Interesting to discover that this is a "lost art". I didn't graduate, but I did attend PUC-Rio for a while and I remember professor L. F. Bessa Seibel's lecture about that, as part of the INF1008 class (Introduction to Computers' Architecture), which is considered a basic first or second semester course for undergraduate CS students. That was just 5 years ago. Great class, great lecturer, btw
