Lorenz chaotic model using Filed Programmable Gate Array (FPGA)

In this paper, we introduce a new method to implement chaotic generators based on Lorenz chaotic system given by the state equations by using Filed Programmable Gate Array (FPGA). The aim of this method is to increase the frequency of the chaotic signals. The new method is based on MATLAB^® Software, Xilinx System Generator, Xilinx Alliance tools, Leonardo spectrum or Synplicity Synplify and ModelSim XE PLUSE. The toolbox of the Xilinx System Generator used as toolbox under MATLAB^® Simulink toolbox to convert any MATLAB^® Simulink model to the Xilinx System Generator model then to generate the VHDL code for that model. The hardware can be used directly in chaotic communication systems with high frequency.
