As a system software developer, I had to learn about ARM processors, so I looked at the specs and googled them. I didn't understand the unfamiliar terms, and ARM processors were so difficult that I gave up learning several times. However, after listening to this lecture, I felt like I had discovered a completely different world. The explanations were easy to understand, so I understood all the terms and flow that I didn't know, and the parts that I was stuck on were sorted out. I highly recommend this lecture to developers who want to learn ARM!
