FWIW, I did this program and assembly / digital design (assuming you mean computer architecture) was pretty well covered in the OS class. They use the Patterson + Hennessey book that many other large universities seem to use. That class was one of the ones that took me the longest since the only background I had was going through the nand to tetris book a few years before. Definitely no compilers or linear algebra though. Personally, I plan on going through some self-study of those topics at some point or another, but I've had a hard time prioritizing them over what seems like more relevant material to the area I've been working in (full stack web dev).
