快速阿达玛变换硬件系统的设计
A Design of Fast Hadamard Transformation Hardware System
【摘要】 一个2~m×2~m阶标准阿达玛矩阵可以分解为m个相同的矩阵相乘.基于这个特点,给出了一个实际的快速阿达玛变换硬件系统.试验结果表明,该硬件系统能够在20ms之内完成像素为4095的图像变换。
【Abstract】 A 2m×2m normalized Hadamard matrix can be written as the mth power of a single matrix. Based on this property, the authors have advanced a hardware system to do fast Hadamard transformation (FHT). It is shown that the hardware system can execute FHT within 20ms for an image of 4095 pixels.
