Function Documentation

tpt_dot_prod_u8()

uint32_t tpt_dot_prod_u8	(	uint8_t *	aInDataA,
		uint8_t *	aInDataB,
		uint32_t	aCount
	)

Dot production of U8 vectors.

Parameters

aInDataA	Points to the U8 format input vector.
aInDataB	Points to the U8 format input vector.
aCount	Size of the vectors.

Returns

uint32_t dot product of two input vectors.

The output of multiplications is in 0.16 format and then added to an accumulator in 16.16 format. The return result is in 16.16 format.When the size of the vectors less than (2^15)-1, there is no risk to overflow.
