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.
