Geng Li-hong · Jisuanji gongcheng yu sheji · 2004
Based on high-speed scientific data processing unit (SDU) in solar space telescope, the distributed managing and control design of SDU is presented. First, the distributed structure of onboard spacecraft computer is shown in detail. Second, an approach to design the data flow and control flow separately is given. The network topology, parallel communicate ability, response time and fault tolerance are analyzed. Finally, the debugging results and further discussion are presented.
