ABSTRACT:
In one embodiment, a scale and bias unit for use in a graphics system includes a preclamping unit configured to receive an input and to responsively generate an output value equal to a first value if the input is within a first input range. The scale and bias unit also includes a processing unit coupled to the preclamping unit and configured to perform a calculation on the input to generate the output value. The processing unit does not perform the calculation if the input is within the first input range.
