Harnessing error-prone chips

30 octubre 2014

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. In many popular applications — video rendering, for instance — users probably wouldn’t notice the difference, and it could significantly improve energy efficiency.
