Reconfigurable chaotic logic gates based on novel chaotic circuit

•A novel method for implementing logic gates based on chaotic maps is introduced.•The logic gates can be implemented without any changes in the threshold voltage.•The chaos-based logic gates may serve as basic components of future computing devices.

The logical operations are one of the key issues in today’s computer architecture. Nowadays, there is a great interest in developing alternative ways to get the logic operations by chaos computing. In this paper, a novel implementation method of reconfigurable logic gates based on one-parameter families of chaotic maps is introduced. The special behavior of these chaotic maps can be utilized to provide same threshold voltage for all logic gates. However, there is a wide interval for choosing a control parameter for all reconfigurable logic gates. Furthermore, an experimental implementation of this nonlinear system is presented to demonstrate the robustness of computing capability of chaotic circuits.
