GPLGPU walkthrough

The goal was to publish source code to a GPU that is register compatible with the late 90’s era Number Nine “Ticket To Ride IV” GPU. Although the project didn’t meet its funding goal, the person behind it later published the code on github.

Despite the fact that this is an older design, it has lots of stuff that is worth studying. It’s interesting to compare this design to the VideoCore GPU that I walked through in a previous post. While there are some fundamental differences, there are surprising number of functions that are similar, which shows how modern GPUs evolved from earlier ones.

A walkthrough of the GPLGPU as well as some history and backstory of the Number Nine “Ticket To Ride IV” GPU.
