摘　　要：集成工控机箱使用CPCI接口兼容各种可插拔板卡,板卡的CPCI设计多使用专用芯片搭配FPGA实现,降低了可扩展性,增加了板卡面积和成本。为了解决上述问题,设计了一种基于FPGA的CPCI接口。介绍了使用FPGA实现的CPCI协议、仿真及外部通信总线协议、外部中断机制、冲突避免机制,该设计在量产的各种CPCI板卡中使用,用于各种厂家的CPCI机箱。与传统实现方案相比,该方案具有成本低、体积小、灵活性好、兼容性高等优点,在小型工控领域内具有明显的优势。The integrated industrial control chassis is compatible with all kinds of pluggable boards using CPCI interface.The CPCI design of board card uses special chips to match the FPGA,which reduces the extensibility,and increases the area and cost of the card.In order to solve these problems,a CPCI interface based on FPGA is designed.This paper describes the CPCI protocol implemented with FPGA,simulation and external communication bus protocol,external interrupt mechanism,and conflict avoidance mechanism.This design is used in various CPCI cards produced by the mass production,and it is used in the CPCI chassis of various manufacturers.Compared with the traditional implementation scheme,the scheme has the advantages of low cost,small size,good flexibility and high compatibility.It has obvious advantages in the field of small industrial control.
