摘要
对高质量随机数的要求与日俱增,导致了真随机数发生器受到广泛关注;系统芯片技术的出现和发展,提出了实现片上随机数发生器的需要;鉴于这两个现实状况,该文提出了一种基于锁相环噪声源的随机数发生器实现方法。实验结果表明该方法具有真随机性,易于实现和系统集成。
The requirement of high quality random numbers grows day by day, so true random number generator takes great attentions; And the appearance and development of system on a chip needs the realization of on-chip random number generator. Considering the two facts, this paper comes up with a new method of random number generator based on the noise source of PLL.The method can provide a good property: true randomness and easy realization and system integration.
