| 摘 要： | 论文研究了二维提升结构9／7小波变换模块电路实现；通过分析小波变换过程中数据流格式及输入输出规律，指出可基于片上系统软硬件协同地完成小波变换；据此设计了基于翻转结构的一维小波变换专用处理电路用于水平方向一维小波变换；通过嵌入式软核读取中间结果，用于垂直方向一维小波变换。对标准图像的测试结果表明：平均仅需4ms-5ms时间即可完成512×512大小图像的9／7小波变换，具有较高的工程实用价值。

| Abstract: | The architecture of 2D lifting-based 9/7 discrete wavelet transform is studied. With the data flow including input and output analyzed, it＇s proposed that the transform module should be implemented based on System on Chip（SoC） via the cooperation of software and hardware. The special processing circuit of 1D horizontal transform based on the flip structure is designed, and the micro-processor is used to read the inter-result to process the 1D vertical transform. The test result using the standard image shows that only 4ms-5ms is needed to complete the 9/7 DWT for a 512 × 512 image on average, which has high engineering usage. |
