Abstract

Based on the standard MIL-STD-1553B bus military aviation description, this paper detailed analyses the character type of transmission protocol, information transmission format, and the internal registers and RAM resources of 1553B RT interface chip BU-61580 is described. The designs of hardware interface and software of the bus based on the BU-61580 and 32-bit SPARC V8 processor is introduced, and achieved the high reliability data communication between the 1553B terminal RT and bus controller BC.
