- * @brief Q31 vector absolute value.

- * @param[in]       *pSrc points to the input buffer

- * @param[out]      *pDst points to the output buffer

- * @param[in]       blockSize number of samples in each vector

- * @return none.

- *

- * <b>Scaling and Overflow Behavior:</b>

- * \par

- * The function uses saturating arithmetic.

- * The Q31 value -1 (0x80000000) will be saturated to the maximum allowable positive value 0x7FFFFFFF.
