That is the domain of transistors, resistors, capacitors, and so on. That path will not make you a game programmer. If you did work on those systems in a game console it would be only for a very limited function; you would be one member of a team that works on the audio subsystem of the console.
That being said, I wouldn't start down that route with a college book. You are better off starting with a "My First Microcontroller" style project book that comes with a bunch of components.
Oh , so there are multiple books that I will need to study in order to learn computer engineering? So I will need to get a book on each part bascially? If so will this book tell me what I will need to learn next or hint me toward what I need to learn after micro controllers...I have a little expierence with them, but not much at all. I'm looking fo everything that I will need to study. You said and so on, so that sort of leaves me at a blank spot because I havn't really found anything useful on computer hardaware engineering on the internet except very poorly and discrete written information.
