摘要
提出了一种用FPGA技术实现混沌迭代序列的一种新方法,该方法适用于符合二次三项式牲征的混沌系统。根据离散化和数字化处理技术,对三维混沌系统作离散化处理,同时对实数进行处理,使离散化后的混沌系统和实数处理后的数据便于在FPGA中实现。利用VHDL硬件描述语言编程和FPGA技术产生三维混沌迭代序列。本文以chen系统为例,阐述这种方法的设计流程。基于芯片型号为EP2C35F672C6的FPGA开发平台,给出FPGA硬件实现的结果,并在显波器上显示产生的混沌吸引子。
this article puts forward a new method that realizes chaotic iteration sequence with FPGA technology, This method applys to the chaotic systems that accord with character of twice and trinomial. According to discrete and digital process technology,threedimensional chaotic System is l.discretized and at the same time handled for real number,which makes chaotic system and the data realize easily.in FPGA .Using VHDL. hardware description language and FPGA technology,Chaotic iteration sequence is generated.This article is taking chen system as example, elaborate the design process of this kind of method. On the basis of FPGA exploitation platform with EP2C35F672C6 chip, FPGA hardware implementation result is given and showed on the oscillograph.
