Implementation of 1553B Communication Protocol Based on FPGA

In order to reduce the weight and volume of aviation equipment, improve system versatility and reduce costs, avionics are becoming more and more integrated. Aviation integrated electronic system, usually using a data bus structure, so that each processing unit, information transmission and control display subsystems for the various tasks shared, which the U.S. Department of Defense developed the MIL-STD-1553B protocol is commonly used in a bus communication method. At present, there are two kinds of 1553B bus communication methods, one is realized through a dedicated 1553B protocol chip, but the 1553B protocol chip on the market is expensive and poor portability; the other is realized through the FPGA 1553B protocol to complete the communication, which only takes up a small portion of the resources of the FPGA, the cost is low, and the portability is high; this paper adopts the latter approach, using the VERILOG language to realize the communication protocol design, has good practicality.
