A Design of 1553B Remote Terminal System Based on FPGA

With the rapid development of science and technology and integrated circuits, information intelligence has become a new trend in the development of weapons and equipment. 1553B communication bus is widely used in various fields, most of the traditional 1553B bus depends on the 1553B protocol chip, there are expensive, poor flexibility, complex processor interface protocol, not conducive to development and other characteristics. In this paper, the realization of 1553b bus on FPGA is studied. The basic communication function of 1553B remote terminal is realized by using FPGA, which is equipped with bus transceiver chip and coupling transformer. In this paper, the remote terminal IP core built by FPGA is designed in detail according to the function module, and the function of the whole remote terminal system is verified by simulation. Through the communication test between board level and bus controller, the correctness of the commonly used 1553B message communication is verified. The test results show that the 1553B remote terminal system based on FPGA has achieved the expected goal, and can respond correctly to the instructions issued by the bus controller, complete the sending and receiving of messages, and has certain application value.
