Abstract :
This paper shows how to implement the wavelet transform and the Fast Fourier Transform (FFT) with a Field Programmed Gate Array (FPGA). First, it introduces the implementation of the wavelet transform with lattice filters and achieves the FFT with the Coordinate Rotational Digital Computation (CORDIC). Then, the emulation data of the Daubechies D4 & D6 wavelet transforms and the FFT with 16 points are given, and their performances are analyzed. The results prove this to be a novel and effective method to implement the wavelet transform and the FFT with FPGA
