Bitstream Buffer in Audio Coprocessor White Paper

This paper explains compressed audio bitstream buffer implementation in an audio coprocessor to handle MPEG-1 Layer 3 (MP3) bitstreams. This paper provides hardware and firmware partitioning of bitstream buffer to address low power, and low gate count requirement in audio coprocessor and at the same time being capable of decoding different types of compressed audio streams like MP3 and MPEG-2/4 Advanced Audio Coding (AAC).
