【Abstract】 The wavelet transform(WT) has been extensively applied to signal processing systems.Special purpose hardware is needed to implement the huge computation of WT.The VLSI implementation of continuous wavelet has not only conspicuous superiority in speed,power consumption,and the frequence range applied,but flexible ways of implementation.But it has been scarcely explored.This paper tries to summarize the research on this field,and the problems associated are also discussed.Finally,several directions in the development of the VLSI implementation of CWT are pointed out.更多还原
