Technology challenges and opportunities for ubiquitous computing

Unprecedented transistor integration capacity will be available to make computing truly ubiquitous, but the energy consumption will be a major challenge. Compute energy can be reduced by employing near threshold voltage operation. However, data movement energy will become prohibitive. Software will have to be cognizant of data locality, with introspection for fine grain energy management. The entire stack has to participate in implementing resiliency. Such a holistic system approach will make computing truly ubiquitous.
