从SOC到NOC的集成电路设计技术发展

From SOC to NOC:Development of IC Design Technology

遵循摩尔定律的预言,半导体集成电路工艺技术持续高速向深亚微米工艺发展,大规模集成电路设计技术是发展过程中需要解决的关键问题。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。近几年研究提出全新的集成电路体系结构NOC,是将计算机网络技术移植到芯片设计中,从体系结构上彻底解决了SOC设计技术存在的问题。因此,NOC将成为集成电路下一代主流设计技术。

According to Moore＇s law, VLSI design is the key technology to the development of semiconductor IC towards deep submicron. SOC （system on chip） design technology based on bus solved some key issues of VLSI design. However, it has some disadvantages, such as poor scalability and lower communication efficiency, etc. A new architecture NOC （network on chip） is proposed recent years, in which bus interconnection for chip is replaced by computer network interconnection. And it will overcome the disadvantage of SOC thoroughly and become a mainstream design technology for the next generation integrated circuit.
