+ *
+ * The computation kernel arm_nn_mat_mult_kernel_q7_q15_reordered does the

+ * @param[in] dim_im_in_y input tensor dimention y

+ * @param[in] padding_x padding sizes x
+ * @param[in] padding_y padding sizes y
+ * @param[in] stride_x convolution stride x
+ * @param[in] stride_y convolution stride y
+ * @param[in] bias pointer to bias
+ * @param[in] bias_shift amount of left-shift for bias
+ * @param[in] out_shift amount of right-shift for output
+ * @param[in,out] Im_out pointer to output tensor
+ * @param[in] dim_im_out_x output tensor dimension x
+ * @param[in] dim_im_out_y output tensor dimension y
+ * @param[in,out] bufferA pointer to buffer space for input
+ * @param[in,out] bufferB pointer to buffer space for output
+ * @return The function returns either
+ * <code>ARM_MATH_SIZE_MISMATCH</code> or <code>ARM_MATH_SUCCESS</code> based on the outcome of size checking.
+ *
+ * This function is the version with full list of optimization tricks, but with
+ * some contraints:
+ * ch_im_in is multiple of 2
+ * ch_im_out is multiple of 2

+ * @return The function returns <code>ARM_MATH_SUCCESS</code>
+ *
+ * @details
+ *
+ * <b>Buffer size:</b>
+ *
+ * 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 |
+ *
+ * | a31 | a32 | a33 |

+ * | 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:

+ * <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 |
+ *

+ * @brief tables for various activation functions
+ *
+ * This file include the declaration of common tables.
+ * Most of them are used for activation functions
+ *
+ * Assumption:
+ * Unified table: input is 3.x format, i.e, range of [-8, 8)
+ * sigmoid(8) = 0.9996646498695336
+ * tanh(8) = 0.9999997749296758
+ * The accuracy here should be good enough
+ *
+ * 2-stage HL table:
+ *
+ * The entire input range is divided into two parts:
+ *
+ * Low range table: 0x000x xxxx or 0x111x xxxx
+ * table entry will be the binary number excluding the first
+ * two digits, i.e., 0x0x xxxx or 0x1x xxxx
+ *
+ *
+ *
+ * High range table 0x0010 0000 -- 0x0111 1111
+ * 0x1000 0000 -- 0x1101 1111
+ *
+ * For positive numbers, table entry will be
+ * 0x0010 0000 -- 0x0111 1111 minus 0x0010 0000
+ * i.e., 0x0000 0000 - 0x0101 11111
+ *
+ * same thing for the negative numbers, table entry will be
+ * 0x1000 0000 -- 0x1101 1111 minux 0x0010 0000
+ * i.e., 0x0110 0000 - 0x1011 1111

+ * The relative output will be different here.
