小波變換是圖像處理領(lǐng)域的一種重要的處理方法，但是，小波變換過程中巨大的運
算量卻使得它在實時圖像處理領(lǐng)域中的應(yīng)用受到了限制。本文提出了一種基于FPGA實現(xiàn)的高速小波分解的方法，詳細分析了各個模塊的設(shè)計和時序，經(jīng)過QuartusⅡ軟件的仿真和綜合，并在Altera公司的UP3開發(fā)板上進行了驗證和性能分析。

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.
