This chapter describes the process of mapping the image compression algorithm SPIHT onto a reconfigurable logic architecture. A discussion of why adaptive logic is required, as opposed to an ASIC, is provided, along with background material on SPIHT. Several discrete wavelet transform hardware architectures are analyzed and evaluated. In addition, two major modifications to the original image compression algorithm, which are required in order to build a reconfigurable hardware implementation, are presented: (1) the storage elements necessary for each wavelet coefficient, and (2) a modification to ...
