+ *
+ * Q7_Q15 version of the fully connected layer
+ *
+ * Weights are in q7_t and Activations are in q15_t
+ *
+ * Limitation: x4 version requires weight reordering to work
+ *
+ * Here we use only one pointer to read 4 rows in the weight
+ * matrix. So if the original q7_t matrix looks like this:
+ *
+ * | a11 | a12 | a13 | a14 | a15 | a16 | a17 |
+ *
+ * | a21 | a22 | a23 | a24 | a25 | a26 | a27 |
+ *
+ * | a31 | a32 | a33 | a34 | a35 | a36 | a37 |
+ *
+ * | a41 | a42 | a43 | a44 | a45 | a46 | a47 |
+ *
+ * | a51 | a52 | a53 | a54 | a55 | a56 | a57 |
+ *
+ * | a61 | a62 | a63 | a64 | a65 | a66 | a67 |
+ *
+ * We operates on multiple-of-4 rows, so the first four rows becomes
+ *
+ * | a11 | a21 | a12 | a22 | a31 | a41 | a32 | a42 |
+ *
+ * | a13 | a23 | a14 | a24 | a33 | a43 | a34 | a44 |
+ *
+ * | a15 | a25 | a16 | a26 | a35 | a45 | a36 | a46 |
+ *
+ * The column left over will be in-order.
+ * which is:
+ * | a17 | a27 | a37 | a47 |
+ *
+ * For the left-over rows, we do 1x1 computation, so the data remains
+ * as its original order.
+ *
+ * So the stored weight matrix looks like this:
+ *
+ * | a11 | a21 | a12 | a22 | a31 | a41 |
+ *
+ * | a32 | a42 | a13 | a23 | a14 | a24 |
+ *
+ * | a33 | a43 | a34 | a44 | a15 | a25 |
+ *
+ * | a16 | a26 | a35 | a45 | a36 | a46 |
+ *
+ * | a17 | a27 | a37 | a47 | a51 | a52 |
+ *
+ * | a53 | a54 | a55 | a56 | a57 | a61 |
+ *
+ * | a62 | a63 | a64 | a65 | a66 | a67 |

+ * @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

+ * @return The function returns <code>ARM_MATH_SUCCESS</code>
+ *
+ * @details
+ *
+ * <b>Buffer size:</b>
+ *
+ * vec_buffer size: dim_vec
+ *
+ * This opt function is designed to work with interleaved weight
+ * matrix. The vector input is assumed in q7_t format, we call
+ * arm_q7_to_q15_no_shift_shuffle function to expand into
+ * q15_t format with certain weight re-ordering, refer to the function
+ * comments for more details.
+ * Here we use only one pointer to read 4 rows in the weight
+ * matrix. So if the original q7_t matrix looks like this:
+ *
+ * | a11 | a12 | a13 | a14 | a15 | a16 | a17 |
+ *
+ * | a21 | a22 | a23 | a24 | a25 | a26 | a27 |
+ *
+ * | a31 | a32 | a33 | a34 | a35 | a36 | a37 |
+ *
+ * | a41 | a42 | a43 | a44 | a45 | a46 | a47 |
+ *
+ * | a51 | a52 | a53 | a54 | a55 | a56 | a57 |
+ *
+ * | a61 | a62 | a63 | a64 | a65 | a66 | a67 |
+ *
+ *
+ * We operates on multiple-of-4 rows, so the first four rows becomes
+ *
+ * | a11 | a21 | a13 | a23 | a31 | a41 | a33 | a43 |
+ *
+ * | a12 | a22 | a14 | a24 | a32 | a42 | a34 | a44 |
+ *
+ * | a15 | a25 | a35 | a45 | a16 | a26 | a36 | a46 |
+ *
+ * So within the kernel, we first read the re-ordered vector in as:
+ *
+ * | b1 | b3 | and | b2 | b4 |
+ *
+ * the four q31_t weights will look like
+ *
+ * | a11 | a13 |, | a21 | a23 |, | a31 | a33 |, | a41 | a43 |
+ *
+ * | a12 | a14 |, | a22 | a24 |, | a32 | a34 |, | a42 | a44 |
+ *
+ * The column left over will be in-order.
+ * which is:
+ *
+ * | a17 | a27 | a37 | a47 |
+ *
+ * For the left-over rows, we do 1x1 computation, so the data remains
+ * as its original order.
+ *
+ * So the stored weight matrix looks like this:
+ *
+ * | a11 | a21 | a13 | a23 | a31 | a41 |
+ *
+ * | a33 | a43 | a12 | a22 | a14 | a24 |
+ *
+ * | a32 | a42 | a34 | a44 | a15 | a25 |
+ *
+ * | a35 | a45 | a16 | a26 | a36 | a46 |
+ *
+ * | a17 | a27 | a37 | a47 | a51 | a52 |
+ *
+ * | a53 | a54 | a55 | a56 | a57 | a61 |
+ *
+ * | a62 | a63 | a64 | a65 | a66 | a67 |
+ *
