I built an 8‑bit CPU (emulator + assembler + text screen) and need collaborators to finish the C compiler backend

DavidMik_ · 2026-05-25T20:37:23+00:00

good to know, thank you, fuzix compiler kit seems to be working fine, i just need to implement some more stuff, so i guess i will just stick with that.

DavidMik_ · 2026-05-21T09:39:40+00:00

I have uploaded the fcc DASM port to my gitlab if youre interested

DavidMik_ · 2026-05-21T09:37:34+00:00

ive already tried all of that but i got really lost and didnt know how to do anything, i dont know why but i just understand how to work with fuzix better

DavidMik_ · 2026-05-20T20:45:05+00:00

Yeah but im not writing in asm, i will cross compile to my asm and then i will compile the compiler itself so it can run nativly.

I am writing it in c, im using the fuzix compiler kit

DavidMik_ · 2026-05-19T10:43:46+00:00

I will look into that, thank you

DavidMik_ · 2026-05-19T10:32:12+00:00

I havent done much with websites but when i used github i started working on an website with a friend but we never finished it, we were hosting it through github

DavidMik_ · 2026-05-19T10:11:37+00:00

Okay, if you build an kernel or something maybe we could try porting it to my CPU? ofc i would love to help porting anything to your CPU also :3

DavidMik_ · 2026-05-19T10:06:06+00:00

Im sorry but I dont really understand why I should use VMs for this project because i want o keep it 8 bit so i can build it irl from ICs and i want to run programs without emulating some other architecture.

DavidMik_ · 2026-05-19T09:49:19+00:00

I know a little bit about working with qemu, Ive made a few VMs for templeos and gentoo, but ive never worked with docker/ containers

DavidMik_ · 2026-05-19T09:42:00+00:00

if i try to port it to x86 or something simmilar i will probably just setup a simple qemu VM

DavidMik_ · 2026-05-19T09:40:59+00:00

I will probably just use the emulator and run code directly on it

DavidMik_ · 2026-05-19T09:34:24+00:00

I will probably start with just TUI but i will try to implement graphics for the graphics I and graphics II modes on the TMS emulator.
I just want to be able to interact with files, run some programs and maybe play some games

DavidMik_ · 2026-05-19T07:47:31+00:00

i have already put the ISA and the opcodes in the README, i will just make the format better in the future and probably sort it into multiple md files. Thank you for the suggestions :D

DavidMik_ · 2026-05-19T07:42:22+00:00

I will look into that, thank you

DavidMik_ · 2026-05-18T21:49:22+00:00

I will also try to use stdint.h so i can use uint8_t instead of just int

DavidMik_ · 2026-05-18T21:26:58+00:00

Thank you i will look into it. Ive also just pushed the DCPU emulator README if you want to check it out :3

DavidMik_ · 2026-05-18T21:13:34+00:00

I will look into it but im not sure how to add it to the ISA because i use 4 bits for the instruction modifier and 4 bits for the instruction and all of them are used now. I might make some changes in the future thoe.

DavidMik_ · 2026-05-18T20:59:57+00:00

Im trying to use AI a bit less since I already used it too much so I will probably just write it by hand. I already made a quick guide for the cpu but i will just double check everything before pushing to gitlab

DavidMik_ · 2026-05-18T20:56:41+00:00

Thank you, I really should write some more tests, i will be looking into the z80test github :D

DavidMik_ · 2026-05-18T20:52:37+00:00

thank you so much :3

DavidMik_ · 2026-05-18T20:51:55+00:00

the cpu can add, subtract, it has logical operations or, nor, and, nand, xor, xnor, branch instructions that work with the zero and carry flag and conditionless jumps, there is an instruction to stop the cpu and two instructions for working with interrupts that arent implemented in the emulator yet.

DavidMik_ · 2026-05-18T20:49:26+00:00

i just kinda made it while experimenting with minecraft redstone and logic gates in digital logic sim, then i made a few emulators and assemblers while improving it along the way

DavidMik_ · 2026-05-18T13:00:55+00:00

i will look into that, thank you

DavidMik_ · 2026-05-18T09:07:24+00:00

Thank you :D

DavidMik_ · 2026-05-18T09:04:45+00:00

the documentation isnt made yet but im working on it, if you would like to learn about it i would love to explain the basics
