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.

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

FuryGpu – Custom PCIe FPGA GPU
This is my dream!
The last year I've been working on a 2d focused GPU for I/O constrained microcontrollers (https://github.com/KallDrexx/microgpu). I've been able to utilize this to get user interfaces on slow SPI machines to render on large displays, and it's been fascinating to work on.
But seeing the limitation of processor pipelines I've had the thought for a while that FPGAs could make this faster. I've recently gotten some low end FPGAs to start learning to try and turn my microgpu from an ESP32 based one to an FPGA one.
I don't know if I"ll ever get to this level due to kids and free time constraints, but man, I would love to get anywhere near this.
What are some alternatives?
