An Efficient High Speed VLSI Architecture for 1-level 2-D Discrete Wavelet Transform

摘要:

提出了一种针对9/7小波滤波器的二维一级小波变换的硬件平台,整体结构采用流水方式实现,数据分组输入,列变换采用多个小波变换单元,行变换模块为可重构硬件结构,行列变换之间不需要片上存储器。与已有结构相比,该结构可以通过更少的硬件资源消耗获得更高的处理速度。

Abstract:

An efficient and high speed pipeline Very Large Scale Integration(VLSI) architecture for 1? level 2?D Discrete Wavelet Transform(DWT) is proposed,of which buffer between column and row transform is not needed.Its row transform module is a reconfigurable h
