Function Documentation

__STATIC_INLINE cy_en_crypto_status_t Cy_Crypto_Core_Prng_Init	(	CRYPTO_Type *	base,
		uint32_t	lfsr32InitState,
		uint32_t	lfsr31InitState,
		uint32_t	lfsr29InitState
	)

Initializes the PRND parameters.

Invoking this function causes a restart of the pseudo-random sequence.

Parameters

base	The pointer to the CRYPTO instance.
lfsr32InitState	A non-zero seed value for the first LFSR.
lfsr31InitState	A non-zero seed value for the second LFSR.
lfsr29InitState	A non-zero seed value for the third LFSR.

__STATIC_INLINE cy_en_crypto_status_t Cy_Crypto_Core_Prng	(	CRYPTO_Type *	base,
		uint32_t	max,
		uint32_t *	randomNum
	)

Generates a Pseudo Random Number.

Parameters

base	The pointer to the CRYPTO instance.
max	The maximum value of a random number.
randomNum	The pointer to a variable to store the generated pseudo random number.

__STATIC_INLINE cy_en_crypto_status_t Cy_Crypto_Core_Trng	(	CRYPTO_Type *	base,
		uint32_t	GAROPol,
		uint32_t	FIROPol,
		uint32_t	max,
		uint32_t *	randomNum
	)

Generates a True Random Number.

Parameters

base	The pointer to the CRYPTO instance.
GAROPol	The polynomial for the programmable Galois ring oscillator.
FIROPol	The polynomial for the programmable Fibonacci ring oscillator.
max	The maximum length of a random number, in the range of [0, 32] bits.
randomNum	The pointer to a generated true random number. Must be 4-byte aligned.
