摘要

在JPEG2000中，采用9/7和5/3滤波器实现DWT算法。本文提出了一种可折叠的可重构结构，可用于9/7或5/3滤波器。它很简单，可以减少硬件的使用。此外，它在二维DWT1中使用效率很高。

A reconfigurable architecture for DWT and IDWT in JPEG2000

In JPEG2000, 9/7 and 5/3 filters are adopted to realize DWT algorithm. In this paper, we proposed a folded reconfigurable architecture which can be used to 9/7 or 5/3 filter. It is simple and can reduce hardware usage. Further, it is efficient to be used in 2D DWT1.
