pylab_ml.common.data.crc4

crc4(data)

Calculate 4-bit crc from a data with width bits.

polynomial = X4+X+1

eg. crc4(0b1011) -> 0b1110

crc4(0b1101) -> 0b0110 crc4(0b1111) -> 0b0000

Parameters:

data (int) – Input data for which the CRC is to be calculated. The data should be a non-negative integer.

Returns:

The calculated 4-bit CRC value as an integer.

Return type:

int
