- * @brief Dot product of Q7 vectors.

- * @param[in]       *pSrcA points to the first input vector

- * @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.
