-/**

- * @brief Dot product of Q31 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 1.31 x 1.31 = 2.62 format and these

- * are truncated to 2.48 format by discarding the lower 14 bits.

- * The 2.48 result is then added without saturation to a 64-bit accumulator in 16.48 format.

- * There are 15 guard bits in the accumulator and there is no risk of overflow as long as

- * the length of the vectors is less than 2^16 elements.

- * The return result is in 16.48 format.
