Abstract :
A cost-effective VLSI architecture with separate data-paths and their corresponding filter structure is proposed for performing a two-dimensional discrete wavelet transform (2D DWT). Compared with the conventional 2D DWT VLSI architectures, the proposed semi-recursive 2D DWT VLSI architecture has minimum hardware cost, and optimised data-bus utilisation, scheduling control overhead and storage size
