SESSION 24
RESEARCH PAPER SESSION: Relax and Save: Trading Off Accuracy for Energy
Chair:
Umit Y. Ogras - Arizona State Univ., Tempe, AZ
Many applications exhibit inherent tolerance to computational errors. Relaxing the constraints on exact computation opens up huge opportunities for improving energy efficiency without excessively sacrificing quality. The papers in this session present solutions and methodologies for exploiting approximate computing in a variety of ways, such as the use imprecise hardware, near-threshold operations, and the use of fault-tolerant caches.
