基于fpga产生的伪随机数，很好的学习资料，值得学习-Fpga generate pseudo-random numbers, good learning materials, it is worth learning

随机数的产生算法介绍：任意分布的伪随机变量的抽样，方法包括直接抽样方法，变换抽样法，舍选抽样法等。-Random number generation algorithm: the arbitrarily distributed pseudo-random variable sampling methods including direct sampling method, transform sampling method- rejection sampling method.

1.线性同余随机数生成器介绍： 古老的LCG(linear congruential generator)代表了最好最朴素的伪随机数产生器算法。主要原因是容易理解，容易实现，而且速度快。 -A linear congruential random number generator: ancient LCG (linear congruential generator) represents the best and most simple pseudo-random number ge

用伪链表实现约瑟夫环，其中的密码用的不是随机数，可以自行设置。-Joseph ring with pseudo list, the password is not used random number, you can set up their own.
