Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China)Star sensor is one of the important components of autonomous navigation attitude control system. As the core component of star sensor, information processing system has important influence on the performance of star sensor. A nationally produced information processing system for multi-field-of-view star sensor based on the architecture of Feiteng multi-core DSP and Fudan micro FPGA is designed in this paper. In the design, EMIF and GPIO interface are used to interact and control data with Fudan micro FPGA. Two serial Flash chips are used to store star database data and start programs, and two DDR3 chips are used to cache data. The whole software process design, algorithm process design and implementation of the information processing system are introduced in detail in this paper. After experimental verification，the system can operate stably and output the correct attitude. When the star map resolution is 2048×2048, the system has an update frequency of 20Hz for data without initial pointing, while the update frequency is 625Hz with initial pointing. The computing performance is about 3 times that of the ordinary ARM architecture, which is of great significance for improving the real-time performance of the multi-field-of-view star sensor and enriching its engineering implementation method.
