Abstract

The emergence of dark silicon - a fundamental design constraint absent in the past generations - brings intriguing challenges and opportunities in microprocessor design. To gracefully embrace dark silicon, design methodologies must adapt themselves to identify progressive systems that can effectively exploit the growing dark silicon. We demonstrate that relying on traditional design metrics may lead to sub-optimal design choices with the rise of the dark silicon area. We provide a new metric to guide a dark silicon aware system design and propose a stochastic optimization algorithm for dark silicon aware multicore system design. Our design approach shows 7-23% benefit in upcoming technology generations. © 2012 ACM.
