Memory-mapped I/O uses the same address space to address both memory and I/O devices. ... So a memory address may refer to either a portion of physical RAM, or instead to memory of the I/O device. Thus, the CPU instructions used to access the memory can also be used for accessing devices.
What is the difference between memory mapped and IO mapped?
No separate control signal required since we have unified memory space in the case of Memory Mapped IO. Special control signals are used in the case of IO Mapped IO. Arithmetic and logical operations are performed directly on the data in the case of Memory Mapped IO.
What are I O mapped and memory mapped I O schemes?
I/O is any general-purpose port used by processor/controller to handle peripherals connected to it. I/O mapped I/Os have a separate address space from the memory. ... A separate signal is used for addressing an I/O device. Memory-mapped I/Os share the memory space with external memory.
