On the hardware side (there are plenty of public resources about implementing graphics in software for the ground up), Jaymin Kessler's Jaystation2 and Jaystation3 dev blogs where he makes a GPU that runs on a FPGA might be useful http://maisonikkoku.com/ http://maisonikkoku.com/. This course also looks very useful from the hardware design standpoint https://courses.cs.washington.edu/courses/cse467/15wi/ https://courses.cs.washington.edu/courses/cse467/15wi/. GPU hardware design, unlike CPUs, seems to be much more esoteric with very little shared info due to the key players in the space and possibly all the patents. For graphics programming in general Graphics Codex looks really good (I haven't done the course, but I know people that have). https://graphicscodex.com/ https://graphicscodex.com/
