A low power VLSI implementation of reconjgumble complex Continuous Wavelet Transform (CWT) algorithm to generate the two dimensional time scale representation of a one dimensional signal is introduced The CWT is computationalEy intensive process. The CWT processor presented in this paper employs a bank of cornlators. The correlators which are not needed in a certain transform are disabled to save power. So power consumption ofthe CWT pmcessor depend on the number of scales. The processor has been implemented and ynthesized using ALCATEL 0.35~ technology. Matlab, RTL> and netlist simulation results venjf, that the implemented algorithm has the potential to be utilized as a wavelet coprocessor for fast time-scale analysis in real-time.
