Interrupt latency is the time elapsed between what?

[kumar_eee]

Interrupt latency is the time elapsed between:

1. Occurrence of an interrupt and its detection by the CPU

2. Assertion of an interrupt and the start of the associated ISR

3. Assertion of an interrupt and the completion of the associated ISR

4. Start and completion of associated ISR

To my knowledge the solution is no. 2
Interrupt latency is the time duration elapced between interrupt invoke and till the CPU starts its ISR.

right answer is No. 2
latency is due many factors;
priority,scheduling & other interrupts from devices.
