This study presents a dual-edge triggered static scanable flip-flop suitable for low-power applications. The proposed circuit deploys reduced swing-clock and swing-data to manage dynamic power. Furthermore, it employs clock- and power-gating during idle mode to eliminate dynamic power and reduce static power, while retaining its state. The static structure of the circuit makes it feasible to be used...
Using exact switching activity rates at all internal nodes when calculating energy of digital circuits is believed to result in improved accuracy over to the use of average switching activity.We compare the two approaches in the case of the Kogge-Stone adder implemented with Weinberger and Ling addition recurrences. The difference between the two is less than 4%.Further we examined the accuracy of...
Total energy consumption of a micro-architecture directly depends on the switching factors of the internal nodes. Weinberger and Ling are the most widely used binary addition algorithms that are used in microprocessor adders. In this paper, the switching activity behaviors of those well known addition recurrence structures are explored. The formulae for estimation of switching activity rates of signals...
