In an embodiment, a processor includes processing cores to execute instructions; and throttling logic. The throttling logic is to: determine an average capacitance score for execution events in a sliding window; perform frequency throttling when the average capacitance score exceeds a throttling threshold; determine a count of frequency throttling instances; and in response to a determination that the count of frequency throttling instances exceeds a maximum throttling value, increase the throttling threshold and concurrently reduce a baseline frequency. Other embodiments are described and claimed.

Adjusting a throttling threshold in a processor

In an embodiment, a processor includes processing engines to execute instructions and power limit logic. The power limit logic is to: in response to a plurality of power spikes, perform a number of soft throttling events and a number of hard throttling events in a first processing engine; determine a ratio of the soft throttling events to the hard throttling events; compare the determined ratio to a desired goal; and adjust one or more throttling parameters in response to a determination that the determined ratio does not match the desired goal. Other embodiments are described and claimed.
