【摘要】：片上网络(networks-on-chip,NoC)是3维集成电路的主要通信技术之一.其中,路由器是3维片上网络的重要组成部件.现有的面向3维片上网络中路由器的容错技术,通常采取路由器整体冗余技术或者直接舍弃失效路由器的方法,这导致网络资源损失较为严重.提出一种面向3维片上网络的轻量级细粒度容错机制,充分利用故障路由器中仍能正常运行的有效资源,保障系统通信.提出的容错机制包括一种高可靠性路由器微体系结构设计和一种与之匹配的容错路由机制.通过实验对比和分析,相比较于已有的3维片上网络容错机制,提出的细粒度容错机制具备较高的通信性能和可靠性,同时面积和功耗开销较小.
[Abstract]:Network on chip (networks-on-chip, NoC) is one of the main communication technology of 3 dimensional integrated circuit. The router is an important component of the 3 dimensional network on chip. The existing 3 routers in the network fault-tolerant technology dimension sheet, usually take the overall redundancy router or direct discard method for failure of the router, which leads to cyber source loss is more serious. This paper presents a new approach to 3 dimensional network on chip lightweight fine-grained fault-tolerant mechanism, make full use of resources effectively the normal operation of the fault in the router, security communication system. The fault-tolerant mechanism comprises a high reliability router microarchitecture design and a matching fault-tolerant routing mechanism through the comparison and analysis, compared to network fault tolerance mechanism compared with other 3 dimensional slice, fine-grained fault tolerance mechanism proposed have high communication performance and reliability, at the same time area And the power consumption is less.
