INTERRUPT LATENCY AND INTERVAL TRACKING

Secure circuitry detects a latency between when an interrupt occurred and when the interrupt was released in correspondence with handling of the interrupt. The secure circuitry detects an interval between consecutive occurrences of the interrupt. In response to either or both of the latency exceedin...

The secure circuitry detects an interval between consecutive occurrences of the interrupt. In response to either or both of the latency exceeding a latency limit and the interval exceeding an interval limit, the secure circuitry performs an action.
