VLSI ARCHITECTURE OF SINGLE CHIP MPEG AUDIO DECODER FOR DAB

摘要

With the development of Digital Audio Broadcasting (DAB), a large number of DAB receivers will be needed, so the Application Specific Integrated Circuits in DAB receivers must be designed and fabricated. In DAB, the ISO/MPEG-Audio Layer II standard(MUSICAM) is used as the source coding algorithm. In this paper, the MUSICAM decoder is analyzed, and in order to obtain the optimum VLSI implementation for the MUSICAM decoder, a decoder hardware algorithm is developed. Base on the hardware algorithm and the tradeoff among speed, accuracy and cost, a feasible VLSI architecture of single chip MPEG audio decoder for DAB is designed and verified by VHDL/Logic simulation.
