Abstract: An apparatus and method for efficiently managing power consumption of multiple partitions of an integrated circuit. A processing unit includes multiple partitions, each assigned to operation parameters of a respective power domain. Each of the partitions is assigned to operating parameters of a respective power domain. A power manager accesses a total power consumption budget for the multiple partitions and sends corresponding assigned power limits to the multiple partitions. A particular partition calculates a corresponding measurement of power consumption as a weighted sum of sampled signals, and performs steps to reduce power consumption when the particular partition determines the corresponding measurement of power consumption exceeds a corresponding assigned power limit. The power manager updates the assigned power limits within a first time interval. The multiple partitions calculate the power consumption measurements and perform power reduction steps within a second time interval less than the first time interval.
