基于FPGA的数字混沌序列的实现及性能分析
Implementation and Performance Analysis of Digital Chaotic Sequence Based on FPGA
摘要
Abstract
In order to achieve digital chaotic PN sequence, a digital technology for continuous system is proposed based on FPGA platform. For a chaotic system, the system's basic characteristics are analyzed by theory and numerical simulation. The state transition of the system is analyzed by Lyapunov exponent spectrum and bifurcation diagrams. A circuit is designed by DSPBuilder in Simulink of Matlab, and the circuit is translated into the VHDL code and downloaded into FPGA target hardware by Quartus Ⅱ , the digital chaotic PN sequence is observed in the experiment. In addition, perfermance of the sequences is measured by NIST test. The result shows that the perfermance of sequences is good.关键词
