Mil-std-1553 Multi-function Bus Test Card,

The MIL-STD-1553B,issued by the U.S. Department of Defense during the late 1980s,is a time division,command / response,multiplexing techniques serial military data bus. Based on its high performance,1553B is the key technique for the integration of avionics systems and data exchange network. Its'high communication quality has a great effect on the avionics system's performance. 1553B protocol was introduced into China at the end of the last century. Nowadays,it has gained extensive application not only on national defense construction but also on civil aviation communication.This thesis tries to design an interface testing emulation board which compiles with the 1553B protocol. The board provides a virtual environment for data testing of avionics equipment, and the operation of the equipment is normal or not can be judged. This thesis introduces how to design the hardware system of the test board, including the design of the FPGA, Peripheral Component Interconnection, UART, Ethernet, USB control chip, the dedicated interface for 1553 bus, SDRAM and Flash. In the software aspect, this thesis makes an improvement in the interrupt handle system on the base of existed software design, and designs the data storage of the BC, RT and BM. The software design mainly uses the SOPC technology and Nios II embedded soft core technology to reliaze it.Ultimately,this thesis presents the details of design and simulation of the important modules in the hardware and software system. The results of the verification proves the hardware system is reasonable and the software system is applicable.
