摘　　要：对典型的一维Logistic混沌系统和三阶JERK混沌系统进行分析,在MSP430F169一块芯片上采用简单的欧拉法将混沌系统离散化,用浮点、定点两种编程方法实现混沌信号的输出。为实现混沌系统与芯片电路的统一,给出了芯片设计的比例扩张迭代过程和硬件实现的结果,并比较了两种设计方法的优缺点及应用。The typical one-dimensional Logistic chaotic system and three-dimensional JERK chaotic system are analysed. Chaotic digital signals are output by floating and fixing program designs in the MSP430F169 chip using simple Euler method to discretize chaotic system. In order to integrate chaotic system and the chip, the iterative process of Logistic and JERK proportional expansion equations and hardware results are given, and advantages and applications of the two design methods are compared.
