| 摘 要： | 根据1996年Sweldens等人提出的提升小波变换方法,设计了一种有效的JPEG2000CDF(2,2)整数小波变换的VL-SI实现结构,并对小波系数的变化范围进行了分析。用VHDL对该结构进行基于FPGA实现的可综合描述,并用EDA软件进行了仿真和综合,硬件仿真结果和软件Matlab实现结果完全一致。

| Abstract: | Based on the lifting scheme wavelet transform firstdiscovered by Sweldens in 1996, a efficient VLSI architecture ofJPEG2000 CDF (2,2) integer- to- integer discrete wavelet trans-form is presented, and the range of CDF (2,2) wavelet coeffi-cients is analyzed. Then we describe the implementation archi-tecture based on FPGA using VHDL, The code is simulated andsynthesized using EDA software. The results of simulation com-pletely correspond with software emulators. |
