Description: In the MP3 codec designs, prior to the MDCT and IMDCT are two reverse calculation of the most complex parts. Proposed a new algorithm for MDCT and IMDCT implementation of optimized, greatly reduces the computational complexity. MDCT and IMDCT of the algorithm is divided into three steps to achieve the calculation of: pre-processing, core processing, post-processing. Among them, core processing in part by the MDCT and IMDCT share, greatly reducing the demand on the hardware circuit and reduce the cost of the chip.
