FuryGpu – Custom PCIe FPGA GPU

1. verilog-pcie

   1 8 1,268 6.5 Verilog

   Verilog PCI express components

   

   The GPU uses this: https://github.com/alexforencich/verilog-pcie . And there is an open-source 100G NIC here, including open source 10G/25G MACs: https://github.com/corundum/corundum

2. InfluxDB

   www.influxdata.com featured

   InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

   

3. RasterIX

   2 1 90 7.6 C++

   OpenGL 1.x implementation for FPGAs

   

   Similarly there is this: https://github.com/ToNi3141/Rasterix

   Would be neat if someone made an FPGA GPU which had a shader pipeline honestly.

4. gplgpu

   3 5 666 0.0 VHDL

   GPL v3 2D/3D graphics engine in verilog

   

   > 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

5. picodvi

   4 33 195 0.0 C

   Discontinued [Moved to: https://github.com/Wren6991/PicoDVI]

   The RP2040 is a great MCU for playing with graphics as it can bit bang VGA and DVI/HDMI. There's some info on the DVI here: https://github.com/Wren6991/PicoDVI

   I wrote a couple of articles on how to do bit banged VGA on the RP2040 from scratch: https://gregchadwick.co.uk/blog/playing-with-the-pico-pt5/ and https://gregchadwick.co.uk/blog/playing-with-the-pico-pt6/ plus an intro to PIO https://gregchadwick.co.uk/blog/playing-with-the-pico-pt4/

6. PhobGCC-doc

   5 27 235 4.7

   Documentation for the PhobGCC

   

   I used "composite" (actually monochrome) video output software on the RP2040 for an optional feature on the PhobGCC custom gamecube controller motherboard to allow easy calibration, configuration, and high-frequency input recording and graphing.

   Pictures of the output here: https://github.com/PhobGCC/PhobGCC-doc/blob/main/For_Users/P...

7. microgpu

   6 1 17 7.7 C

   2d focused GPU for resource constrained microcontrollers

   

   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.

8. NyuziProcessor

   7 10 2,089 3.1 C

   GPGPU microprocessor architecture

   

   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.

10. FPGA_DisplayPort

    8 3 287 10.0 VHDL

    An implementation of DisplayPort protocol for FPGAs

    

    There is an open-source DisplayPort transmitter [1] that apparently supports multiple 2.7 Gbps lanes (albeit using family-specific SERDES/differential transceiver blocks, but I doubt that's avoidable at these speeds). This isn't PCIe, but it's also surprisingly close to PCIe 1.0 (2.5 Gbps/lane, and IIRC they use the same 8b/10b code and scrambling algorithm).

11. graphics-gremlin

    9 13 532 3.0 Verilog

    Open source retro ISA video card

    

12. VGA

    10 1 3 6.0 Verilog

    Verilog implementation of a VGA compliant with the VGA (Video Graphics Array) standard. Omar Mongy (by OmarMongy)

    

13. Frix

    11 1 68 - Verilog

    IBM PC Compatible SoC for a commercially available FPGA board

    

14. miaow

    12 1 1,138 - Verilog

    An open source GPU based off of the AMD Southern Islands ISA.

    

    what about projects like https://github.com/VerticalResearchGroup/miaow ?

15. corundum

    13 30 1,908 8.3 Verilog

    Open source FPGA-based NIC and platform for in-network compute

    

    The GPU uses this: https://github.com/alexforencich/verilog-pcie . And there is an open-source 100G NIC here, including open source 10G/25G MACs: https://github.com/corundum/corundum

16. Sentinel-65X

    14 1 22 7.4 C

    A cost-reduced 65816-compatible retrocomputer

    

    You might find the Sentinel 65X interesting in that the guy behind it basically said "the X16 is big and clunky and expensive, let's cut out that stuff".

    https://github.com/studio8502/Sentinel-65X

    It's not yet a deliverable product but watching the developers work on it has been an entertaining part of my doomscrolling diet.
