Abstract :
A single chip MPEG audio decoder which performs the decoding scheme with a direct hardware implementation approach, without programming, is presented. Based on the computation analysis of the decoder, we develop a novel design which only requires half the computational capacity of previous decoders and half the storage memory too. The chip is designed with cost-effective and simple circuitry features, and thus it provides a consumer-economical solution, especially in design time and complexity
