【摘要】 介绍了一种应用在JPEG解码器下采用并行方式实现的Huffman解码方式,这种结构的解码器把Huffman的头码流分析和解码分开工作,可以在同一时间进行解码;这种方式通过增加流水线和结构的复杂性对硬件资源的占用,来获得对码流解码的高吞吐量;它不同于传统的串行结构,将码流逐位地输入解码器中,然后解码器又通过逐位地匹配实现码流的解码。更多还原

【Abstract】 A method for the design and implementation of the parallel Huffman decoder in JPEG decoders is introduced.This architecture can run both the stream parser and the decoder,and it needs more pipelines and occupation of hardware source,but it will enhance the efficiency of decoding the codeword.This architecture is different from the traditional bit-by-bit sequential matching algorithm.更多还原
