摘要:In this paper, we present a new efficient distributed arithmetic (NEDA) formulation of the computation of 1-Ddiscrete wavelet transform (DWT) using 9/7 filters, and mapped that into bit parallel for high-speed and low hardwareimplementations, respectively. We demonstrate that NEDA is a very efficient architecture with adders as the maincomponent and free of ROM, multiplication, and subtraction. The bit-parallel structure has 100% hardware utilizationefficiency. Compared with the existing multiplier-less structures, the proposed structures offer significantly higherthroughput rate and involve less area-delay product
