Abstract
An analytical performance evaluation model is presented in this paper. A time-splitting transmitter circuit employing a selectively activated flip-driver (SAFD) is presented and its performance is estimated by the new model. The optimal partitioning method which maximizes the performance of a given bus-invert (BI) coding circuit is also presented. When a bus is optimally partitioned, an ordinary BI circuit can reduce the number of bus transitions by about 25%, while an SAFD circuit can remove about 35% of them. The newly developed method is verified by simulations whose results correspond very well to the values predicted by the model.
