You're right, I just checked out the older ARM Cortex, like M0 and such, and they don't look very complex. It probably get's messy once you have more advanced features like a cache, branch prediction, power saving etc. I really don't want to see the internals of a modern Intel/AMD CPU, or even an IBM one. Nobody can ever fully understand how it works starting at the lowest level, there are just too many features in there.
