基于线性反馈移位寄存器（LFSR）的伪随机数生成器的文档，对于由n个寄存器组成的LFSR，可生成2^n - 1个不重复的序列。
以下是基本介绍：
Shift registers longer than eight bits can be implemented most efficiently in XC4000E Select-RAMTM. Using Linear Feedback
Shift-Register (LFSR) counters to address the RAM makes the design even simpler. This application note describes 4- and
5-bit universal LFSR counters, very efficient RAM-based 32-bit and 100-bit shift registers, and pseudo-random sequence
generators with repetition rates of thousands and even trillions of years, useful for testing and encryption purposes. The
appropriate taps for maximum-length LFSR counters of up to 168 bits are listed.
