- * @brief Negates the elements of a Q15 vector.
- * @param[in] *pSrc points to the input vector
- * @param[out] *pDst points to the output vector
- * @param[in] blockSize number of samples in the vector
- * @return none.
- *
- * \par Conditions for optimum performance
- * Input and output buffers should be aligned by 32-bit
- *
- *
- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The function uses saturating arithmetic.
- * The Q15 value -1 (0x8000) will be saturated to the maximum allowable positive value 0x7FFF.
