Function Documentation

tpt_dot_prod_u8xq15()

q31_t tpt_dot_prod_u8xq15	(	uint8_t *	aInDataA,
		q15_t *	aInDataB,
		uint32_t	aCount
	)

Dot production of U8xQ15 vectors.

Parameters

aInDataA	Points to the U8 format input vector.
aInDataB	Points to the Q15 format input vector.
aCount	Size of the vectors.

Returns

q31_t dot product of two input vectors.

The output of multiplications is in 1.23 format and then added to an accumulator in 9.23 format. The return result is in 9.23 format.When the size of the vectors less than (2^8)-1, there is no risk to overflow.
