Question

For real time operating systems, interrupt latency should be

a) Minimal
b) Maximum
c) Zero
d) Dependent on the scheduling

Answer 1

In real-time operating systems, interrupt latency should be minimal to ensure quick responses to time-sensitive tasks.

Step-by-step explanation:

For real-time operating systems, the goal is to have interrupt latency be as minimal as possible. Interrupt latency is the time taken by the system to start the execution of the interrupt handler after the interrupt is generated. A minimal latency is crucial in a real-time system, as it ensures that the system can respond quickly to time-sensitive tasks, maintaining system reliability and performance. In contrast, a maximum latency would lead to delays, a zero latency is not practically achievable due to physical constraints, and while the latency could be dependent on the scheduling, in the context of real-time operating systems, it is generally desired to minimize it regardless of the scheduling algorithm.
