摘　　要：为满足GJB289A接口小型化、轻型化、低功耗、高可靠性和灵活性应用需求,设计一款采用SM320F2812作为智能处理器、SM61864芯片作为GJB289A控制芯片,采用FPGA实现主要逻辑的双余度双通道MBI。MBI能极大降低总线负载,提高总线传输效率。SM61864使得MBI具有BC、RT、Monitor、RTMT等功能。通过在线综合与联试,MBI模块能够满足系统的快速、灵活等要求。To meet the requirements of minimization,low -power,high -credibility and flexibility of MBI module,a new MBI module is designed in this paper,which uses the mini DSP processor SM320F2812 of TI Corp.as the processor,BU61865 of DDC as the GJB289A protocol processor and FPGA to realize the main logic circuit.The MBI module has two redundant channels and is capable to minimize the payload of the bus to improve the bus transmission efficient.The mini -ACE can be used as the bus controller,remote terminal,bus monitor and the combination of remote terminal and select message monitor.After the integration in the system -design institute,the MBI module satisfies the requirements of high speed and flexibility.
