Keskeytyskäsittelijöitä
Keskeytyskäsittelijöitä, often translated as interrupt handlers or interrupt service routines (ISRs), are essential components in computer systems responsible for managing hardware interrupts. When a hardware device needs the processor's attention, such as a keyboard press, a network packet arrival, or a disk operation completion, it generates an interrupt signal. This signal diverts the processor from its current task to execute a specific piece of code.
The interrupt handler is this specialized code. Its primary role is to acknowledge the interrupt, determine
The design and efficiency of interrupt handlers are critical for system responsiveness and performance. Long-running interrupt
