| 摘 要： | 提出了一种基于FPGA新的实现超混沌系统的方法,利用Matlab／Simulink 中的DSP Builder工具箱设计了一个电路模型,仿真成功后,把模型文件转换成VHDL代码程序,对VHDL语言代码进行编译、仿真、配置后,用Quartus II下载到FPGA硬件电路中.结果表明新方法简单方便且能有效地产生超混沌吸引子.实验结果与仿真结果完全一致.

| Abstract: | A novel method was adopted to design a hyperchaotic system Generator,based on a hyperchaotic system and implemented in FPGA.This method was based on the Matlab/Simulink,Altera Quartus II and DSP Builder.The hyperchaotic system was built by Altera DSP Builder,which is embedded into the Matlab/Simulink as a toolbox.After successful simulation of this model,the VHDL code was generated automatically.Then this code could be complied,simulated,configured and download by the Altera Quartus II.The research results indicated that this new method is not only simple and convenient but also effective to precisely produce a hyperchaotic system.It showed good agreement between system simulations and experimental results. |
