By re-using a single full adder multiple times, a relatively simple circuit can process very large numbers over multiple cycles.

    @szymciu If you represent negative number differently (via bit magic), it work with negatives.

    Yes, with subframe tech like in id:2003533, one can perform 3 8-bit additions per frame ("60 Hz") with a circuit that takes up less space than the serial adder in id:1703470. I haven't made a compact subframe serial adder yet.

    Too bad it only works on positive numbers, though.

    I say compared to some 0 delay subframe adder that are pretty small and fast

    its not supposed to be fast, just to do big numbers without taking up the entire screen. The full adder in the centre has a processing time of 6 frames, which isn't a very long time. It just also gets run every 8 frames, 27 times.
