摘要 针对空间遥感图像压缩的具体应用,给出了基于CCSDS[1]算法的高速图像压缩核的设计和实现。对CCSDS算法的实现方法进行了优化,算法的VLSI架构设计充分利用了流水和并行技术,使处理速度相比串行方式平均提高了40倍。压缩验证系统实验结果表明压缩核在编码效率、处理速度和容错能力上均具有较高的性能,50MHz频率下压缩核的数据处理速度可达12.5Mpixels/s。 For the application of onboard remote sensing image compression, this paper presents a high speed and high performance image compressor for future spacecrafts and micro-satelhtes. The hardware solution proposed here exploits a modified CCS- DS algorithm and the processing speed is improved 40 times by using parallel architecture and pipeline technique. The experimental results indicate that this core has high performance at coding efficiency, data rate and error containment. A data rate of about 12.5Mpixels/s can be sustained at 50MHz.
