WebIf I/O devices generate interrupts, CPU does not need to wait for I/O completion OS initiates I/O operation at device CPU is free to do something else asynchronously during I/O execution; At later point, I/O operation completes and device triggers an interrupt. WebThe 82093AA I/O Advanced Programmable Interrupt Controller (IOAPIC) provides multi-processor interrupt management and incorporates both static and dynamic symmetric interrupt distribution across all processors. In systems with multiple I/O subsystems, each subsystem can have its own set of interrupts.
