In one embodiment, a processor includes a plurality of intellectual property (IP) circuits, each to execute instructions and including a local control circuit to enable the IP circuit to operate at a level above a local current budget for the IP circuit, unless the processor is undergoing a global violation. The processor may further include a power controller coupled to the plurality of IP circuits. The power controller may include a control circuit to receive request information from the plurality of IP circuits and, based at least in part on the request information, determine that the processor is undergoing the global violation when a global current budget is exceeded. Other embodiments are described and claimed.

System, apparatus and method for globally aware reactive local power control in a processor

In an embodiment, a processor includes a power control unit and a plurality of components. A first component of the plurality of components is to receive a power input from a power supply device. The power control unit is to: determine a received voltage at a power input terminal of the first component; determine a voltage difference between the received voltage of the first component and a reliability goal voltage of the first component; determine a running average value based on the voltage difference; and adjust a supply voltage of the power supply device based on the running average value. Other embodiments are described and claimed.
