摘要
An efficient synthesis filter is presented which can carry out realtime MPEG-2 audio decoding. The proposed algorithm reduces the number of MBC operations by adopting novel IDCT and windowing schemes, exploiting a multichannel structure, and implementing CGD techniques. The DSP implementation is MPEG-2 compliant and achieves real-time processing with 60% reduction in runtime compared with a fast ISO decoder.
