Abstract:
In this paper,the chaotic Lorenz system is carried out through FPGA technology,which can decrease the deviation from the expected effect. Firstly,the differential equation is decomposed in discretized equation,and then the circuit model by DSP-Builder software platform is obtained,which can be translated directly into the VHDL language. Secondly,Lorenz system is tested through the program in hardware description languages,i.e.Verilog HDL. By analyzing the simulation results of the above two methods,the advantages and disadvantages are summarized,respectively. These results provides a reference method to achieve the research in nonlinear system by using FPGA.
