Description
Summary: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.
