The difference between Isolated and Memory mapped I/O are

Isolated I/O Memory Mapped I/O
Memory and I/O have separate address space Both have same address space
All address can be used by the memory Due to addition of I/O addressable memory become less for memory
Separate instruction control read and write operation in I/O and Memory Same instructions can control both I/O and Memory
In this I/O address are called ports. Normal memory address are for both
More efficient due to separate buses Lesser efficient
Larger in size due to more buses Smaller in size
It is complex due to separate separate logic is used to control both. Simpler logic is used as I/O is also treated as memory only.
