Abstract
PowerTune is a power-management technique for a multi-gigahertz superscalar 64b PowerPC® processor in a 90nm technology. This paper discusses the challenges and implementation of a dynamically controlled clock frequency with noise suppression as well as a synchronization circuit for a multi-processor system.
