The Design And Realization About Manchester Yard Encoder Of MIL-STD-1553B Bus

In recent years, our country has already begun to adopt MIL-STD-1553B standard protocol in the R&D of military facilities such as new fighter plane, destroyer, etc... But, the key technology of this standard is monopolized by American-European Company, It seem more important to research and develop chip and relevant product which are based on 1553B bus standard protocol independently. To realize this goal, we must finish the code, decoding of Manchester yard at first. This paper mainly introduced how to use the programmable logical device CPLD to realize 1553B bus interior interface Manchester code encoder. The groundwork of this thesis is to use the programmable logic device CPLD to realize encoder of Manchester within MIL-STD-1553B bus interface.1553B takes one kind of military standard, it has carried on the strict standard and the restraint to the electricity and the protocol characteristic of data bus, and it has already widely used in the aviation electron system. This standard propose a series of requests to the digital bus technology which are obligatory to the aviation airplane numeral /Order/ response, time sharing multiple use , including the data bus and the interface 's electricity guide line\ the operation concept, as well as multiple data bus information flow and function form.This article first introduces the history and the procreant reason of the 1553B bus protocol, especially its widespread application in aviation data transmission...
