CPS1432交换芯片的串行RapidIO互连技术

Serial RapidIO Interconnect Technology of CPS1432 Switch Chip

RapidIO技术是世界上第一个、也是目前唯一的嵌入式系统互连国际标准(ISO/IEC18372),串行RapidIO是针对高性能嵌入式系统芯片间和板间互连而设计的。本文介绍了CPS1432交换芯片与P2020组成的星型拓扑网络结构,包括硬件设计方案和软件设计要点,对高性能嵌入式互连设计具有很好的借鉴意义。

RapidIO technology is the world’s first as well as the only international standard of embedded systems interconnection （ISO/IEC 18372）currently.Serial RapidIO is designed for interconnection between chips and boards of the high performance embedded sys-tem.This paper introduces a network architecture with star topology based on CPS1432 switch chip and P2020,including hardware de-sign scheme and software design main point,it has good reference to the interconnect design of high performance embedded system.
