Abstract
According to an aspect, there is provided an apparatus for power management of a system on a chip, SoC. The apparatus comprises means for performing the following. The apparatus maintains, in a memory, a knowledge-based system comprising a plurality of rules. Each rule maps a shift from a first to a second SoC state to a set of one or more sequential actions for activating a power tree configuration corresponding to said second SoC state. The apparatus receives a request for adjusting a current power tree configuration so as to match a target SoC state. The apparatus determines a set of one or more sequential actions for activating an optimal power tree configuration for the SoC based on the knowledge-based system using current and target SoC states as an input. Finally, the apparatus adjusts the current power tree configuration according to the set of one or more sequential actions.
