Detailed Description

Element-by-element addition of two vectors.

    aOutData[n] = aInDataA[n] + aInDataB[n],   0 <= n < aCount.
  

There are separate functions for floating-point, Q7, Q15, and Q31 data types.

		const f32_t *__restrict	aInDataA,
		const f32_t *__restrict	aInDataB,
		uint32_t	aCount )

Floating-point vector addition.

Parameters

[out]	aOutData	points to output vector
[in]	aInDataA	points to first input vector

Scaling and Overflow Behavior

The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] are saturated.

tpt_add_q31()

void tpt_add_q31	(	q31_t *__restrict	aOutData,
		const q31_t *__restrict	aInDataA,
		const q31_t *__restrict	aInDataB,
		uint32_t	aCount )

Q31 vector addition.

Parameters

[out]	aOutData	points to output vector
[in]	aInDataA	points to first input vector
[in]	aInDataB	points to second input vector
[in]	aCount	number of samples in each vector

Returns

none

Scaling and Overflow Behavior

The function uses saturating arithmetic. Results outside of the allowable Q31 range [0x80000000 0x7FFFFFFF] are saturated.

tpt_add_q7()

void tpt_add_q7	(	q7_t *__restrict	aOutData,
		const q7_t *__restrict	aInDataA,
		const q7_t *__restrict	aInDataB,
		uint32_t	aCount )

Q7 vector addition.

Parameters

[out]	aOutData	points to output vector
[in]	aInDataA	points to first input vector
[in]	aInDataB	points to second input vector
