摘要
MPEG-2 Advanced Audio Coding (AAC) is the widely used audio standard and offers the high-quality multi-channel surround audio. In the AAC, the filterbank is the most important part in MPEG-2 AAC audio coding. It occupies the high computation load in decoding flow and can't be solved efficiently by a simple architecture. This paper presents an effective architecture that is suitable for VLSI implementation. It performs the IMDCT with dynamic windowing and overlap-add algorithm and can reduces the cost and memory storage efficiently.
