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

- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The intermediate multiplications are in 1.7 x 1.7 = 2.14 format and these
- * results are added to an accumulator in 18.14 format.
- * Nonsaturating additions are used and there is no danger of wrap around as long as
- * the vectors are less than 2^18 elements long.
- * The return result is in 18.14 format.
