RECONFIGURABLE AND RELIABLE LOGIC CIRCUIT ELEMENTS THAT EXPLOIT NONLINEARITY AND NOISE

摘要

A logic gate is adapted to implement logical expressions. The logic gate includes at least one input that is adapted to receive an input signal and at least one control signal. At least one of the input signal and the control signal is a noise signal. At least one output is adapted to produce an output signal. A nonlinear updater operates as a dynamically configurable element and produces multiple different logic gates as selected by the control signal based at least in part on the noise signal. The nonlinear updater is electrically coupled to the input and is also electrically coupled to the output. The nonlinear updates is configured to apply a nonlinear function to the input signal in response to the control signal to produce the output signal representing a logical expression being implemented by one of the multiple different logic gates on the input signal.
