The logic circuit Christmas tree. The only fun thing I brought from Computer Architecture classes.
Well, to be fair the classes (and Logisim) were actually fun, but the assignments and exams were appalling.

Hey, computer enthusiasts! 🌟 In this video I invite you to join me on a one-of-a-kind adventure: #Sonic the Hedgehog racing at full speed across the core of my homebrew computer, #Libre8, designed and built entirely from scratch!

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.

⚠️Overflow and underflow: two classic computing bugs with surprising consequences. 🖥️ In this video, I show how they work on #Libre8 —and how one became a feature in Sid Meier’s Civilization.

I’ve made another #BadApple video—this time running on my own #GPU for my custom computer design, #Libre8! 🎱💻

This serves as a demo of the Libre8 GPU’s capabilities. Huge thanks to the #Logisim devs who boosted simulation speed by over 20×! Super excited to share this! 😁

#opensource #tech #cpu

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!

Finally finished the tiny 8 bit RISC #logisim implementation with two cores. I won't put it on an FPGA since it is inefficient but it shows that you can make any CPU multicore with a little memory subsystem magic. It can synchronise via an address mapped address reservation mechanism (address lock)

I have finally designed an accelerated #GPU for #Libre8, using #Logisim!

Check out the demonstration, featuring this canonical sequence from #FindingParadise, the second installment in the #ToTheMoon series developed by #FreebirdGames.

Liked it? Would you mind sharing? 💞

Still alive! #Portal x #Libre8!! 💻🎱

Currently reworking the #Logisim design for upcoming videos! #Electronics, #Gaming, #PublicDomain #Movies and restorations, and a lot more, in my Youtube channel!

Welp, i did everything except for the GPU: i now have my main flagship ISA that is basically my counter ISA to RISC-V and i glued two of my Picowizards (in #Logisim) together with some memory magic. Brain, i love that you did that but i want a GPU so that i can finally use them

#BadApple x #ToTheMoon x #Watchy in this #ESP32 project!

I have also designed a #CPU, just using logic gates.

It runs in #Logisim and its name is #Libre8!

I designed an #8bit #computer using #Logisim, an electronic circuit simulator.

And I called it #Libre8, because it is #OpenSource.

Here a short sneek peek into the current progress of the deep pipelined 8 bit CPU in #Logisim. I am still unsure if i should implement it in SystemVerilog since i doubt i can clock it much faster. But welp, lets see how it will look when its done

The prototype 2 32 bit NISC/RISC hybrid ISA comes along quite well! It should be able to do a lot of stuff in parallel in a single instruction/glue together multiple standard RISC operations. Lets see if i can implement it in #Logisim without going into MUX mania

He diseñado un #ordenador de #8bits usando #Logisim, un simulador de circuitos electrónicos.

Y lo he llamado #Libre8, porque es #CódigoAbierto.

Okay, the syscheck is debugged. Now i can start with the actual BIOS i need before i can jump into the OS for the 16 bit CPU. #Logisim

The 32 bit CPU is now turing complete! Now i have the urge to dip into superscalarity since the design per se currently isn't complicated. Ah well, screw this, going 2 pipeline in order. #Logisim
