Abstract:
In an embodiment, a processor includes at least a first core. The first core includes execution logic to execute operations, and a first event counter to determine a first event count associated with events of a first type that have occurred since a start of a first defined interval. The first core also includes a second event counter to determine a second event count associated with events of a second type that have occurred since the start of the first defined interval, and stall logic to stall execution of operations including at least first operations associated with events of the first type, until the first defined interval is expired responsive to the first event count exceeding a first combination threshold concurrently with the second event count exceeding a second combination threshold. Other embodiments are described and claimed.
