Bilinear Algorithms and VLSI Implementations of Forward and Inverse MDCT with Applications to MP3 Audio
SUMMARY Lehigh University has developed bilinear algorithms to compute forward and inverse modified discrete cosine transforms (MDCT/IMDCT) for a complete solution to MP3 audio processing. By using this technology, the multiplication operation along the critical path is minimized, allowing for 20%-30% faster computing than existing solutions. Thi...
