<div class="textblock"><p>NEON kernel used to quantize down the int32 accumulator values of GEMMLowp to QASYMM8. </p>
<p>This kernel takes a final int32 accumulator value (the output of <a class="el" href="classarm__compute_1_1_n_e_g_e_m_m_lowp_matrix_multiply_kernel.xhtml">NEGEMMLowpMatrixMultiplyKernel</a>), and processes it to obtain the final QASYMM8 value. The following computations will be performed by the kernel:</p>
<ol type="1">
<li>Add offset terms to final result</li>
<li>Multiply each entry of result by result_mult_int</li>
<li>Add bias to final result if bias tensor is not a nullptr</li>
<li>Shift the int32 accumulator by result_shift</li>
<li>Clamp the value between the specified min and max bounds</li>
<li>Clamp the resulting int32 values to the [0..255] range and cast to QASYMM8. </li>
</ol>
