Abstract: The paper presents a chaotic system.Some basic dynamical behaviors of the system are further explored by calculating its Lyapunov exponent spectrum and bifurcation diagrams.It is transformed from chaos to quasi-period and period.A digital circuit is designed to the chaotic system by DSP Builder in Simulink of Matalab，the circuit is translated into the VHDL code and downloaded into target hardware.It shows a good agreement between system simulations and experimental results.Furthermore，a method for digital implementation of a continuous chaotic system is proposed by using Field-Programmable Gate Array（FPGA） technology and Electronic Design Automation（EDA） tool.
