RE: Instant Comperator Carry adder - minestyler007 - 07-09-2016

hmm i didnt experience that it would be one additional tick...
i still dont get CCA i think I'll have to learn it at some point.

anyways there are some new cool things i found out. you dont have to sync the inputs because the bug will also work if the inputs came before the back input as it has to calculate the first side input in 1 tick and then will give the output which will make the other comparators become their side inputs one tick later so it will still calculate everything without delay.

i also found out that you can expand it infinitly - as long as the back inputs are still synced. I'm not too sure about it as i tried it in my singleplayer world which is 1.8.
I don't have internet often so i can't test it on the server

So i finally managed to make a kind of good adder... it is 8 ticks and has a useless doubleinversion that i didn't get rid off because i was super annoyed by this shit because it took me about 15 tries to make it work but all  in all I'm quite happy with how it worked. the carry line never dies out but you have to power the back inputs of the comparator line all at once.

I also found a new way for the carry propagation. it would not need the back inputs to be powered by a cpu anymore nut still need synced inputs AND at least 1 tick of all zero between every calculation.

It works as follows: AND for generate and XOR for propagate. the xor will be connected to the back inputs of the carry - line comparators. so the comparators would only have there back inputs activated if they could propagate.

i found out that it works if it propagates but it ripples if it DOESN'T propagate. but i think you could get rid of this.

also it can be 4 ticks if someone is able to make a 1 tick xor that you can stack 2 wide (actually it's 2 wide and diagonal but a kind of horizonatl diagonal...)

seriously ? F3 F1 THEN F2 is really this hard to press ??????????

Anyway this thing is interesting

sorry realized that thats annyoing too but too late...

RE: Instant Comperator Carry adder - minestyler007 - 07-20-2016

i built another adder which is 7 ticks and uses the new way for carrying

some things i found:
  • works best if the comparators face south (north is ok 2 but had this ripple thing for the very last comparator).
  • the back inputs have to be powered with redstone dust that is full signal strength and that is powered by redstone torches
  • if you power it in a different way you have to have every second comparator have less signal strength then the one before which leads to signal strength loss of 2 power per bit.

uh, good luck solving the directional issue, i had started to map out the working directions of some 1 tick circuits, but there is more to consider than we realize, like chunk position, even when its fully within the chunk i've had 2 identical circuits behave differently. but this is still neat, it reminds me of a hybrid between analog and binary.

RE: Instant Comperator Carry adder - Apocryphan - 08-25-2016

here are some of my notes when i was attempting to decipher the directional issue. inputs with red wool do not work and ones with green do. these are all 1 tick pulsers if you ever need one, try these.

And here is something that may help when timing 2 signals to meet.

Josh at least unlike your bumps his are productive...

thats because all of my bumps were in shenanigans (except for that ONE TIME where i didnt know bumping was a thing and i only had forums account for like a week or two
