|Single Effective Gate: Distributive Computation in Noisy Environments|
|Keywords: Extreme Cold, Reliability, Computation|
|The purpose of this project is to demonstrate the use of an ensemble of logic gates to achieve reliable computation in an extremely noisy environment. Special regard is given to high temperature and radiation effects that result in spatial and temporal noise. In the case of an example logic gate, where electric noise results in the failure of the function, multiple gates can be averaged in order to estimate the true logical result (within a certain reliability). This basic concept is demonstrated using a novel and simple bistable circuit and a reconfigurable framework for adaptively recruiting gates into the ensemble. Theoretical results indicate that optimal coupling between the elements within the ensemble can result in an optimal operation of the logic function. In addition, the 'path' of computation via the ensemble of nonlinear and coupled elements, will degrade smoothly with regard to increased noise and increased time related errors. Theoretical and experimental results are used to demonstrate the practicality of these concepts.|
