IC设计技术中的IP核互连:随着IC 设计复杂度的不断提高,在SoC 中集成的IP 核越来越多,基于片上总线的SOC 设计技术解决了大规模集成电路的设计难点,但是片上总线的应用带来了可扩展性差、平均通信效率低等问题。近几年来,将英特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片上网络(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。关键词:集成电路;IP;片上系统;片上总线;片上网络Abstract:With the improvement of complexity in IC design,IP reuse has become one ofthe main solution in SOC design. SOC design technology based on bus has somedisadvantages,such as poor scalability and lower communication efficiency,etc. In recentyears, a new architecture NOC is proposed, in which bus interconnection for chip is replacedby computer network interconncetion. And it will overcome the disadvantages of SOC designthoroughly and become a mainstream design technology for the next generation intergratedcircuit.Key Words:IC;IP;SOC;Bus on chip; Network on chip
