- * @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.
