Hardware, Embedded Systems In the world of alternative OS development, portability across multiple architectures is a challenging goal. Sometimes, it may be intrinsically hard to come up with hardware abstractions that work well everywhere, but many times the core problem is one of missing information. Here, I aim at learning more about the way non-x86 architectures deal with CPU IO ports, and in particular how they prevent user-mode software from accessing them.

Isn't that one of the main reasons the Amiga rocked so hard, yet only had a 7.14mhz CPU (pretty sure that was the speed). Most things were handled through the bus, instead of the CPU having to handle all the I/O.
