Abstract
An improved architecture for efficiently calculating a discrete wavelet transform is presented. The present system appreciates the associated redundancies of calculations and proposes a topology for eliminating such redundant calculations through the use of storing and making such previously calculated coefficients available in successive wavelet coefficient calculations. The present system while recognizing redundant calculations and performing storage operations, also provides a pipelined architecture whereby the wavelet coefficients are calculated and combined for use in a wavelet packet tree architecture.
