DARPA UPSIDE: Analog microprocessors could be the unforseen future of computing

DARPA has recently taken a keen interest in the development of a new computer paradigm based on the re-introduction of previously dismissed analog microprocessor technologies. According to DARPA, along with notable academics from UC Berkley and Rice University, the problem with our existing digital processing technologies -- represented by the latest generation of microprocessor chips -- is that we obtain a high degree of precision at an enormous cost in electrical power.  Houston...
