Abstract

Abstract

In recent years, the wavelet transform has been widely used in many fields. The fast tower-type algorithm is an efficient tool. Its importance is just like that of FFT in the Fourier analysis. Therefore the hardware implementation of the DWT is an important problem in its applications. With the introduction of the parallel systolic FIR filter structure to the design of the wavelet decomposition filter, an implementation structure of wavelet decomposition filter is presented in this paper. As being parallel and systolic, the structure can increase data throughput and reduce power consumption of the system as well as enhance operation speed.
