Is there some information source or technical draft (something like RFC for networking) describing implementation of particular instructions (e.g. mov, jmp, je, jle, inc, …) for Intel architecture?
Some general talk is on wikipedia but I’d like to know perfectly what’s happening under the hood.
Thank you
They are generally implemented with micro-code, you can read up on that here, it mostly depends on the type of processors you are looking into (embedded, multi-core, power saving etc), Intel has some architecture design details here (the rest of the manuals also have various more minor details).
Its a bit old school now, but you should also find this helpful and interesting, it details the in depth design of the Pentium 4 series of processors, including instruction set implementation.
