Abstract
High frequency detection of interrupts includes incrementing a count by a first number in response to at least one interrupt. The count is decremented by a second number in response to a clock if the count is greater than zero. An interrupt rate is determined from the count. A fault collection unit (FCU) is updated when the interrupt rate exceeds a threshold.
