Macro Definition Documentation

◆ CRC_POL_DEFAULT

#define CRC_POL_DEFAULT 0x04C11DB7

Default polynomial.

Definition at line 90 of file crc_v2.h.

Function Documentation

◆ crc_calculate()

uint32_t crc_calculate ( uint32_t data )

Writes a data word to the register, the write operation stalling until the computation is complete.

Parameters

[in] data new word to add to the CRC calculator

Returns: int32 Computed CRC result

Definition at line 36 of file crc_common_all.c.

References CRC_DR.

◆ crc_calculate_block()

uint32_t crc_calculate_block	(	uint32_t *	datap,
		int	size
	)

Add a block of data to the CRC calculator and return the final result.

Writes data words consecutively to the register, the write operation stalling until the computation of each word is complete, then returns the final result

Parameters

[in]	datap	pointer to an array of 32 bit data words.
[in]	size	length of data, in 32bit increments

Returns: final CRC calculator value
