一种高吞吐低延时NoC容错路由算法

A High-Throughput and Low-Latency Tolerant Routing Algorithm for NoC

为了提高片上网络(Network-on-Chip,NoC)系统的可靠性及故障情况下的网络性能,基于转弯模型(Turn Model)的思想对现有的XY路由算法进行了改进,提出了一种容错路径短,且在故障情况下具有信息均衡能力的无虚通道容错路由算法(TXY路由算法)。OPNET仿真结果表明,该算法与同类算法相比具有较好的吞吐及时延性能。

To improve reliability and network performance under fault conditions for the Network-on-Chip （Network-on-Chip, NoC） system, the idea based on Turn Model makes improvement of the current XY routing algorithm and puts forward a no virtual channel fault-tolerant routing algorithm （T-XY Routing Algorithm）. The algorithm has the short fault-tolerant path and the ability to balance the information. The OPNET simulation results show that this algorithm has better performance of throughput and latency compared with the similar algorithms.
