memory-mapped I/O

Post by karim »

Does memory-mapped I/O mean that certain addresses are reserved for devices from the linear address space? For example, if the processor is 32-bit, that means we have 4 GB of linear address space, which is all the addresses the CPU can handle. So we take a small part of these addresses and assign them to devices, right?"

You don't need to ask the same question twice.
