Aristotle (Socrates, Diotima), Pythagoras, Blaise Pascal, George Boole, Ada Lovelace, Alan Turing, Gottfried Wilhelm Leibniz, Isaac Newton, Bertrand Russell, Gordon Moore, Dennis Ritchie, Bill Gates, Steve Wozniak, and Steve Jobs ...
... just to introduce #Libre8.
I've also written a #Libre8 emulator in Rust, supporting and running the exact same binaries as the Logisim-Evolution schematic, compiled with the exact same toolchain.
And the result could not be more satisfactory: over 9,000 times faster than the original tool.
Timing unaltered:
Hi buddy! If you already have a working assembler, just check this link (it’s what I use for #Libre8).
You would just need to replace the ASM (or pseudo-assembler) that MiniCCompiler generates.
In my case, I first wrote an assembler, which I still use today in this "C"→"ASM"→"BINARY" toolchain.
1/ One year on #BlueSky ✨ for #Libre8.
Thanks for being part of this journey! 😊

Well, it finally happened: #FMV (Full Motion Video) has arrived on the #Libre8 #CPU — along with other features like an impressive 4GB of RAM (for an #8BIT computer), #Internet connectivity, VGA output, a #C #compiler, and even a #ChatGPT client.
All built by me alone 😁😉

I’m excited to share a humble project: I recreated the Monkey Island intro as a schematic in #Logisim on my open-source CPU design, #Libre8. Seeing the game intro played in simulation has been a fantastic learning journey.

🔹 #AGC (1960s):
2 Mhz
15-bit +1-bit ECC WORD
32KB RAM (mag core)
36KB ROM (core rope)
Processor: Discrete silicon ICs (RTL-based)
🔹 #Libre8 (targeted to improve a processor from 1979, the Intel 8088):
2 Mhz
24-bit WORD
16MB RAM
36-bit ROM
Custom logic gate CPU + GPU
Fast forward: I’ve technically built a #computer more powerful than the one that helped land astronauts on the #Moon. 🚀🌙
Yes, #Libre8 outperforms the Apollo Guidance Computer (#AGC) in almost every spec.
When I started #Libre8, my goal was simple: build something better than the #Intel 8088. An 8-bit CPU with clear logic, control, and memory I could understand and fully create from scratch. Logic gate by logic gate.
@developers.google.com Bluer skies look great on you!

In this #Libre8 demo, we loop a JMP from 00000000h 🌀 and watch how the IR, firmware, and control signals behave. Then we jump to 0x00 💥—an invalid byte—and crash the CPU. Time to reboot!

The fact is, if I understand your project correctly, you aimed higher. That's not bad, just more challenging.
I had to constrain #Libre8 to "just" be on par to the Intel's 8088, in system specs.
You're aiming to do a dual-core that is on par to ARM or RISC, and I'm really hoping you succeed. 👏😉
In #Libre8, as in any solid architecture, handling arithmetic errors is the programmer’s duty. Nothing is left to chance: divide by zero?
⚠️ You better catch it first. This video shows how to prevent disaster with elegance and control. 🧠💻

🔁 What happens when recursion gets out of control?
In systems like #Libre8, calling a recursive function can cause a StackOverflow.💥
🧠 This video breaks it down visually and shows why managing recursion and memory matters.
📟 If you're curious about what’s under the hood, this demo is for you.

Here you got all the videos about #Libre8 💻🎱, in chronological order: an #8bits #computer I started developing some years ago, that now can *almost* run standard C code.
The schematic, built upon #Logisim, it's firmware, writen in #Java, alongside the Assembler and C compiler, are #SoftwareLibre!
Additionally, I am working on new projects to capture in video, as porting other's people's C code, to my very own computer architecture, #Libre8.
.- I've found a Game of 1981 writen in C which is a perfect candidate to run on it -

Hi! I apologise for not posting anything in these last days, I've been just busy 😊.
I am currently emulating Dennis Ritchie when he wrote A and B before C, while implementing a HLPL. In my case I am doing for my very own architecture, #Libre8.
