An ARM-FPGA-based Co-Design for Implementing Chaotic Systems

An ARM-FPGA-based interface for implementing nonlinear systems through project-based learning for undergraduate students is presented in this work. This setup has a low cost and can be utilized in courses (post-graduate and under-graduate) related to dynamical systems to show the complex behaviors such as chaos, bi-stability, hidden attractors, etc. It consists of a Python-based program in the ARM processor to control the implementation on the FPGA board. As examples, the physical implementation of Lorenz system, as well as the realization of a hidden chaotic system are given.
