Abstract
A memory optimization method for a MP3 decoder. In a pipeline structure for speeding matrix calculation in Mp3 decoding, an output sequence of IMDCT calculation is altered so that matrix calculation is activated before completing the IMDCT calculation. A decoding control method allows pipeline processing in MP3 decoding, with decoding procedures for subsequent granules activated while the current granule is still being processing in the matrix calculation.
