  • Abstract
    There is an inherent redundancy in multirate algorithms, such as multilevel wavelet analysis, employing conventional FIR filter banks as the computational elements. Here, a novel application of asynchronous control techniques to reduce this redundancy in the VLSI implementation of such algorithms is presented, and an architecture for the Haar discrete wavelet transform is introduced that has improved latency and throughput characteristics, when compared with an equivalent synchronous design
