- *
- * NEGEMMLowpQuantizeDownInt32ToUint8ScaleByFixedPoint depends on 3 parameters:
- *
- * result_fixedpoint_multiplier, result_shift, result_offset_after_shift
- *
- * The final result is:
- *
- * (FixedPointMul(input[i][k], result_fixedpoint_multiplier) >> result_shift) + result_offset_after_shift
- *
- * where FixedPointMul(x, y) is the nearest integer to the following
- * mathematical expression, evaluated without overflow or intermediate rounding:
- *
- * (x * y) / 2^31
- *
- * For more information: https://github.com/google/gemmlowp/blob/master/public/output_stages.h#L68
- *
- * In case the bias tensor is provided, the final result is:
- *
- * ((FixedPointMul(input[i][k] + bias[k], result_fixedpoint_multiplier)) >> result_shift) + result_offset_after_shift
- *
- * This function calls the following kernels:
- *
- * -# @ref NEGEMMLowpQuantizeDownInt32ToUint8ScaleByFixedPointKernel
- *
- * @note The function accepts also 2 optional input arguments (min and max) which can be used to implement "rectified linear unit" activation functions
- * after the result is shifted right by result_shift
