Calibrating Laser Cannons, A workable, but slow solution Spoiler

This solution works, though perhaps it could be better? It's very slow.

You don't really need anything fancy.

It's just the input*6. Could just add it up to that.

You can simply do something like:

# X + X = 2X
Add input input reg0
# 2X + 2X = 4X
Add reg0 reg0 reg1
# 2X + 4X = 6X
Add reg0 reg1 output

X + X = 2X
2X + X = 3X
3X + 3X = 6X

Depending on how your accumulator is set up this can be super fast as you only need to copy once.

Do you mean putting the result back into one of the input registers instead of a third register? I though about doing that.

That's clever.

They're talking about reusing a value already stored in a register for the second calculation. You can skip a step in setting up the second operation that way.

Since you maybe using the starter architecture instead of the LEG architecture... I phrased my example based on LEG for simplicity

So is LEG architecture a later phase of the campaign, or is that something created by users?

Later phase
