- * @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
- * @return none.

- * @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.
