With the IEEE-1394 successfully applied in aviation field,IEEE-1394 has become a member of avionics bus. In order to solve the 1394 bus in the application of avionics system, meet the requirement of avionics environment, and correspond the requirement of AS5643 for certainty and reliability requirements of the 1394 bus. Introduced the design and implementation of a module based on AS5643,from hardware architecture,FPGA logic architecture and software architecture in detail,and proposed an implementation based on FPGA logic AS5643 agreement solution. According to experimental verification,the result shows that the module meets the design in-dexes,has good performance,to achieve the high transmission rate and meet the application requirements of airborne environment.
