Abstract

Because of the increasing demand of low power digitalsystems, it is of great interest to extend the existing high-levelpower estimation techniques to handle flexible datamodels, as they appear in relevant applications. This paperpresents a data model and an algorithm suitable for estimatingthe transition activity in linear digital signal processingarchitectures. The technique extends previous proposedapproaches to handle a generalized class of correlatedand non-necessary Gaussian data distributions. Usingthe derived models, an estimation technique is proposedand evaluated for practical examples. Bit level simulationsresults show the adequate accuracy of the proposed approach.
