keskeytysjärjestelmä
Keskeytysjärjestelmä, often translated as interrupt system or interrupt handler in English, is a fundamental concept in computer operating systems and hardware design. It refers to a mechanism that allows hardware devices or software routines to signal the processor that an event requiring immediate attention has occurred. When such an event happens, the processor temporarily suspends its current task, saves its state, and then executes a specific piece of code, known as an interrupt service routine (ISR) or interrupt handler, to deal with the event. Once the ISR is complete, the processor restores its previous state and resumes the interrupted task.
Interrupts are crucial for efficient multitasking and responsiveness. They enable the system to handle diverse events
The Keskeytysjärjestelmä involves several components: the interrupt controller, which prioritizes and routes interrupts; the interrupt vector
