Efficient VLSI suited architectures for discrete wavelet transforms
Sandra Simon, P. Rieder, Josef A. Nossek · 2002
A variety of architectures for the discrete wavelet transform (DWT) is examined to derive an efficient VLSI implementation. The comparison leads to a lattice filter structure which uses single steps of the CORDIC algorithm. Due to the modular structure of the proposed architecture, this approach is especially suited for full custom design style using module generators to automate the manual design process.
