Regulating the activity of a core

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 (S120): modifying the clock rate of the core (S130) by decreasing the ratio of active cycles of the clock; and running the core at the clock rate modified (S140) by decreasing the ratio of active cycles of the clock; when the monitored value reaches a second time the trigger value (S170): modifying the clock rate of the core (S180) by increasing the ratio of active cycles of the clock; and running the core at the clock rate (S190) modified by increasing the ratio of active cycles of the clock.
