The critical path is shown to be the smallest achievable. Synthesis results show that the new scheme can reach a clock rate well exceeding 1 GHz using a 0.13?m technology.}, isbn = {1-58113-853-9}, doi = {http://doi.acm.org/10.1145/988952.989053}, author = {Dadda, Luigi and Macchetti, Marco and Owen, Jeff} }
