FPGA Implementation of X- and Heart-shapes Controllable Multi-Scroll Attractors
This paper proposes new multi-scrolls chaotic systems which is called the X-shape. The purpose is to have more complex systems and flexible ranges of the chaotic behavior. The proposed X-shape is a combination between V-shape and Λ-shape. This paper also represents the Heart-shape which considered a special case of the X-shape. The system complexity has been measured by MLE and compared with V-shape system. It shows lager MLE on the side of X-shape. In addition, the effect of changing system parameters has been discussed and compared with V-shape. Finally, a fully hardware implantation on FPGA has been proposed using Nexys 4 Artix-7 FPGA XC7A100T with optimum resources and the experimental results are provided. © 2018 IEEE.
