Design and Implementation of IP Core for 1553B bus test

MIL-STD-1553B is an avionics bus which is adopted widely, but the 1553B ASIC is difficult to be reprogrammed and modified. Most 1553B applications currently interface via dedicated protocol chip, such as BU-61580, resulting in inferior flexibility and high spending. In this paper, the architecture, function and realization of IP core for implementing 1553B protocol on field programmable device is discussed. The other important point is to raise the fault injection and error detection design method at the protocol layer of IP core. Finally, the experiment results show that the IP core can accord with communication protocol and realize bus test functionality.
