- * @param[in]       *pSrcA        pointer to the first input vector
- * @param[in]       *pSrcB        pointer to the second input vector
- * @param[out]      *pDst         pointer to the output vector
- * @param[in]       out_shift     amount of right-shift for output
- * @param[in]       blockSize     number of samples in each vector
- * @return none.
- *
- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The function uses saturating arithmetic.
- * Results outside of the allowable Q15 range [0x8000 0x7FFF] will be saturated.
