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.
