Abstract :
A pipelined carry look-ahead adder is described which is particularly suitable for use with a pipelined parallel multiplier, but would also be useful for other pipelined systems. The adder is compared with a pipelined ripple-carry adder having a triangular structure and the nonpipelined form of the carry look-ahead adder and is shown to possess the advantages of small stage delay and short flush time.
