Abstract :
Energy-efficient design requires exploration of available algorithms, recurrence structures, energy and wire tradeoffs, circuit design techniques, circuit sizing and system constraints. In this paper, methodology for energy-efficient design applied to 64-bit adders implemented with static CMOS, dynamic CMOS and CMOS compound domino logic families, is presented. We also examined 65 nm, 45 nm, 32 nm, and 22 nm technology nodes to explore the applicability of the results in deep submicron technologies. By applying energy-delay tradeoffs on various levels, we developed adder topology yielding up to 20% performance improvement and 4.5× energy reduction over existing designs.
