摘要
由于系统芯片中IP核数目的逐渐增大,片上通信结构逐渐成了整个SoC的性能瓶颈,基于共享总线的SoC通信结构具有无法克服的局限性,这就对传统的共享总线片上通信系统提出了严峻的挑战。文中全面综述了近些年片上通信系统方面的研究,分析了共享总线,交叉开关,点到点,片上网络NoC(Network on Chip),混合互连五种片上通信结构的优缺点,以及对整个系统芯片性能的影响.最后指出片上通信研究的方向。
With the increasing number of IP cores, the communication architecture on chip is the bottleneck for SoC performance, the shared bus on chip has some limitations that can＇t be solved, and these become the challenge to the traditional SoC communication architecture. This paper summarizes the SoC communication system＇s research and development, and analyzes five communication architectures： share bus, crossbar, point- to- point, Network on Chip, hybrid Interconnect. The paper also analyzes the performance of different architecture. At last, the research directions of SoC communication on chip are discussed.
