Design Method for Duffing System Based on DSP Builder

DSP Builder is a design tool in algorithms level, which makes the algorithms realized on FPGA rapid and convenient. In this paper, by the related research on Duffing system, a digital circuit based on DSP Builder is proposed, which solves the problem that the chaotic system of analog circuit system is vulnerable to external conditions. In order to realize the digital circuit based on DSP Builder, an improved Euler algorithm is proposed. Then the circuit can be translated into the VHDL code and downloaded into FPGA.
