摘要
根据天文导航系统数据量大、实时性要求高、数据接口多的特点,设计了由2片定点型DSP TMS320C6416和2片浮点型DSP TMS320C6711组成并行的MIMD系统用作天文导航数据处理平台,其中TMS320C6416完成通讯、随动控制解算、灰度图像处理和指令处理,TMS320C6711完成星历计算、天文解算和星点亚像素提取。该平台具有体积小、功耗低、重量轻等特点,能有效提高天文导航系统图像处理能力、系统实时性和数据输出率,具有功能强大、运算能力强、实时性好的特点。
The celestial navigation system has the features of large amount of data, real-time requirement and more data in- terface. A parallel MIMD system of celestial navigation data processing platform is designed by 2 fix-point type DSP TMS3320C6416 and two floating-point DSP TMS320C6711. Communication control settlement, gray image processing and processing instructions are finished in TMS3320C6416. Ephemeris calculation, astronomical calculation and star sub pixel extraction are completed in TMS320C6711. The platform has the advantages of small volume, low power consumption, light weight, and which can effectively improve the celestial navigation system image processing capability, real time calculation a- bility and data output rate. It is a system with strong operation ability and good real-time characteristics.
