Abstract:

1553B bus is extensively used in the military field, but the detection equipments for 1553B bus devices cannot meet the actual demands absolutely. In order to facilitate the data communication between computers and 1553B bus devices and improve the detection efficiency of 1553B bus devices, a detection system for 1553B bus devices is designed based on ARM and FPGA. The integrated design idea of the system is given firstly, and the hardware and software design methods are introduced in detail. By using the modular method, the ARM module, the FPGA module and the interface are designed independently. The ARM module implements the USB and Ethernet interfaces. By using the top-down method, the 1553B protocol IP core is implemented on FPGA. Besides, the peripheral circuits and the power module are optimized. Simulation and verification are carried out. The results indicate that the receive and send functions are designed and conform to the design specification. Finally, the practical testing on the hardware platform achieves effective results, proving that our design can meet the actual demands.
