Hardware interrupt sequence

WebIn a computer, an interrupt request (or IRQ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead.Hardware interrupts are used to handle events such as receiving data from a modem or network card, key presses, or mouse movements.. Interrupt lines are often … WebHardware interrupts are the highest priority scheduling mechanism in most real time operating systems (Figure 8.11). The keypad control function is an interface to the environment (operator console) and will use a hardware interrupt to signal the keypad control actions. This priority will be at a lower priority than the motor control interrupt.
