算量却使得它在实时图像处理领域中的应用受到了限制。本文提出了一种基于FPGA实现的高速小波分解的方法，详细分析了各个模块的设计和时序，经过QuartusⅡ软件的仿真和综合，并在Altera公司的UP3开发板上进行了验证和性能分析。

Abstract: Wavelet transform has been widely used in image processing. However,
its large computational complexity limits its practical usage in real-time
systems. The paper proposes an implementation of the fast 2-D discrete wavelet
transform(DWT) based on the FPGA technology. The design and time sequence of
the module structure are described in detail. After simulation and synthesis
with the QuartusⅡ software , the design is verified on the UP3 development
board of Altera.
Key words: image processing、wavelet transform、FPGA、Verilog HDL、 QuartusⅡ
