Abstract
A high performance adder is provided including a predicted carry look ahead coupled between a lower order adder and a higher order adder of the high performance adder. The predicted carry look ahead provides as an input to the carry input of the adder a prediction of a carry bit produced by the adding of lower order bits of two addends by the lower order adder. By this arrangement, the highest order adder can operate on the highest order bits of two addends with a predicted carry and without having to wait for the results of the carries that occur in the lower order bits.
