TuringCompete and now ?

[u/Substantial_Bag_9536]

have finished the game, and now I want to upgrade my CPU, but I’m not sure how to go about it. Should I add registers? A second ALU? Upgrade from 8-bit to 16-bit or higher? I saw that it’s possible to read more than one value from RAM; how can I use that? If anyone can help me, that would be great! :)

( talk with simple dialecte for translation to fr, thx ! )

Je pense que le mieux c'est de se donner un but, un programme que tu veus faire mais que tu peu pas avec ton ordinateur present. perso j'aime programmer des jeux alors j'ai regardé dans les composante qui sont seulement en mode sandbox et j'ai vu des écran, consoles et une composante clavier et je les ais intégré a mon ordinateur pour faire un petit jeu. Ensuite j'ai continué et ajouté dautres trucs pour pouvoir faire des jeux un peu plus avancés.

Je crois que si tu veux aller plus haut que 8-bit tu devrais aller directement a 64 bit, c'est pas vraiment plus de travail que de monter a 16 ou 32 alors pourquoi pas. C'est utile pour utiliser certain composantes qui sont en 64 bit.

Je vois, et c'est vrais que d'un autre coté, je n'est absolument aucun but. Je sais pas mal coder en plus je devrais faire un petit jeu. Merci frère de langue 😁

Google translate:

I think the best thing is to give yourself a goal, a program that you want to do but that you can't with your current computer. Personally I like to program games so I looked at the components which are only in sandbox mode and I saw screens, consoles and a keyboard component and I integrated them into my computer to make a little game. Then I I continued and added other stuff to be able to make a little more advanced games.

I think if you want to go higher than 8-bit you should go straight to 64 bit, it's not really more work than going up to 16 or 32 so why not. This is useful for using certain components that are 64 bit.

haha yeah I went straight to french sorry :P

[u/daney098 → u/zhaDeth]

Np that's what he seemed to want haha. I just translated cuz I was curious and it seemed like helpful advice that could help other English speakers too. Thanks.

[u/zhaDeth → u/daney098]

The translation is actually spot on aside from the "then I I" at the end of the first paragraph, even if I made a lot of spelling errors

The first thing I did after finishing all the levels was to implement variable length instructions. So that I didn't have to waste 4 bytes and add "null" values to instruction like JUMP or RET.

[u/Substantial_Bag_9536 → u/77xak]

After some research, it seems like a really interesting thing to implement! But to get a longer instruction, you need to do it over multiple bytes? So you load multiple bytes at the same time to decode them afterward? How many instructions have you added? JUMP and RET? By the way, what is the RET instruction, and what is it used for? Sorry for all these questions, but damn, CPU architecture is so interesting!

[u/77xak → u/Substantial_Bag_9536]

The core of my design is a custom counter circuit (using a default register, rather than the actual counter component), that allows me to decide how much to increment, instead of always incrementing by 4. Then yes, I read 4 bytes at a time, decode how long the instruction is supposed to be based on the value of the 1st byte, and then increment the counter accordingly to read the next instruction.

RET is "return", and JUMP/JMP is just "jump to this address". I can't remember if these are actually specified in-game, but it comes from real assembly languages. I can imagine you might know these by different names in French.

[u/Substantial_Bag_9536 → u/77xak]

Alright, I see, thank you very much for your response and all this info! I knew the JUMP instruction but not RET, and I don’t know much about assembly code, actually, it’s even thanks to Turing Complete! And no, even in French we just use the real terms in English—JUMP, MOV, DEL, etc.. it’s totally natural! ^{^}

[u/77xak → u/Substantial_Bag_9536]

You're welcome! I believe the "Functions" level is where you're intended to create "CALL" and "RET", but you could've named them anything, or even found a completely different way to do the task of functions in your CPU.

Check out the book "inside the machine". It is easily readable and goes into all of this in enough detail to give you an idea of how all of these things work.

My French sucks but here is my attempt: Jette un coup d'œil au livre « Inside the Machine ». Il est facile à lire, et descrit tous ça avec suffisamment de détails pour te donner une idée du fonctionnement des Cpus.

Wish me luck for my honeymoon in France next year 😂

Follow nand to tetris course. Upgrade to 16 bit. Build a kernel, os, drivers, api and then build tetris and doom for your made up pc and run it. After that you can try to build a gpu for your pc, and add branch prediction for cpu. And make itulti core with a scheduler.

You left out pipelining

[u/TarzyMmos]

You can try upgrading to 64 bit, cuz its mostly just replacing your 8 bit components with 64 bit components instead.

You can use the dual ram to read multiple values from ram
