Abstract :
A highly area-efficient multiplier-less filterbank architecture for one-and two-dimensional discrete wavelet transforms (DWT) is presented. The look-up table (LUT) structure in traditional distributed arithmetic (DA)-based filter structures has been dissolved to implement a LUT-less DA-DWT with dual filterbanks, which permits the reuse of the same circuitry for both highpass and lowpass filters.
