片上网络容错路由算法分析和评价

Analysis and Evaluation of Fault-tolerant Routing Algorithms for NoC

片上网络技术是借鉴并行分布式计算机及传统计算机网络的概念解决片上多核系统的通信问题。片上网络代替片上总线通信,解决了片上总线结构所引起的可扩展性、效率、面积、功耗等问题。然而,片上网络在数据传输过程中可能由于各种原因产生故障,因此片上网络可靠性研究是当前一个研究热点。首先总结了片上网络故障分类,比较和分析了当前片上网络容错算法并给出其优势和缺陷,最后对全文进行总结,并给出了片上网络容错算法的展望。

Borrowing ideas from the concept of parallel distributed processing system and traditional computer networks,Network-on-Chip technology solves the problems of multi-core SoC.NoC takes the place of the bus on the SoC to solve the reliability,power consumption,area,efficiency which caused by the bus.However,NoC may result in the faults when it transmits the data.So the reliability of network on-chip is a hot topic currently.This paper summarizes the classification of the network on-chip faults,analyzes and compares the fault-tolerant algorithms meanwhile,points out the advantages and disadvantages of these algorithms.Then the paper gives a conclusion.finally presents future works about fault-tolerant routing algorithms on NoC.
