摘　　要：传统压缩系统存在压缩效果差的问题,无法达到人们的高效压缩图像数据标准,为此,提出多维图像数据的分块无损压缩系统设计。构建压缩器硬件结构框图,采用具有层次化模块设计方法,对数据缓存元件符号和多维图像存储器模型展开分析;针对系统软件部分设计,可利用压缩算法对数据进行压缩,并使用解码器进行解码。根据具体编码流程,实现分块无损压缩系统设计;通过仿真实验,得出结论。由实验结果可知,该系统的设计具有良好图像数据压缩效果。The traditional compression system has poor compression effect,and can′t satisfy the standard of high-efficiency compressed image data.Therefore,the design of block lossless compression system for multi-dimensional image data is proposed.The hardware structure of the compressor is constructed.The hierarchical module design method is used to analyze the data cache element symbols and multi-dimensional image memory model.For the design of the system software,the compression algorithm can be used to compress the data,and the decoder is used for data decoding.The design of block lossless compression system is realized according to the specific coding process.The conclusion was obtained with simulation experiment.The experimental results show that the system design has perfect compression effect of image data.
