Abstract:
Methods and apparatus provide for a carry generation tree for a carry look-ahead binary adder, which includes N stages of operators, reducers, and/or repeaters, wherein: a first of the stages receives binary outputs from a series of binary adders; a last of the stages produces a carry out signal representing the carry state of the series of binary adders; and any operator in a given stage does not receive signals from more than one operator in a preceding stage.
