Hardware Design of a Kind of Grid Multi-Scroll Chaotic System Based on a MSP430F169 Chip

摘要

Based on only MSP430F169 chip, a digital chaotic generator for a grid-like JERK chaotic system is designed, from which grid-like 6 x 6 chaotic attractors are generated. By analyzing the nonlinear functions of the gird-like chaotic system, the saddle focal balance points are respectively extended in x,y direction. According to the hardware requirements of MSP430F169 chip, using Euler algorithm to discretize the chaotic system, the values of 36 saddle focal balance points need to be recalculated. The numerical values of the focal balance points which are involving iterative operations are given by the proposed comparative piece-wise method, their analysis and numerical simulations are also performed. The software and hardware design ideas are given for implementation, the experiment results are verification of the feasibility of the scheme.
