摘要
在现代工程实践中,伪随机序列广泛应用于信息安全、数字通信、密码学、自动控制等领域中。本文设计了一种基于TD-ERCS混沌系统和混沌序列均匀化普适算法的伪随机序列发生器;采用32位高性能浮点型数字信号处理芯片实现了IEEE754双精度浮点型标准的PRSG;DSPs与PC的通讯采用了USB2.0传输协议。依据美国国家标准与技术研究院所提出的伪随机序列性能指标,对迭代所产生的混沌伪随机序列进行了测试,结果表明该PRSG所产生的CPRS性能良好,为算法的硬件实现做了很好的前期验证。
In modern engineering practice,the pseudo-random sequence（PRS） has been widely applied in many fields such as information security,digital communications,cryptography,automation.In this dissertation,a method of designing pseudo-Random sequence generator（PRSG） based on tangent-delay ellipse reflecting cavity map system（TD-ERCS） and the universal algorithm transforming chaotic sequence into uniform pseudo-random sequenc is designed.The PRSG by using high performance 32-bit floating-point digital signal processors（DSPs） realized which conform to the IEEE754 double-precision floating-point standard.By employing USB2.0 transfer protocol in the communication between pc and DSPs.According to the criterion of PRS published by National institute of standards and technology（NIST）,test results show that the PRSG achieve the expected effect.It has done a very good pre-authentication for the hardware implement of chaos PRSG.
