Abstract :
This paper discusses methods to implement the IMDCT filter bank, noiseless decoder, inverse quantiser and scale factor application modules of MPEG-2 advanced audio coding decoder more efficiently when implemented on FPGAs. The efficiency of the algorithms has been validated through implementation on Xilinx Virtex II FPGAs.
