多核处理器已经成为处理器的主流,并发展成为各种通信与媒体应用的主流处理平台。通讯结构是多核系统中的核心技术之一,核问通信的效率是影响多核处理器性能的重要指标。目前有3种主要的通讯架构:总线系统结构、交叉开关网络和片上网络。总线结构设计相对方便、硬件消耗较少、成本较低;交叉开关是适合用于构建大容量系统的交换网络结构;而片上网络是更高层次、更大规模的片上网络系统,目前可以解决多核体系结构问题,是多核系统最有前途的解决方案之一。文中在分析了NoC结构的基本原理、系统结构和功能的同时,也提供了部分单元的设计实现。
多覈處理器已經成為處理器的主流,併髮展成為各種通信與媒體應用的主流處理平檯。通訊結構是多覈繫統中的覈心技術之一,覈問通信的效率是影響多覈處理器性能的重要指標。目前有3種主要的通訊架構:總線繫統結構、交扠開關網絡和片上網絡。總線結構設計相對方便、硬件消耗較少、成本較低;交扠開關是適閤用于構建大容量繫統的交換網絡結構;而片上網絡是更高層次、更大規模的片上網絡繫統,目前可以解決多覈體繫結構問題,是多覈繫統最有前途的解決方案之一。文中在分析瞭NoC結構的基本原理、繫統結構和功能的同時,也提供瞭部分單元的設計實現。

In recent years, Multi-core architectures have been the mainstream design of the processors as well as the mainstream processing platform of various communication and multimedia applications. The communication structure becomes one of the core technologies of Multi-core processors. The efficiency of communication between the inter-core is the key indicator of Multi-core processor performance. There are three main types of communication ar- chitecture : Bus system, Cross-bar network and On-Chip Network. Bus structure designs have the advantages of con- venience, low hardware consumption and low cost. Cross-bar design is suitable for the switching network structure of building large-capacity systems. On-Chip Network is larger and more sophysicated on-chip network, which can com- pletely solve the problem of Multi-core architecture and therefore becomes one of the most promising solutions for the Multi-core system. The paper discusses the principle, system structure and function of the NOC communication ar- chitecture and presents the realization of some units.
