In this paper we review the architectures designed for wavelet transi:brms, with the purpose to highlight their suitability for inclusion in codec systems. Indeed, common VLSI cost functions (such as AT ~-) are insufficient to evaluate architectures for compression. At the system level, quantization and coding have processing requirements that must be taken into account when designing the transform engine. The hierarchical structure of wavelet transform allows to use "pyramid" algorithms that

Such approaches can be substituted with more standard ones, if data reordering is mandatory to apply a good quantization strategy. An upcoming commercial solution offers a sound comparison paradigm.
