Detailed explanation-1: -A device’s interrupt priority is selected based on two criteria: its maximum interrupt latency requirements and the device driver’s interrupt execution time. The interrupt latency requirement is the maximum time within which an interrupt must be serviced.
Detailed explanation-2: -TRAP is the internal interrupt that has the highest priority among all interrupts except the divide by zero exception.
Detailed explanation-3: -It is a system responsible for selecting the priority at which devices generating interrupt signals simultaneously should be serviced by the CPU. High-speed transfer devices are generally given high priority, and slow devices have low priority.
Detailed explanation-4: -We can use a polling procedure to identify the highest-priority. There is one common branch address for all interrupts. The program that takes care of interrupts begins at the branch address and polls the interrupt sources in sequence. The order in which they are tested determines the priority of each interrupt.
