This paper examines the design of a hybrid prefix adder under the condition of non-uniform input signal arrival. This is encountered in the final adder for fast parallel multipliers, which use column compression reduction. The prefix graph scheme efficiently accommodates the non-uniform arrival times. Rules are presented for designing hybrid prefix adders under such conditions. This rule produces adders which are faster and less complex than previous work.
