Description
This function provides a table driven 32bit CRC generation for
byte data. This CRC is known as the CCITT CRC32.
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
This function provides a table driven 16bit CRC generation for
byte data. This CRC is calculated with the POLYNOME 0x8005
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
This function provides a table driven 16bit CRC generation for
byte data. This CRC is known as the HDLC CRC.
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
This function provides a table driven 16bit CRC generation for
byte data. This CRC is known as the CCITT CRC16
(POLYNOME = 0x1021).
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
Bit Reverse Array: array which allows to reverse one octet.
Frequently used in mathematical algorithms.
Used for example in the CRC16 calculation.
