Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tiny GPU: A minimal GPU implementation in Verilog
Nice! I warmly encourage open-core GPU work.
Here's another: https://github.com/jbush001/NyuziProcessor

FuryGpu – Custom PCIe FPGA GPU
There's also Nyuzi which is more GPGPU focused https://github.com/jbush001/NyuziProcessor, but the author also experimented with having it do 3D graphics.

The WeeCee – Tiny Vortex86-Based DOS Gaming PC
You could probably layer a software implementation of the rasterization pipeline on top of a compute-focused open-source GPU architecture like Nyuzi: https://github.com/jbush001/NyuziProcessor/
I would expect a 2x slowdown over hardware rasterization, based on NVIDIA's work on such an approach, but this is probably fine if you're just trying to match Voodoo3 performance. And one could imagine bolting a minimal hardware rasterizer on top of Nyuzi to speed things up once the software implementation is working.

Sounds like the Nyuzi processor :D

FuryGpu – Custom PCIe FPGA GPU
> There's no open hardware GPU to speak of. Depending on license (can't find information?), this could be the first, and a starting point for more.
There's this which is about the same kind of GPU

Why is it bad to do floating point operations on FPGA?
If you learn better by looking at code, you can look at some Floating point work in my GPLGPU: https://github.com/asicguy/gplgpu/tree/master/hdl/math It's in verilog and has examples of adds, multiplies and reciprocals. Note that it's not fully 100% IEEE compliant. It doesn't handle NAN, +/- infinity. Happy to answer questions, but it'll be intermittent as I'm heading to Vietnam and China for vacation.

FPGA for graphics processing?
If you want to see how GPUs were designed in the late 90's check out my github repo: https://github.com/asicguy/gplgpu It's a VGA/ 2D/ 3D chip (pre shaders) from about 1998 ported to an FPGA.

Homebrew ray tracing GPU
Impressive work. PM me if you'd like any help on your project as it looks pretty cool. I've got 30 years experience in high speed FPGA/ ASIC design as well as some early graphics work: https://github.com/asicguy/gplgpu
