[LAD] entailments of probabilistic processing chip for DSP and audio processing?

http://www.technologyreview.com/read_article.aspx?id=26055&a=f A computer chip that performs calculations using probabilities, instead of binary logic, could accelerate everything from online banking systems to the flash memory in smart phones and other gadgets. [...] The electrical signals inside Lyric's chips represent probabilities, instead of 1s and 0s. While the transistors of conventional chips are arranged into components called digital NAND gates, which can be used to implement all possible digital logic functions, those in a probability processor make building blocks known as Bayesian NAND gates. Bayesian probability is a field of mathematics named after the eighteenth century English statistician Thomas Bayes, who developed the early ideas on which it is based. [...] Lyric has been working on its technology in stealth mode since 2006, partly with funding from the U.S. Defense Advanced Research Projects Agency. DARPA is interested in potential defense applications that would involve working with information that isn't clear cut--for example, radio signals distorted accidentally or otherwise, and machine vision systems that try to recognize actions or objects in images. "They're interested in some James Bond-type applications," says Vigoda. Niels http://nielsmayer.com
