随着半导体器件和互连线尺寸的不断缩小,越来越多的关键设计指标--性能、抗扰度等,将受到互连线的严重影响。而在SOC设计过程中,最具特色的是IP核利用技术,随着集成的IP核越来越多,基于片上总线的SOC设计技术带来了一些问题。近几年来,将Internet网络中分层互连的思想引入到SOC设计中IP核的互连上来,提出了全新的集成电路体系结构NOC,NOC从多处理体系结构、消除时钟树以节省资源、实现并行通信等几个方面,展示了优于总线结构的本质和特性,成功地解决了SOC设计中存在的问题。
As the size of semiconductor devices and interconnects shrinks, more and more key design metrics - performance, immunity, etc., will be severely affected by interconnect lines. In the SOC design process, the most unique is the IP core technology, with more and more integrated IP core, based on the bus SOC design technology has brought some problems. In recent years, the idea of hierarchical interconnection in Internet has been introduced into the interconnection of IP cores in SOC design. A new integrated circuit architecture (NOC) has been put forward. From the multiprocessing architecture, NOC eliminates the clock tree to save resources, Achieve parallel communication and several other aspects, showing the nature and characteristics of the bus structure is superior to successfully solve the SOC design problems.
