- * This kernel takes a final int32 accumulator value (the output of @ref CLGEMMLowpMatrixMultiplyKernel), and processes it to obtain the final QASYMM8 value.
- * The following computations will be performed by the kernel:
- *
- *  -# Compute fixed point multiplication between each entry of input by result_fixedpoint_multiplier
- *  -# Add bias to final result if bias tensor is not a nullptr
- *  -# Requantize
- *  -# Add offset to each result
- *  -# Clamp the value between the specified min and max bounds
- *  -# Clamp the resulting int32 values to the [0..255] range and cast to QASYMM8.
