In this paper, we propose a novel, efficient VLSI architecture for the implementation of one-dimension, lifting-based discrete wavelet transform (DWT). Both of the folded and the pipelined schemes are applied in the proposed architecture; the former scheme supports higher hardware utilization and the latter scheme speed up the clock rate of the DWT. The architecture has been coded in Verilog HDL, then verified successfully by the platform of Quartus-II of version 5.0. Finally, it was realized with the FPGA device of Cyclone family from Altera Corp.
