I learned low level programming while at Intel, working with one of their performance teams; so, nothing written. In general, though, assembly is more expressive than higher level languages; it lets you “tighten up” the code the computer executes, reducing work & bandwidth. Specifically, a guy named Mike Abrash taught me some of this stuff, and he’s got some books explaining the theory in terms of practice.
