A General Hardware Implementation Method for Lifting-based DWT

In this paper a general hardware implementation method is proposed for the lifting-based Discrete Wavelet Transform(DWT),which provides the strategy that a designer can take during the DWT implementation according our careful analysis of the finite precision analysis,the architecture design of 1-D and 2-D DWT and also some optimized algorithms and architectures.A case study of a 6/10 DWT is given to show the details of the proposed method.The general method available here can helps to design a high-performance DWT.It can be applied to the hardware design of DWT and the correlative signal processing system design based on DWT.
