Mission of Power Management Not Accomplished at All



Power consumption is increasingly an important design constraint in both software and hardware across the boards in computer systems. For mobile devices, the resulting battery life is the top purchase driver to the buyers. This talk introduces Intel’s leading silicon technology in mass production and its advancements in performance per watt in recent generations. On top of that, the talk reviews the long road for system power management to achieve energy efficiency, and then shares the thoughts looking into where we are going and the key challenges and opportunities ahead.
