1/ @tinytapeout 7 just closed and these two tiles host my design! If it works, it will generate explorable terrain 'voxels' similar to the VoxelSpace Comanche 1992 game engine.

After 31 years, a mysterious version of #Doom 1993 has been uncovered!
Happy birthday, Doom! 🥳
(stay tuned for more on this, mastodon.online/@sylefeb)

The new Gabor noise in Blender 4.3 looks really promising for quickly creating some sick stylized shapes ✨

Want to use #WebGPU together with #SDL3?
After recently upgrading #sdl2webgpu, I introduce #sdl3webgpu, little SDL3 extension to create WebGPU surface!

Beginning FPGA Graphics now covers @RadionaOrg #ULX3S (ECP5) in addition to the @DigilentInc Arty / Nexys Video and iCEBreaker. Four years after it began, I continue to update this series to make #FPGA development accessible. 👷 projectf.io/posts/fpga-graph…

It’s a #COMET! ☄️
The #digital DEC705 is a gate array made in the late 1980s. Enjoy the awesome microstructure!
It’s a #COMET! ☄️
A half-finished meteor/comet #silicondoodle is placed on the top corner of this vintage IC made by #Digital (#DEC).
COMET is a microprogrammable computer specifically designed to emulate the VAX-11 microarchitecture. VAX (Virtual Address eXtension) was invented in the late 1970s and allowed 16-bit systems to address up to 4GB memory. A variety of chips have this doodle but I am not sure why the comet is not complete on this DC705…

1/ If you feel adventurous and want to try both @tinytapeout (make your own chip!) and #Silice I prepared a template for tt09 (61 days to go!).
github.com/sylefeb/tt09-sili…
Be warned: I am waiting for my tt07 and tt08 designs to come back to realize my mistakes 😅.

2/ I followed the @tinytapeout approach of doing the entire synthesis in github actions, with #Silice seamlessly integrated in the mix. Write your code, commit push, and get back an ASIC design ready to submit to Tiny Tapeout !

I've created a series on RISC-V assembler for software developers. The first part introduces #RISCV, then looks at load immediate, addition, & subtraction. I also cover sign extension & pseudoinstructions. No ads, just content 🚀 projectf.io/posts/riscv-arit…

I love fusing retro with modern sounds, and my latest track is no exception. Certain parts of this song were crafted using the #Amiga. Check out the 4-channel version here. If you enjoy it, please support me by adding it on your favorite music service👾

The first version of GBA core for Tang FPGA is ready 🚀🚀. It's early stage - only some games are working, no save-to-sdcard yet. The project took a while, and I'll blog about the details. For now enjoy this little video and get the core from: github.com/nand2mario/gbatan…

@wren6991 added optimized RISC-V float add/sub/mul to the Raspberry Pi Pico SDK for RP2350 - nice speed up over the stock GCC lib as shown here! More to come no doubt!
