Web26 apr. 2024 · Programmed I/O is a technique or approach that we use to transfer data between the processor and the I/O module. If we talk of programmed I/O and interrupted I/O, it is the responsibility of the processor to control the transfer from I/O to main memory as input and from main memory to I/O as output. On the other way, the DMA does not … WebThis is an instruction that performs the AND logic operation on pairs of bits in AC and the memory word specified by the effective address.. The result of the operation is transferred to AC. The microoperations that execute this instruction are: D 0 T 4: DR ← M[AR] D 0 T 5: AC ← AC ∧ DR, SC ← 0 The control function for this instruction uses the operation … WebMemory mapped I/O allows the CPU to control hardware by reading and writing specific memory addresses. Usually this would be used for low-bandwidth operations such as changing control bits. DMA allows hardware to directly read and write memory without involving the CPU. flowers around the corner
