In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. 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 … Pogledajte više 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 … Pogledajte više Named after the French mathematician Évariste Galois, an LFSR in Galois configuration, which is also known as modular, internal XORs, or one-to-many LFSR, is an alternate structure that can generate the same output stream as a conventional … Pogledajte više Binary LFSRs of both Fibonacci and Galois configurations can be expressed as linear functions using matrices in $${\displaystyle \mathbb {F} _{2}}$$ (see GF(2)). Using the companion matrix of the characteristic polynomial of the LFSR and denoting the … Pogledajte više LFSRs can be implemented in hardware, and this makes them useful in applications that require very fast generation of a pseudo-random sequence, such as direct-sequence spread spectrum Pogledajte više As shown by George Marsaglia and further analysed by Richard P. Brent, linear feedback shift registers can be implemented using XOR and Shift operations. This approach lends itself to fast execution in software because these operations … Pogledajte više The following table lists examples of maximal-length feedback polynomials (primitive polynomials) for shift-register lengths up to … Pogledajte više • Ones and zeroes occur in "runs".
