Cy_Crypto_Core_MemCpy()

__STATIC_INLINE void Cy_Crypto_Core_MemCpy	(	CRYPTO_Type *	base,
		void *	dst,
		void const *	src,
		uint16_t	size
	)

Function MemCpy uses Crypto HW.

Memory structures should not overlap! There is no alignment restriction. When D-Cache is enabled parameters dst and src must align and end in 32 byte boundary.

Parameters

base	The pointer to the CRYPTO instance.
dst	The pointer to the destination of MemCpy.
src	The pointer to the source of MemCpy.
size	The size in bytes of the copy operation.

Cy_Crypto_Core_MemSet()

__STATIC_INLINE void Cy_Crypto_Core_MemSet	(	CRYPTO_Type *	base,
		void *	dst,
		uint8_t	data,
		uint16_t	size
	)

Function MemSet uses Crypto HW.

There is no alignment restriction. When D-Cache is enabled parameter dst must align and end in 32 byte boundary.

Parameters

base	The pointer to the CRYPTO instance.
dst	The pointer to the destination of MemSet.
data	The value to be set.
size	The size in bytes of the set operation.

Cy_Crypto_Core_MemCmp()

__STATIC_INLINE uint32_t Cy_Crypto_Core_MemCmp	(	CRYPTO_Type *	base,
		void const *	src0,
		void const *	src1,
		uint16_t	size
	)

Function MemCmp uses Crypto HW.

There is no alignment restriction. When D-Cache is enabled parameters src0 and src1 must align and end in 32 byte boundary.

Parameters

base	The pointer to the CRYPTO instance.
src0	The pointer to the first source of MemCmp.
src1	The pointer to the second source of MemCmp.
size	the size in bytes of the compare operation.

Returns

0 - if Source 1 = Source 2, 1 - if not.

Cy_Crypto_Core_MemXor()

__STATIC_INLINE void Cy_Crypto_Core_MemXor	(	CRYPTO_Type *	base,
		void *	dst,
		void const *	src0,
		void const *	src1,
		uint16_t	size
	)

Function MemXor uses Crypto HW.

Memory structures should not overlap! There is no alignment restriction. When D-Cache is enabled parameters dst, src0 and src1 must align and end in 32 byte boundary.

Parameters

base	The pointer to the CRYPTO instance.
dst	The pointer to the destination of MemXor.
src0	The pointer to the first source of MemXor.
src1	The pointer to the second source of MemXor.
size	The size in bytes of the compare operation.

Cy_Crypto_InvertEndianness()

void Cy_Crypto_InvertEndianness	(	void *	inArrPtr,
		uint32_t	byteSize
	)

This function inverts endianness of the byte-array.

Odd or even byteSize are acceptable.

Parameters

inArrPtr	The pointer to the memory whose endianness is to be inverted.
byteSize	The length of the memory array whose endianness is to be inverted (in bytes)
