基于软硬件协同设计的Huffman解码模块

摘要

With the rapid development of multi-media technology,digital audio technology also developed rapidly.MP3 is a lossy audio compression format with high compression rate,at present in many fields it has begun to widely used with good market prospects.This paper is mainly based on hardware and software co-design approach to implement the Huffman decoding module of MP3.The solution proposed in this paper can not only efficiently realize the Huffman decoding module of MP3 but also be applied to the Huffman decoding module of WMA,AAC and other audio formats,The approach ensure efficient while taking into account the module＇s versatility.%随着多媒体技术的迅猛发展,数字音频技术也快速发展起来。MP3是一种有损音频压缩编码,其压缩程度很高,目前在很多领域已经开始广泛应用,具有良好的市场前景。主要基于软硬件协同设计的方法,实现MP3的Huff-man解码模块。提出的解决方案不仅可以实现对MP3的Huffman模块的高效解码,同样也可以应用于WMA、AAC等其他音频格式的Huffman模块,在保证高效的同时,兼顾了模块的通用性。
