Abstract

This paper presents a new routing protocol of network-on-chip(Noc) called "Source Routing for Noc" (SRN) for fault tolerant communication of Systems-on-chip(Soc). The proposed SRN algorithm is composed of two mechanisms of route discovery and route maintenance to allow nodes to discover and maintain source routes to arbitrary destinations in Noc, and all aspects of the protocol operate entirely on-demand allowing the routing packet overhead to scale automatically based on its need. The SNR algorithm in this paper demonstrates up to 50 % more fault tolerance comparing with the conventional algorithms. This new method can be easily adapted and implemented with lower cost due to less hardware overhead in SoC that integrate a large number of communicating IP cores.

片上网络的容错源路由

针对片上系统(Soc)的容错通信，提出了一种新的片上网络(Noc)路由协议“片上网络源路由”(SRN)。提出的SRN算法由路由发现和路由维护两种机制组成，允许节点在Noc中发现和维护到任意目的地的源路由，并且协议的各个方面完全按需运行，允许路由数据包开销根据需要自动扩展。与传统算法相比，本文提出的信噪比算法的容错能力提高了50%。由于集成了大量通信IP核的SoC中硬件开销较少，因此这种新方法可以很容易地适应并以较低的成本实现。
