Detailed Description
Element-by-element addition of two vectors.
pDst[n] = pSrcA[n] + pSrcB[n], 0 <= n < blockSize.
There are separate functions for floating-point, Q7, Q15, and Q31 data types.

void arm_add_f32 | ( | float32_t * | pSrcA, |
float32_t * | pSrcB, | ||
float32_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Floating-point vector addition.
- Parameters:
-
[in] *pSrcA points to the first input vector [in] *pSrcB points to the second input vector [out] *pDst points to the output vector [in] blockSize number of samples in each vector
- Returns:
- none.

void arm_add_q15 | ( | q15_t * | pSrcA, |
q15_t * | pSrcB, | ||
q15_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Q15 vector addition.
- Parameters:
-
[in] *pSrcA points to the first input vector [in] *pSrcB points to the second input vector [out] *pDst points to the output vector [in] blockSize number of samples in each vector
- Returns:
- none.
Scaling and Overflow Behavior:
- The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] will be saturated.

q31_t * | pSrcB, | ||
q31_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Q31 vector addition.
- Parameters:
-
[in] *pSrcA points to the first input vector [in] *pSrcB points to the second input vector [out] *pDst points to the output vector [in] blockSize 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] will be saturated.
