基于PXI/PCI总线的双MIC通讯模块设计

MIC bus,which is developed specially for solving power/data distribution and management under severe environment,is a kind of field control bus that has simple structure and provides high reliability.This paper discusses the hardware and software design scheme of double MIC bus communication model via analyzing the MIC bus architecture and protocol .The system control the mic through the design of FPGA logic and realize the communication of PC with the interface card through the CVI interface panel and PXI/PCI bus.Double MIC chip set respectively as the controller and remote mode, can complete the four work mode test of the MIC chip.This interface card which is provieded with plug and play capability and easy to use lays a solid foundation for its follow-up practicality development.
