- * @brief Converts the elements of the floating-point vector to Q15 vector.
- * @param[in] *pSrc points to the floating-point input vector
- * @param[out] *pDst points to the Q15 output vector
- * @param[in] blockSize length of the input vector
- * @return none.
- *
- * \par Description:
- * \par
- * The equation used for the conversion process is:
- * <pre>
- * pDst[n] = (q15_t)(pSrc[n] * 32768); 0 <= n < blockSize.
- * </pre>
- * \par Scaling and Overflow Behavior:
- * \par
- * The function uses saturating arithmetic.
- * Results outside of the allowable Q15 range [0x8000 0x7FFF] will be saturated.
- * \note
- * In order to apply rounding, the library should be rebuilt with the ROUNDING macro
- * defined in the preprocessor section of project options.
