The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift … Se mer The bit positions that affect the next state are called the taps. In the diagram the taps are [16,14,13,11]. The rightmost bit of the LFSR is called the output bit. The taps are XOR'd sequentially with the output bit and then fed back into the … Se mer Named after the French mathematician Évariste Galois, an LFSR in Galois configuration, which is also known as modular, internal … Se mer Binary LFSRs of both Fibonacci and Galois configurations can be expressed as linear functions using matrices in $${\displaystyle \mathbb {F} _{2}}$$ (see GF(2)).
