MPEG MDCT的一些文章 A design on the vector-processor of MDCT-IMDCT algorithm for digital audio；A fast algorithm of integer MDCT for lossless audio coding

图像编码 如H263 264 AVS等编码都要用DCT变换，DCT变换IP核很有用

MDCT快速算法的定点实现和相关算法文档资料，MDCT广泛泛应用于当前主流的音频编解码算法中。，已通过测试。 -Fixed-point implementation of the fast MDCT algorithm and the documentation related algorithms, MDCT widely widely used in the current mainstream audio codec algorithm. , Has been tested.

针对图象的二维自适应MDCT滤波工具箱,很实用 推荐给大家(In view of the image two-dimensional adaptive toolbox, MDCT filtering is very practical Recommend to everyone)
