摘要

提出了一种离散小波变换(DWT)的VLSI实现方法。该架构本质上是收缩的，并且仅使用一组乘法器执行高通和低通系数计算。该体系结构简单、模块化、可级联，并已在VLSI中实现。仿真结果表明，在512/spl次/612像素单色视频输入下可以实现实时系数计算。

VLSI implementation of discrete wavelet transform

This paper presents a VLSI implementation of discrete wavelet transform (DWT). The architecture is systolic in nature and performs both high-pass and low-pass coefficient calculations with only one set of multipliers. The architecture is simple, modular, and cascadable, and has been implemented in VLSI. Simulation results show that real-time coefficient calculation on a 512/spl times/612 pixels monochrome video input can be achieved.
