摘 要: 提出了一种基于FPGA平台和EDA开发工具实现混沌吸引子的方法。针对一个混沌系统,利用理论和数值仿真对系统的基本特性进行了分析.对系统的混沌状态进行了分析。为验证系统的混沌行为,在Matlab的Simulink下,利用DSP Builder设计了一个电路,并转换成VHDL代码程序,用QuartusII下载到FPGA硬件电路中进行了实验,实验结果与仿真结果完全一致。 A method for realizing a chaotic attractor is presented based on the platform of SIMULINK and the EDA tool. Some basic dynamical behaviors of a chaotic are analyzed by using theoretical analysis and numerical simulations. To verify the chaotic behaviors a circuit is designed using the DSP Builder in the environment of Simulink of Matlab. After transforming the circuit file into VHDL code, the VHDL file is downloaded into the FPGA target hardware. The experiment shows a good agreement between the system simulations and the experimental results.
