MAXIMUM CURRENT LIMITING METHOD AND APPARATUS
The maximum current is limited in a multi-processor core system by monitoring the latest power consumption in the processor cores, in order to prevent a system shutdown as a result of an over-current event. If the sum of the latest power of the processor cores exceeds a threshold limit, a performanc...

| description | The maximum current is limited in a multi-processor core system by monitoring the latest power consumption in the processor cores, in order to prevent a system shutdown as a result of an over-current event. If the sum of the latest power of the processor cores exceeds a threshold limit, a performance state (P-state) limit is enforced in the processor cores. The P-state limit causes a P-state change to a lower frequency, voltage and thus a lower current.
Selon l'invention, le courant maximal est limité dans un système à multiples coeurs de processeur par surveillance de la puissance consommée la plus récente dans les coeurs de processeur, de façon à empêcher un arrêt du système suite à un évènement de surintensité. Si la somme de la puissance la plus récente des coeurs de processeur dépasse une limite seuil, une limite d'état de fonctionnement (état P) est appliquée dans les coeurs de processeur. La limite d'état P provoque un changement d'état P vers une plus basse fréquence, une plus faible tension et ainsi un plus faible courant. |
