Abstract
Lookahead carry circuitry is provided for use with the consecutive bit stages of a digital adder whereby the computational throughput of an arithmetic logic unit can be increased (in other words reduced in time of operation). This is accomplished by reducing the number of gates required in the serial switching path to minimize the time delay for generation of carry output signals.
