The model is parameterizable in terms of input bit-widths and can be applied to a wide variety of datapath components. The good trade-off between estimation accuracy, model complexity and flexibility makes the model attractive for power analysis and optimization tasks on a high level of abstraction. Furthermore, a new approach is presented, that allows to calculate the average Hamming-distance distribution of an input data stream. It will be demon-strated, that the application of Hamming-distance distri-butions, instead of only average values, improves the estimation accuracy for a number of typical DSP-modules and data streams.} @COMMENTBibtex file generated on
