摘　　要：阐述H.264标准中的整数反变换运算及反量化。该硬件原型包含亮度直流系数的反哈达玛变换和反量化以及亮度系数和色度系数的反变换过程。根据蝶形算法,该硬件原型采用分时复用技术和全零信号,节省运算时间。仿真结果表明,该设计能满足高清数字视频的实时处理应用。The paper introduces the inverse integer transformation and quantization in H.264. The hardware prototype is comprises by the processes of Hadamard inverse transform and inverse quantization for the luma DC coefficients as well as inverse transformation for the luma coefficients and chroma coefficients. Base on Butterfly algorithms, the hardware prototype adopts time division multiplexing （TDM） technology and all-zero signal for saving operation time. The simulations show this design can satisfy the real-time requirements for HDTV applications.
