Memory-mapped I/O performing I/O between CPU and peripheral devices (I/O) in a computer. In memory mapped I/O uses same address space to address both memory and I/O i.e. some address are reserved for I/O devices and rest used for memory. So it works in same way as b/w CPU and memory.

Memory mapped I/O involves:
Memory mapped I/O is a technique used in computer architecture to allow input/output (I/O) devices to communicate with the central processing unit (CPU) in the same way as memory. It involves transferring information between the CPU and I/O devices in the same way as between the CPU and memory.
Explanation:
Memory mapped I/O is a method of I/O communication where the I/O devices are treated as if they are memory locations. This means that the CPU can read from and write to the I/O devices using the same instructions and addressing modes as it does for memory.
Transferring information between the CPU and I/O devices in the same way as between the CPU and memory:
In memory mapped I/O, the I/O devices are assigned unique addresses in the address space of the CPU. These addresses are mapped to the corresponding I/O registers or buffers of the devices. When the CPU wants to communicate with an I/O device, it simply reads from or writes to the memory address associated with that device.
Advantages of memory mapped I/O:
1. Simplicity: Memory mapped I/O simplifies the communication between the CPU and I/O devices by treating them as memory locations. This eliminates the need for special I/O instructions or separate I/O registers.
2. Efficiency: Memory mapped I/O allows the CPU to access I/O devices using the same bus and memory controllers used for memory access. This eliminates the need for separate I/O controllers and improves system performance.
3. Flexibility: Memory mapped I/O provides a flexible framework for I/O device interaction. It allows I/O devices to be easily added or removed from the system without requiring significant changes to the CPU or memory architecture.
Conclusion:
Memory mapped I/O is a technique that simplifies and improves the efficiency of communication between the CPU and I/O devices. It allows the CPU to access I/O devices using the same instructions and addressing modes as it does for memory. This makes the system design simpler, more efficient, and flexible.
