power by XYX routing strategy,which can achieve better performance in the condition of high reliability.System C is used to program the NoC router and build the 4×4 2D mesh NoC platform for verifying the validity of the fault-tolerant mechanism.The results show that the data transmission delay and power consumption overhead of this mechanism were reduced by approximately 50% and20% compared to end-to-end random routing algorithm when the failure rate is less than 2%.更多还原
