A computing apparatus include a processing circuitry configured to detect a weight depth field, related to a range of a weight value of a plurality of weight values, within the weight value, and detect an activation depth field, related to a range of an activation value of a plurality of activation values, within the activation value; identify a first operand in the weight value, and identify a second operand in the activation value; and generate an output value having a resultant depth field determined based on the weight depth field and the activation depth field, by performing an operation based on the identified first and second operands.
