Reconfigurable logic blocks based on a discrete chaotic circuit : implementation of all fundamental two input, one output logic functions

In this paper, we implement the first realization of a reconfigurable chaotic based logic block that can morph between all two input, one output logic functions. This logic block is constructed based on a discrete time chaotic circuit known as Logistic Map and can directly emulate operation of all two input, one output combinational functions. We have derived instruction set table of this logic block that can be used as a look up table to generate different logic functions. Furthermore, we propose a method to enhance robustness of the constructed logic block with respect to environmental noise. Constructed logic block provides opportunities and possibilities to construct more efficient and higher order reconfigurable logic blocks.
