  139. <p>Perform fully-connected layer</p>
    140. 

  140. <p>Fully-connected layer is basically a matrix-vector multiplication with bias. The matrix is the weights and the input/output vectors are the activation values. Supported {weight, activation} precisions include {8-bit, 8-bit}, {16-bit, 16-bit}, and {8-bit, 16-bit}.</p>
    141. 

  141. <p>Here we have two types of kernel functions. The basic function implements the function using regular GEMV approach. The opt functions operates with weights in interleaved formats. </p>

  707. <p>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:</p>
    708. 

  708. <p>| a11 | a12 | a13 | a14 | a15 | a16 | a17 |</p>
    709. 

  709. <p>| a21 | a22 | a23 | a24 | a25 | a26 | a27 |</p>
    710. 

  710. <p>| a31 | a32 | a33 | a34 | a35 | a36 | a37 |</p>
    711. 

  711. <p>| a41 | a42 | a43 | a44 | a45 | a46 | a47 |</p>
    712. 

  712. <p>| a51 | a52 | a53 | a54 | a55 | a56 | a57 |</p>
    713. 

  713. <p>| a61 | a62 | a63 | a64 | a65 | a66 | a67 |</p>
    714. 

  714. <p>We operates on multiple-of-4 rows, so the first four rows becomes</p>
    715. 

  715. <p>| a11 | a21 | a13 | a23 | a31 | a41 | a33 | a43 |</p>
    716. 

  716. <p>| a12 | a22 | a14 | a24 | a32 | a42 | a34 | a44 |</p>
    717. 

  717. <p>| a15 | a25 | a35 | a45 | a16 | a26 | a36 | a46 |</p>
    718. 

  718. <p>So within the kernel, we first read the re-ordered vector in as:</p>
    719. 

  719. <p>| b1 | b3 | and | b2 | b4 |</p>
    720. 

  720. <p>the four q31_t weights will look like</p>
    721. 

  721. <p>| a11 | a13 |, | a21 | a23 |, | a31 | a33 |, | a41 | a43 |</p>
    722. 

  722. <p>| a12 | a14 |, | a22 | a24 |, | a32 | a34 |, | a42 | a44 |</p>
    723. 

  723. <p>The column left over will be in-order. which is:</p>
    724. 

  724. <p>| a17 | a27 | a37 | a47 |</p>
    725. 

  725. <p>For the left-over rows, we do 1x1 computation, so the data remains as its original order.</p>
    726. 

  726. <p>So the stored weight matrix looks like this:</p>
    727. 

  727. <p>| a11 | a21 | a13 | a23 | a31 | a41 |</p>
    728.

    729. 

  729. <p>| a32 | a42 | a34 | a44 | a15 | a25 |</p>
    730. 

  730. <p>| a35 | a45 | a16 | a26 | a36 | a46 |</p>
    731. 

  731. <p>| a17 | a27 | a37 | a47 | a51 | a52 |</p>
    732. 

  732. <p>| a53 | a54 | a55 | a56 | a57 | a61 |</p>
