Back propagation neural network and chaos dynamics are combined in this paper. The global-optimum and dynamic-adjusting neural network is trained by the chaos series from non-linear system so as to approach the mapping feature of that system. So

a chaos generation scheme based on the neural network is proposed. By using nonlinear neural network with learning ability

this scheme doesn't have to be designed to be a single system structure for a certain nonlinear chaotic map. At last

using DSP technology

a Chaos Neural Network Co-processer Flashboard is made based on the CGNN. The chaos is used as a encrypeted key in the encryption telecommunication.
