I need a 2 wide tileable 4 tall half adder design for the binary multiplier that I'm building. I've spent a lot of time trying to figure one out, but none of my designs so far have fit. If anybody could give me a hand, I'd really appreciate it.
Here is the multipler in question:
I could try to come up with a design, but you would to show the outputs/inputs a bit more clearly; I'm absolutely sure I could make a half adder with the dimensions you need though.

Here, would this help? These are the outputs. They're color coded based on the power of two that they represent, from left to right. There's one block in between each column of outputs and there's one block between each row (this is where the redstone dust is).
Sorry for taking so long to respond, but I think what you're looking for is a 2 x 4 x n full adder. I don't really understand how you want to use a half adder for your setup. Half adders have two inputs, and if linked together (with carries) they effectively only have one input per bit. Full adders however, have three, and if linked together, they will effectively have two.
It's a little weird, but basically, say you have 4 bits (1, 2, 4, 8). Linking them with half adders will only allow you to add one to the the 4 bits. With full adders, you could add one, AND add another 4 bits.

So is this what you want?
yeah, honestly I'm not sure what I was thinking when I said half adder. I think I meant full adder, but I could have just been being really stupid. thanks
Well I tried, but it doesn't look good. Making one 1-wide/4-high tillable XOR gate for the adder was REALLY hard, although I did eventually get it. By that point the thing was already 14 blocks long, and I honestly cannot imagine trying to shove another similar XOR gate, (along with logic for the carry).
So as much as I think anybody would want a multiplier that is that compact, I'm afraid that it would be too slow and inefficient; maybe it's impossible.

well, thanks for your help. it is a bummer, I couldn't come up with any designs that worked either. oh well. :/
