A Reconfigurable Architecture for Discrete and Continuous Wavelet Transforms
Shen Hai-bin · 2005
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.
