Abstract

It is shown how any combinational function that can be described by a flow table or equivalently is realizable in iterative form can be realized in tree form. The propagation delay is then proportional to the logarithm of n, the number of inputs, while the logic complexity is a linear function of n. These results are related to various implementations of high-speed binary adders and a proposed new high-speed adder circuit.
