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.

Mintia: my paging operating system written in a custom language for a custom architecture
Someone did a verilog implementation of the instruction set, but it only gets to the boot rom prompt because they didn't implement the TLB. It's a cool long term goal for me to do a full system implementation in verilog or something, but I'm just one person and there's a lot to do, so I'm not sure I'll get around to that any time soon.
What are some alternatives?
