Description
Element-by-element multiplication 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.

- 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.

[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.
