| Notes | 31-1289/TP YANG Renzhong;ZHANG Jie;WEI Hongwei;SHI Lu; （1. Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences ,Beijing 100094 ,China; 2. University of Chinese Academy of Sciences, Beijing 100049,China） According to the features of downlink data of Landsat8 as well as the RICE lossless data compression algorithm and the CUDA programming technology,a real-time decompression processing system bsed on Graphic Processing Unit（ GPU） is proposed. It adopts Compute Unified Device Architecture（ CUDA） and pipelined decompression structure for task decompression and CUDA optimization. Experimental results showthat the speed-up of the implemented decompression system is 7. 45 times that of the CPU-based solution,and the processing rate is at least1. 8 times as high as that required by Landsat8 satellite downlink data real-time decompression. The decompressed image data has high accuracy with lowcost. lossless data compression algorithm; real-time decompression; Graphic Processing Unit（GPU）; satellite |
