Abstract: Based on the classical Chua’s chaotic circuit, a 5-Dimentional and dual flux-controlled memristive chaotic circuit system is designed. The nonlinear characteristics of the circuit are analyzed numerically and the results show that the circuit has rich chaotic dynamical behavior. The novel memristive continuous system is transformed into digital system by first-order discrete processing. Based on DSP Builder and FPGA technology, a hardware platform of Cyclone Ⅳ E series EP4CE10F17C8N chip realizes the digital system of the model. The design results indicate that the digital memristive system avoids the drift and instability of analog components, the display performance of the hardware waveform is stable and reliable, and is consistent with the computer simulation result.
