interruptlatency
Interrupt latency is the time between the moment an interrupt request is generated by hardware and the moment the processor begins executing the corresponding interrupt service routine (ISR). It is a measure of how quickly a system can respond to an external or internal event that requires attention.
The latency typically includes several stages: the interrupt request being asserted, the interrupt controller acknowledging the
Common factors affecting interrupt latency include the type of interrupt controller (for example, legacy PICs, advanced
In real-time and safety-critical contexts, latency is often bounded and measured as worst-case or maximum latency,
