Abstract:
A device for performing at least one saturation operation, the device comprising:a saturation control signal generation circuit for generating first and second saturation control signals as a function of a data value input to said control signal generation circuit, the saturation control signals being of a first or second state, said saturation control signal generation circuit including means for logically ANDing a highest order bit included in said data value with an additional value generated from at least one other bit included in said data value to generate one of said first and second saturation control signals; and a controllable switching device including a data value input for receiving a data value, a first saturation threshold input for receiving a first saturation threshold value and a second saturation threshold input for receiving a second saturation threshold value, the switching device being responsive to the state of the first and second saturation control signals to output a selected one of the data value, first saturation threshold value, and second saturation threshold.
