+ * @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.
