A single-chip implementation of the Dolby AC-3 multichannel audio coding algorithm is presented. AC-3 is a high-quality, low bit-rate coding technique for 5.1-channel audio. This paper describes an efficient implementation of the algorithm on a powerful new DSP chip, the Zoran ZR38000. Specific areas in which the chip architecture has been exploited to optimize the algorithm are discussed, and contrasted with an equivalent implementation on a multichip platform using standard DSP technology.
