The design of high reliable serial system BUS

With the development of astronavigation and aviation technology, the currently high-reliable serious bus can not meet the requirement fully and totally show at follow aspects: 1 low system bus speed and the bus load up to 85%; 2 low system intelligentize and the bus takes too many time of CPU; 3 imperfect preventive measure for Single Event Upset (SEU) and can not adapt space vile environment. For the short coming and future development demand, the high performance and strengthening single-chip intelligent 1553B bus controller need to be researched. It uses TOP-DOWN technique, faced to space vile environment and has independent intellectual property rights. On this basic, we have researched further key technology which impact embedded system such as SOC/SIP system integration, IP design and application and so on, and explored SOC/SIP Integration of electronic systems in space applications.
