The Design of Spaceborne Image Compression Based on the DSP A436^TM
基于A436^TM的星上影像有损压缩系统设计

With the analysis of the status of the spaceborne Image compression, the hardware system design based on the DSP A436~(TM) is presented for the frame and broom sensors. Compared with the special encoder, the system has the adjustable compression ration and flexible compression arithmetic program. Because of the parallel procession and prevention error code diffuseness, the scheme decreases the ration of error code effectively while improving the capability of the data procession.
