摘要：in this paper, we present a VLSI architecture for the separable two-dimensional Discrete Wavelet Transform (DWT) decomposition. Using a recursive property, we showed how the proposed separable architecture uses only a minimal number of filters to generate all level of DWT computation. For the computation of an N x N 2-D DWT with a filter length L, the architecture requires 2(L-1) adders, 2L multipliers, (2L+1) multiplexers and a RAM of size (N/2 x N/2). The hardware utilization of architecture is 100%
