ez-lfsr

lfsr.py is a small Python utility for generating maximal-length (m-sequence) Galois LFSR output sequences and Gold codes. Output can be emitted as comma-separated bits or as a packed hexadecimal value.

Usage

Repository contents

• lfsr.py Command-line tool that generates:

  • LFSR sequences from [#bits] [taps] [init]
  • Gold codes from --gold/-g [codeindex] [#bits] [taps1] [taps2] [init]

• lfsr_feedback_terms/ Precomputed feedback tap terms (by register width) useful for selecting maximal-length polynomials.

• galois_lfsr_in_c/ Minimal C reference implementation / demo of the same Galois LFSR stepping logic.
