    摘要： It is proposed a method for regulating the activity of a core running at a given clock rate. The method comprises: - monitoring (S100) a value of a parameter of the core, the parameter being a critical parameter for a safe operating of the core; - determining whether the monitored value reaches a trigger value; - when the monitored value reaches the trigger value (S 120): o modifying the clock rate of the core (S130) by decreasing the ratio of active cycles of the clock; and o running the core at the clock rate modified (S 140) by decreasing the ratio of active cycles of the clock; - when the monitored value reaches a second time the trigger value (S 170): o modifying the clock rate of the core (S180) by increasing the ratio of active cycles of the clock; and o running the core at the clock rate (S 190) modified by increasing the ratio of active cycles of the clock.
