Wire crossing with no crossing wires

[killing_you_guy_]

I recently made a device that crosses two wires without either one ever going over the other.It works with 3 XOR gates, and is as flat as possible for this kind of thing. Working on speeding it up and comparatorizing it to make it small, fast, and stackable. Now it's time to get to work on that pancake computer!

I imagine it is setup like this with comparator XORs or something.

Sort of, but now I'm having trouble squeezing it into a reasonable space. I'm lining up the xors and sending the other lines around the sides. It works like the. Algorithm for searching variables without a third variable, where you do a=a XOR b; b=b XOR a; a=a XOR b;. If I can make more improvements, I may make a flat alu or even computer.

I couldn't upload pics because the forum wasn't letting me.

Finally got a screenshot of the crossing, and i got it down to 4 ticks!
hoping for 3 eventually, but its pretty good for now.

After some minor signal strength issues, I've managed to create a decently-sized 2 tick version of this using 1 tick comparator xors. This is a very interesting concept, and 2 ticks is almost fast enough to be useful in certain situations. (although it would have to be designed to be 2 wide tileable).



Repeaters are for synchronization.

While I love the over-exemplification of logic, one cannot beat simple raising one wire and lowering another.

Edit: And proper already has a solution to this.
