In this paper, the authors describe a design of Ogg vorbis decoder for an embedded platform. Ogg vorbis is an audio compression format developed by the Xiph.Org foundation, a non-profit organization working in the area of Internet multimedia technology. Since ogg vorbis decoding process incurs high computational complexity, a software based implementation requires high operational frequency. Thus in their design a hardware module will be designed for high computational complex block. They aimed to implement this design using soft core processor MicroBlaze by xilinx.
