I started doing real-time work in the 1980s with 8-bit processors. Somehow I came out of it with a grayscale image of what is real-time, rather than black and white. It all depends on latency requirements and how much is offloaded to driver chips.

We used to have to ramp motors by changing the interval of our main processor's interrupts, and put motor windings for steppers out on parallel ports.

I don't think that should be necessary on your main CPU today.
