Description

technical field [0001] The invention relates to the technical field of integrated circuit design interconnection bus, in particular to a MIL-STD-1553B bus protocol controller. Background technique [0002] With the rapid development of microelectronic technology and computer technology, various bus technologies are constantly enriched and perfected. The data bus is the medium for exchanging data and information between different systems. In the avionics system, more types of hardware interfaces are needed to connect various avionics-specific electronic equipment. With the continuous improvement of the complexity of the avionics system, a large number of cables are needed to connect the equipment. These cables occupy more space inside the equipment, increase the weight of the entire system, and make it very complicated and confusing; Line maintenance and testing costs will increase dramatically. [0003] MIL-STD-1553B bus technology was originally applied in the field of mi...
