A study of VLSI architectures for 2-D Discrete Wavelet Transform

In this paper we presented the different VLSI architectures for the computation of 2-D Discrete Wavelet Transform (DWT). These Architectures are based on Recursive Pyramid Algorithm (RPA), Systolic Array architecture and Parallel Filter architecture. A comparative analysis, on the basis of computational complexity and hardware utilization, of these architectures is presented here.
