Web19 jan. 2024 · Interrupts are commonly used to service hardware timers, transfer data to and from storage (e.g., disk I/O) and communication interfaces (e.g., UART, Ethernet), handle keyboard and mouse events, and to respond to any other time-sensitive events as required by the application system. Why are interrupts generated? WebThis problem can be overcome by using interrupt initiated I/O. In this when the interface determines that the peripheral is ready for data transfer, it generates an interrupt. After receiving the interrupt signal, the CPU stops the task which it is processing and service the I/O transfer and then returns back to its previous processing task. theo sanderson codon2nucleotideWeb22 apr. 2015 · Interrupt-driven I/O. Primary disadvantage of programmed I/O is that CPU spends most of its time in a tight loop waiting for the device to become ready. This is called busy waiting. With interrupt-driven I/O, the CPU starts the device and tells it to generate an interrupt when it is finished. Done by setting interrupt-enable bit in status register. shtfp an.com

WebAs we have seen in interrupts, the input from I/O device can arrive at any moment requesting the CPU to process it. Polling is a protocol that notifies CPU that a device needs its attention. Unlike in interrupt, where device tells CPU that it needs CPU processing, in polling CPU keeps asking the I/O device whether it needs CPU processing.
