Is all of this correct? Is this true? Because:
That would mean main memory is actually attached and mapped as I/O or not? The CPU cache is the actual memory that uses this easy systembus (address data control bus) concept. And when we talk about the simplest form of physical addressing what do we mean? (0x0FFF, 010FFh) Memory locations of course. But that's not the case, since at least the 90`s when the Front-side bus concept was introduced.
