Description: 在MP3 编解码器的设计中,前向MDCT 与反向IMDCT 是两个计算最为复杂的部分。
提出了一种新的算法,对MDCT 与IMDCT 的实现进行优化,极大地降低了运算量。该算法将
MDCT 与IMDCT 的计算分成三步实现: 前处理, 核心处理, 后处理。其中,核心处理部分由
MDCT 与IMDCT 共用,大大减少了对硬件电路的需求,降低了芯片成本。-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.
