In this paper, we describe an efficient Xilinx Virtix4 discrete wavelet transform (DWT) using 9/7 filter based new efficient distributed arithmetic (NEDA) Technique.We demonstrate that NEDA is a very efficient architecture with adders as the main component and free of ROM, multiplication, and subtraction.This technique supports any size of image pixel value and any level of decomposition.The bit-parallel structure has 100% hardware utilization efficiency.Compared with the existing multiplier-less structures, the proposed structures offer significantly higher throughput rate and involve less area-delay product.
