- * @brief Mean value of a Q7 vector.
- * @param[in]       *pSrc points to the input vector
- * @param[in]       blockSize length of the input vector
- * @param[out]      *pResult mean value returned here

- *
- * @details
- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The function is implemented using a 32-bit internal accumulator.
- * The input is represented in 1.7 format and is accumulated in a 32-bit
- * accumulator in 25.7 format.
- * There is no risk of internal overflow with this approach, and the
- * full precision of intermediate result is preserved.
- * Finally, the accumulator is truncated to yield a result of 1.7 format.
