Abstract
The presentation will provide an introduction to Intel Labs University Collaborative Research. This will be followed by a review of advanced power management techniques that have been employed in leading designs. Aggressive technology scaling has enabled very high transistor integration capacity. Complex functions are integrated into hardware with multiple heterogeneous cores and caches. Managing total power consumption has emerged as the most challenging task in today’s highly complex microprocessor systems. Independent per-core dynamic voltage scaling is proven to be an effective way to minimize power consumption. It needs multiple voltage rails supplied by independent voltage regulators. Traditionally, the regulators are based on the system platform and utilize large discrete passive components. Due to the size and routing planes, the number of independent platform rails is limited to a very small number. Integrated voltage regulators provide a practical solution. They operate at a high switching frequency, employ small passive components and hence provide large number of ultra-fast independent voltages. This presentation includes a survey of recent research in integrated voltage regulators at Intel.
