MaxPeriodGaloisLFSR

class MaxPeriodGaloisLFSR extends GaloisLFSR

A maximal period Galois Linear Feedback Shift Register (LFSR) generator. The maximal period taps are sourced from LFSR.tapsMaxPeriod.

Instance Constructors

  1. new MaxPeriodGaloisLFSR(width: Int, seed: Option[BigInt] = Some(1), reduction: LFSRReduce = XOR)

    width

    the width of the LFSR

    seed

    an initial value for internal LFSR state. If None, then the LFSR state LSB will be set to a known safe value on reset (to prevent lock up).

    reduction

    the reduction operation (either XOR or XNOR)
