- * @brief Multiplies a Q15 vector by a scalar.
- * @param[in]       *pSrc points to the input vector
- * @param[in]       scaleFract fractional portion of the scale value
- * @param[in]       shift number of bits to shift the result by
- * @param[out]      *pDst points to the output vector
- * @param[in]       blockSize number of samples in the vector
- * @return none.
- *
- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The input data <code>*pSrc</code> and <code>scaleFract</code> are in 1.15 format.
- * These are multiplied to yield a 2.30 intermediate result and this is shifted with saturation to 1.15 format.
