Description
Adds a constant offset to each element of a vector.
pDst[n] = pSrc[n] + offset, 0 <= n < blockSize.
There are separate functions for floating-point, Q7, Q15, and Q31 data types.

- Parameters:
-
[in] | *pSrc | points to the input vector |
[in] | offset | is the offset to be added |
[out] | *pDst | points to the output vector |
[in] | blockSize | number of samples in the vector |

- Parameters:
-
[in] | *pSrc | points to the input vector |
[in] | offset | is the offset to be added |
[out] | *pDst | points to the output vector |
[in] | blockSize | number of samples in the vector |
- Returns:

Scaling and Overflow Behavior:
- The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] are saturated.

- Parameters:
-
[in] | *pSrc | points to the input vector |
[in] | offset | is the offset to be added |
[out] | *pDst | points to the output vector |
[in] | blockSize | number of samples in the vector |
- Returns:
- none.
Scaling and Overflow Behavior:
- The function uses saturating arithmetic. Results outside of the allowable Q31 range [0x80000000 0x7FFFFFFF] are saturated.
