Abstract
We report the design and implementation of a compliant MPEG audio decoder for Layers I and II with new algorithmic and architectural enhancements. The proposed algorithm uses a scaled 32-point Chen DCT and is implemented using 16-bit integer arithmetic. Measurements and results are given for a complete decoder implemented and optimized for Intel's MMX technology Author(s) Hans, M.
