摘要
小波变换是当代信号处理技术常用的数学方法之一,它在视频压缩方面也有很好的前景。根据Daubechies等人于1996年提出的整型小波变换方法,用FPGA设计并实现了4层整数(5,3)小波变换,硬件实现结果与软件实现结果基本一致.
Wavelet transform is one of the important methods for signal processing in recent years. It is widely used in video compression. This (5,3) wavelet transform is to adapt the arithmetic of daubechies et al. Four layers (5,3) integer lifting is implemented by FPGA. The results of FPGA correspond with software emulators.
