| Abstract: | A design of MPEG audio decoder is presented. To achieve the real time decoding, a dedicated digital signal processing core is designed. The practice of state of the art hardware software codesign greatly cut the cycle time to build the digital system. The optimization of decoding algorithm reduces the computational complexity and the cost of VLSI system. |
