片上网络拓扑结构的研究

随着SoC体系结构设计复杂度的提高,传统的总线结构已成为IP核之间通信的瓶颈。为了满足大规模集成电路发展对扩展性、能耗、面积、时钟异步、重用性、QoS等方面的需求,新的设计方法—片上网络(NoC)应运而生,它是对原有设计模式的一次革新。本文分析了NoC的技术特点以及在该领域中的关键技术,详细地对NoC中常见的拓扑结构进行了分类研究,并指出了每种拓扑结构中的优点与不足;然后通过分析每种拓扑结构的性能参数,从而对其性能进行综合的比较。

Research of Network on Chip Topology

With the complexity of designing SoC architecture increasing,traditional bus-based architecture has become the bottleneck of communication among IP blocks. In order to meet the requirements of scalability,energy consumption,size,clock asynchronization,reusability,QoS etc in large-scale integrated circuits,the new design method-network on chip (NoC) came into being,which is a new innovation compared to the original design patterns. In this paper,first,we introduced the technical characteristics in NoC and the key technology in this area; Then we study the common NoC topology in detail and point out the advantages and shortcomings of each one; Finally,By analyzing the performance parameters of each topology,we can get integrated performance comparison.
