| 摘 要： | 提出了一种基于提升算法的连续和离散统一的小波变换算法，给出可重构的计算结构，包括可重构的提升节点阵列和地址发生器．为了验证该结构的正确性，在现场可编程门阵列平台上测试了离散的二维5/3和9／7变换（JPEG2000标准中采用）及连续的二维Hart变换，结果证明该设计具有普遍的兼容性．

| Abstract: | In this paper,a unified computation framework of discrete and continuous wavelet transform based on lifting scheme and a reconfigurable architecture that includes reconfigurable lifting step arrays and reconfigurable address generator are proposed.To validate this architecture,a FPGA prototype is developed to test the reconfiguration of 2-D discrete 5/3 and(9/7) transform(defined in JPEG2000) and 2-D continuous Haar wavelet transform.The experiment results show that this design is generic and scalable. |
