Introduction of threshold-crc4

Model Details of threshold-crc4

threshold-crc4

CRC-4 generator using polynomial x^4 + x + 1 (CRC-4-ITU).

Function

crc4(d3, d2, d1, d0) -> (crc3, crc2, crc1, crc0)

Computes 4-bit CRC for 4-bit input data.

Polynomial

G(x) = x^4 + x + 1 = 10011 (binary)

This is the ITU-T standard CRC-4 polynomial.

Parallel CRC Equations

For 4-bit input, the CRC bits are:

  • crc0 = d3 XOR d0
  • crc1 = d2 XOR d1 XOR d0
  • crc2 = d3 XOR d1
  • crc3 = d3 XOR d2

Architecture

Each CRC bit is computed using XOR gates:
