Expand hardware technical skill

Unlike software, there are limited resources on Udemy or Coursera to let you expand hardware related technical skills. When it comes to AI or ML, it's even harder to find study materials to help you understand the AI/ML chip architecture. I don't find a place to teach you AI/ML chip design other than reading papers. I am not really good at reading papers. Does anybody here know better ways to study AL/ML chip? Interesting hardware topics are: DNN hardware architecture and cons/pros of particular architecture. etc.
