Abstract:Low memory requirement and reduced latency have been two major concerns in the implementation of the 2D Daubechies discrete wavelet transform. In this study, a multilevel 2D Daubechies-4 (Daub-4) wavelet filter architecture based on an algebraic integer (AI) is investigated. This architecture can improve the traditional Daub-4 very large scale integration (VLSI) architecture design and reduce the number of adders in a 1D Daub-4 filter module architecture. The is because the AI-based multilevel architecture doe… Show more
