Abstract: Huffman decoding is the keystone for the advanced audio coding,the efficiency of decoding and memory requirement is important. The paper discusses various methods lor Huffman decoding, selects appropriate methods and optimizes the MIPS and memory requirement for ARM platform,this makes an 10% improvement in the MIPS and reduces the memory requirement largely.
