Hi all,
below given is an explanation of i/o(port) mapped i/o.
i want to know why mem mapped i/o is faster than i/o mapped i/o.
Another form of IO commonly supported is Port Space. This is a range of
addresses separate to the normal memory address space. Access to these
addresses is generally not as fast as accesses to the memory mapped
addresses, and it also has a potentially smaller address space
