摘　　要：提出将容错虫洞路由应用于动态片上网络DyNoC,能有效解决实时放置任务间的通信;并提出了增强型动态片上网络,增加了处理单元PE和周围路由节点Router的连线,并赋予PE自主选择路由源目节点能力,明显减少路由跳数,改善了网络的互连性.通过OPNET软件仿真,增强型DyNoC的平均端到端延迟比DyNoC缩短27%,而吞吐率则显著提高35%,可以有效缓减对片上路由资源缓存的需求.In order to solve the problem of real-time communication between dynamic reconfigurable modules, Fault-Tolerant Wormhole Routing Algorithms are proved to be effective on DyNoC and a new Improved-DyNoC is presented in this paper. In this structure, the number of connections between Router and PE is increased and the entire network connectivity is strengthened. Otherwise, rooting hops are obviously decreased as PE can decide which one to be the source or destination rooter. Finally simulated through OPNET, the average end to end delay of Irnproved-DyNoC is shorted by 27 %, while the throughput is improved obviously by 35 % compared with DyNoC.
