It is widely acknowledged that the exponentially improving benefits of sustained technology scaling prophesied by the Moore's Law would end within the next decade or so, attributed primarily to an understanding that switching devices can no longer function deterministically as feature sizes are scaled down to the molecular levels. The benefits of Moore's Law could, however, continue provided systems with probabilistic or “error-prone” elements could still process information usefully. We believe that this is indeed possible in contexts where the “quality” of the results of the computation is perceptually determined by our senses—audio and video information being significant examples. To demonstrate this principle, we will show how such “inexact” computing based devices, circuits and computing architectures can be used effectively to realize many ubiquitous energy-constrained error-resilient applications.
