摘　　要：以多涡卷Jerk系统为例,介绍了利用DSP处理器实现连续混沌系统的方法。同时设计了相应的模拟硬件电路,并分别给出了硬件实验结果。实验结果表明,利用DSP产生的实验结果与模拟电路产生的结果完全一致,证实了该方法的可行性。该方法同样可以实现其他连续混沌系统,具有普适性。该方法还存在着调试方便,参数调节灵活,计算误差可控性强,频谱调节范围较宽且方便等优点,便于实现数字保密通信。An effective approach for generating continual-chaotic system by using the Digital Signal Processor（DSP） is presented in this paper. Taking the Jerk system as an example, we introduced how to implement using the DSP device, and designed analog hardware circuit. Then, the experimental results of analog and digital are given respectively at the same time. The two results are in good agreement. This confirms the feasibility of our method. A number of experiments show that this method can also be applied to other continual systems. It is convenient, flexible and easy to use in digital secure communication.
