  ASimpleCreator: id:2061643 Showcases a nice example of single-row computation.

  ASimpleCreator: There's also a plethora of YouTube videos on the topic, some better than others. Just look up "koggestone addition" or "carry-lookahead addition".

  ASimpleCreator: Koggestone is usefull for us subframers because it has the potential to be more compact due to the reduction in steps. I see you're in the subframe discord, so I recommend taking your time and reading through that website that was recently posted there on koggestone addition. If you have any more questions after, don't be afraid to come back here.

  ASimpleCreator: Koggestone is a clever adaptation of the conventional ripple-carry adder, which in the real world makes adders faster by avoiding the "ripple-carry" in most cases. Normally, when a ripple-carry adder needs to carry a bit to the next module, it does this sequentially, thus creating a ripple effect that travels through the adder. Koggestone adders or "carry-lookahead adders" can predict a carry based on the initial inputs, thus reducing delay.

  ASimpleCreator: You can also prevent contamination of your result due to DTEC affecting FILT, which it's not supposed to, by using the tmp=6 (no effect) FILT mode.

  ASimpleCreator: Okay, since your most recent save showcases an adder, we'll start there. Right now, there's a row in between every calculation that's empty. You could try reducing that by setting up a sparker array. That's when you have two solid sparks copied down multiple times using DRAY. These are placed diagonal of each other, creating a zigzag pattern.

  also could you maybe try explaining koggestone to me l o l

  im already familiar with subframe & filt, but can you give me some extra knowledge on some techniques i might not know, that would come in handy for making smaller and smaller designs since thats practically one of the main goals of filt

  Zero5556: The computer itself, though, is finished apart from the conditional flags and jump handling. That shouldn't take much more time.
