Abstract

This work presents a novel configurable architecture for 1-dimensional discrete wavelet transform (DWT) which can be configured into different types of filters with different lengths. The architecture adopts polyphase filter structure and MAC loop based filter (MLBF) to achieve high computing performance and strong generality of the system. Loop unrolling approach is used to eliminate the data hazards caused by pipelining. The hardware usage of the configurable architecture is fixed for any kind of wavelet functions.
