WebInterrupt-driven I/O Interrupt-driven I/O attacks the problem of the processor having to wait for a slow device. Instead of waiting, the CPU continues with other calculations. The device interrupts the processor when the data is ready. The data transfer steps are still the same as with programmed I/O, and still occupy the CPU. WebThe only issue is a slight increase in latency - neglible in most use cases. Since the polling is usually realized in hardware IIRC, software only gets notified if there is new data. On …
