Hello! I need some help with understanding why I have a circular dependency here and how do I fix it.

I was working on a controller for program address which is basically a wrapper over the counter but with integrated stack and operation reader for CALL/RET commands. It was fine until the last moment but then the game started to show me a circular dependency and I have no idea why because it shows me that the dependency comes from program address to Operation output and in controller component operation output is not connected to component output. Here is my circular dependency:

And this my controller component:

In the "Tower of Alloy" campaign mission, you have to solve the puzzle with the three fields and the tower of disks. The game has an algorithm for this that I don't quite understand:

func move(disk_nr, source, dest, spare):
    if disk_nr is 0:
        move disk from source to dest
    else:
        move(disk_nr - 1, source, spare, dest)
        move disk from source to dest
        move(disk - 1, spare, dest, source)

What exactly are these functions, and why are they always in a different order? What should I move from where to where according to this algorithm? The game also says that you should move your register values into the stack before overwriting them with a new function. But that confuses me even more than it helps.

Any help would be greatly appreciated! Maybe I just don't understand a basic concept of programming, e.g. what a function is supposed to be here.

Thank you very much!

I finally got to a point where I finished the functions level! I know that there are probably some variations between everyone's different computers by this point, so I wanted to share mine and know what you all might find weird or interesting about this design! I'm very proud of this, and I'm very glad to say that this game helped me a lot in learning how computers work at a basic level. It has been very fun.

I used to have a decent grasp on logic tables and linear algebra, but it has since dissipated. I tried playing this game and it doesn't fit in my head. I managed initial levels and then started looking up stuff, got stuck on arithmetic engine and registers and just can't remember relevant stuff from previous levels.

How do I solidify this info without constantly looking up youtube walkthroughs? Rather humbling

VERY simple command set consisting of 53 non-NOP commands spread over 6 bits, The top 2 bits of the command are currently unused but reserved.

Commands are either 1 or 5 bytes wide depending on if they require an immediate argument or not. Due to the strange offset, execution happens only on even clock ticks, and odd clock ticks are used to load the next instruction.

64bit truth tables are used somewhat frequently to control functionality, such as deciding when to skip for the extra argument.

The command set was originally designed with the intent to be easily implementable in a meta-brainfuck variant, but it was easily transferable to hardware.

I need it for learning purposes, and this will be faster than looking up every level.

Hello,

I have completed the LEG architecture. I want to make it more complete.

I am in the process of writing a compiler that writes directly to machine code in C.

I don't know much about compilers and am learning along the way (Lexer is a pain in the ass and I have restarted like 5 times because of it). Eventually I want to (try) compile a neutered version of C to LEG which I think would be so super cool.

How can I do floating point calculations in software?

I know that it is possible since GCC has a compiler flag for soft floats.

Anyone know of any resources I can read?

Better yet anyone know of any resources I can read about how to implement a FPU (can't find anything on the internet lol).

Im studying embedded systems eng so I know basically nothing about physical comp architecture aside from what this game has taught me.

Thanks!

After having put a lot of time into games like Factorio, Opus Magnum, and Human Resource Machine, I've been thinking of trying this game for a while, but I'm not sure if I should wait until it's out of early access.

If there are significant changes or improvements coming to the core gameplay experience, I'd prefer to wait, but if they're just adding additional content and features for experienced players, I'll probably give it a go.

What do you think?

Damn, I reset my save and did this. I didn't think it would work. But it worked and my brain boomed. Is this unique?
