摘要 以Lorenz混沌方程为例,提出了利用FPGA技术实现混沌序列模型的一种方法。对数字积分器、量化电路进行设计,采用DSP Builder工具形成Lorenz混沌输出序列,并在FPGA实验开发系统上进行了下载,最后使用Agilent公司的1693A逻辑分析仪对实验箱输出的序列进行了观察,详细地讲述了这一系列的过程。该设计方法根据系统需要和资源利用率可适当提高运算精度,并可应用于其他连续混沌系统中,有助于加快混沌系统在信息安全及保密通信领域中的应用。 This paper takes Lorenz chaos equation as an example to put forward a way to achieve chaos output sequence modal by FPGA technology. Based on the design of digital integrator and quantification circuit, we get Lorenz chaotic output sequence hy DSP Builder tool and download it on the FPGA experiment system. Finally, the output sequence is observed by 1693A logic analyzer from Agilent Company. The whole process is described here in detail, This method of design may improve arithmetic precision according to the needs of the system and resource using ratio and can be used in other continuous chaotic system and the application of chaotic system in information security and secure communication field will be accelerated.
