Abstract:

According to an aspect, power management of a multi-core processing system includes determining workload characteristics in the multi-core processing system. A power adjustment scenario is identified based on the workload characteristics. A predetermined actuation order for at least two power adjustment actuators is identified based on the power adjustment scenario. Based on the predetermined actuation order, it is determined whether there is an adequate adjustment capacity for a power adjustment action associated with one of the at least two power adjustment actuators. The power adjustment action is initiated based on the predetermined actuation order and determining that the adequate adjustment capacity is available.
