%X A new lossless compression algorithm of hyper-spectral image based on 3D adaptive prediction was realized on TMS320DM642, a high performance digital signal processor of Texas Instruments Corp, By optimizing its algorithmic language and configuration, the working efficiency of the program was greatly improved. This research made significant contributions to both developing the hyper-spectral technology and promoting its application. The experimental results show the optimized program can run at the speed 18.72 times faster than that non-optimized one on DSP platform, and 2.281 times faster than the algorithm on personal computer.
