摘　　要：为满足MBI模块小型化、轻型化、低功耗、高可靠性和灵活性的要求,设计一块采用TI公司小型DSP处理器SM320F2812作为处理器、DDC公司小型化BU61865芯片作为协议芯片,采用FP-GA实现主要逻辑的双路、双余度、双通道MBI。该MBI能极大地减小总线负载,提高总线传输效率。Mini-ACE使得MBI具有总线控制器、远程终端、总线监控器、组合远程终端和选择消息监控等功能。通过在系统单位的综合与联试,该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, this paper design a new MBI module, which adopts mini DSP processor SM320F2812 of TI Corp. as the processor, BU61865 of DDC as the 1553B protocol processor,and uses FPGA to realize the main logic circuit. The MBI module has two redundant channels. The module is capable to minimize the payload of the bus, to improve the bus transmission efficient. It 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, we are happy to get the result that the MBI module well satisfies the requirements of high speed and flexibility.
