Abstract :
Dolby AC-3 and MPEG-2 audio are two different standards for the compression of up to six independent digital audio channels into a single serial bit stream. This paper describes a DSP-based integrated circuit which implements the two decoding algorithms, allowing original pulse code modulation (PCM) information to be recovered from an encoded bit stream. We mainly describe the methodology which was employed to design and validate the software embedded on the chip
