Communication Software Reliability Design of 1553B Bus
XU Shu-yan · OME Information · 2010
For the sake of accurate communication scheduling and avoiding harmful effect of SEU,the failure model of 1553B bus communication is given.In order to meet the requirement of communication scheduling,the way of handshake is proposed.Then the reliable software dataflow is given for SEU(Single event upset),unlike common communication software,some measures are taken such as register renewed periodically,memory voting and redundancy design.Finally,the fault injection is applied to validate.Practical results show that the design is necessary and effective.
