WebComputers with memory-mapped I/O can use memory-type instructions to access I/O data. It allows the computer to use the same instructions for either input-output transfers or for memory transfers. The advantage is that the load and store instructions used for reading and writing from memory can be used to input and output data from I/O registers. WebThe IOP operates independent from CPU and transfer data between peripherals and memory. The communication between the IOP and the devices is similar to the program control method of transfer. And the communication with the memory is similar to the direct memory access method.
