| 摘 要： | 针对现有的PRNG的均匀性差的特性,文献1]提出了一种将混沌序列变换成均匀伪随机序列的普适算法。我们首次提出该算法的FPGA实现方案,方案由上位机软件、UART控制器、初值缓存器、均匀化算法实现单元、尾数序列缓存转换器组成。采用VHDL完成各模块设计,芯片选用逻辑资源为100万门的CycloneIIEP2C35F672C6,硬件电路共占6721逻辑单元,资源率20%,工作频率为50MHz。

| Abstract: | Aiming at the poor uniformity of existing PRNG,literature1] presents a universal algorithm for transforming chaotic sequences of either chaotic map systems or chaotic differentrial dynamic systems into uniform pseudo-random sequences.We present a scheme for FPGA implementation of the algorithm at the first time.This scheme consist of upper computer software,UART Controller,initial value buffer,uniformization algorithm implementation unit and mantissa sequence transformer.Using CycloneII EP2C35F672C6 chip w... |
