However, an LFSR with a well-chosen feedback function can produce a sequence of bits that appears random and has a very long cycle. Likewise, because the register has a finite number of possible states, it must eventually enter a repeating cycle. The initial value of the LFSR is called the seed, and because the operation of the register is deterministic, the stream of values produced by the register is completely determined by its current (or previous) state. In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. Now for something a bit more challenging and mathematical. View the Project on GitHub house-of-abbey/scratch_vhdl Linear Feedback Shift Register (LFSR) The purpose of 'Scratch VHDL' is to make reprogrammable logic design into child's play.
