Abstract: Techniques and mechanisms for determining operation a processor core which is in a common power delivery domain with one or more other processor cores. In an embodiment, an execution of instructions by a first core of a processor module is selectively throttled based on the detection of a single violation condition. The throttling is performed while the cores of the processor module are each maintained in a current power state. The single violation condition comprises a violation of a test criteria by the first core, while the one or more other cores of the module each satisfy the test criteria. In the case of a multiple violation condition, each core of the processor module is transitioned from one power state to another power state. In another embodiment, the test criteria includes or is otherwise based on a threshold level of a dynamic capacitance for a given core.
