- * @param[in]       *pSrcB points to the second input vector
- * @param[out]      *pDst points to the output vector
- * @param[in]       blockSize number of samples in each vector
- * @return none.

- * <b>Scaling and Overflow Behavior:</b>

- * The function uses saturating arithmetic.
- * Results outside of the allowable Q31 range [0x80000000 0x7FFFFFFF] will be saturated.
