Design optimizations of a high performance microprocessor using combinations of dual-V/sub T/ allocation and transistor sizing

Joint optimizations of dual-V/sub T/ allocation and transistor sizing reduce low-V/sub T/ usage by 36%-45% and leakage power by 20% in a high performance microprocessor, with minimal impact on total active power and die area. An enhancement of the optimum design allows processor frequency to be increased efficiently during manufacturing.
