<div class="textblock"><p>NEON kernel used to add the offset contribution after <a class="el" href="classarm__compute_1_1_n_e_g_e_m_m_lowp_matrix_multiply_kernel.xhtml">NEGEMMLowpMatrixMultiplyKernel</a>. </p>
<p>The computation is performed in-place</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 adds to it the offset contribution of matrix A and matrix B in-place.</p>
<p>The final result is:</p>
<p>mm_result[i][k] = mm_result[i][k] + (vector_sum_col[k] * a_offset) + (vector_sum_row[i] * b_offset) + (a_offset * b_offset * k) </p>
