Based on the fifth-order hyperchaotic circuit system and the digital processing technology, the chaotic attractors in hyperchaotic circuit system equations using FPGA technology is implemented physically through discretizing the continuous-time state equation and variable scaling. The FPGA technology for realizing chaotic attractors is given and physical implementation method is put forward. The experimental results are showed in this paper. It provides a practical method for design and realization of the high-order chaotic circuit systems. At the same time, the technology can be applied in chaotic encryption communication.
