1. A wavelet transformation circuit comprising: a set of data inputs; a bank of shift registers, for loading a succession of pixel value from a digital image, each successive pixel value being loaded at a preselected clock interval; a set of coefficient registers that correspond to said bank of shift registers, for storing coefficient values implementing a wavelet filter; a multiplier/accumulator circuit that generates, at said preselected clock interval, a result based on application of said coefficient values against the succession of pixel values stored by said bank of shift registers; and at least one result register for storing said result.
