Verilog数字系统基础设计-LFSR
LFSR(线性反馈移位寄存器）用于产生可重复的伪随机序列PRBS，该电路由n级触发器和一些异或门组成。在每个时钟周期内，新的输入值会被反馈到LFSR内部各个触发器的输入端，输人值中的一部分来源于LFSR的输出端，另一部分由LFSR各输出端进行异或运算得到。

Verilog数字系统基础设计-扰码与解扰
发送电路在发送数据前先对数据进行随机扰乱，接收电路使用相同的扰乱算法重新恢复出原始的数据。 什么是扰码与解扰 扰码器使用LFSR实现，用来产生伪随机比特序列，它和串行输入的数据进行异或，从而实现对输入数据的随机化。正如我们在LFSR部分讨论过的 ...

Linear Feedback Shift Registers For FPGAs
One way to generate seemingly random sequences is to use a linear feedback shift register or LFSR. You can use LFSRs in software, but they are also very useful in hardware design and [Adam Taylor ...

Tutorial: Linear Feedback Shift Registers (LFSRs) – Part 1
The equivalent to the Ouroboros in the world of electronics would be the Linear Feedback Shift Register (LFSR), in which the output from a standard shift register is cunningly manipulated and fed back ...

LFSR provides encryption
For example, the cryptographic algorithms in the GSM (Global System for Mobile communications) mobile-phone system rely on the use of LFSRs. An LFSR comprises a register containing a sequence of bits ...
