+ * @brief Q15 opt fully-connected layer function
+ * @param[in] pV pointer to input vector
+ * @param[in] pM pointer to matrix weights
+ * @param[in] dim_vec length of the vector
+ * @param[in] num_of_rows number of rows in weight matrix
+ * @param[in] bias_shift amount of left-shift for bias
+ * @param[in] out_shift amount of right-shift for output
+ * @param[in] bias pointer to bias
+ * @param[in,out] pOut pointer to output vector
+ * @param[in,out] vec_buffer pointer to buffer space for input
+ * @return The function returns <code>ARM_MATH_SUCCESS</code>
+ *
+ *
+ * @details
+ *
+ * <b>Buffer size:</b>
+ *
+ * vec_buffer size: 0
+ *
+ * Here we use only one pointer to read 4 rows in the weight
+ * matrix. So if the original matrix looks like this:
+ *
+ * | a11 | a12 | a13 |
+ *
+ * | a21 | a22 | a23 |
+ *
+ * | a31 | a32 | a33 |
+ *
+ * | a41 | a42 | a43 |
+ *
+ * | a51 | a52 | a53 |
+ *
+ * | a61 | a62 | a63 |
+ *
+ * We operates on multiple-of-4 rows, so the first four rows becomes
+ *
+ * | a11 | a12 | a21 | a22 | a31 | a32 | a41 | a42 |
+ *
+ * | a13 | a23 | a33 | a43 |
+ *
+ * Remaining rows are kept the same original order.
+ *
+ * So the stored weight matrix looks like this:
+ *
+ *
+ * | a11 | a12 | a21 | a22 | a31 | a32 | a41 | a42 |
+ *
+ * | a13 | a23 | a33 | a43 | a51 | a52 | a53 | a61 |
+ *
+ * | a62 | a63 |
