Considering the gradual increasing of store stations and available types of stores, and the low transfer velocity and limited remote terminal numbers of traditional MIL-STD-1553B Multiplex Data Bus in airborne avionics system and weapon system, a new data bus named enhanced bit rate 1553(EBR-1553) data bus was introduced.This paper expatiated EBR-1553 data bus from the topology architecture, hardware configuration, transfer characteristics and bus transfer model.Then the applied field of EBR-1553 was addressed.Finally, the method of EBR-1553 data bus hardware implementation based on FPGA IP core was proposed.
