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...

Zusammenfassung: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.
