摘　　要：针对GIF图像数据使用的可变长度编码的LZW压缩算法,讨论了GIF图像解码的硬件实现方法,在硬件设计中通过减少读写RAM的次数来降低解码功耗.实现的GIF图像硬件解码器经EDA工具测试和MATLAB验证,可以完全无失真地解码GIF图像.This paper discusses a hardware implementation for GIF image decode within LZW compression algorithm of which its word length is alterable during the decode process. The power dissipation of the decode process is reduced by decreasing the times of accessing RAM. The result after a series of strict tests by EDA tcols and matlab shows that this hardware decoder works very well without any distortion.
