- *
- * vec_buffer size: 0
- *
- * 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 |

- * Here we use only one pointer to read 4 rows in the weight

- *
- * | a11 | a12 | a13 |
- *
- * | a21 | a22 | a23 |
- *

- * | 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 |

- * @brief Q7 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: 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 |
- *
