Consider a system with 3 I/O devices
- Printer (priority of 2)
- Disk (priority of 4)
- Communication line (priority of 5)
-
Higher priority is indicated by high numerical value.
User program begins at t = 0 and the multiple interrupts occur at following time instances
- At t = 10, Printer interrupt occurs
- At t = 15, Communication interrupts occurs
- At t = 25 Disk interrupt occurs
- Show the time sequence of multiple interrupts, assuming that service routine for Printer interrupt takes 30 time units, Disk interrupt takes 10 time units, and Communication interrupt takes 5 time units.
