Abstract
A system for dynamic integrated circuit power distribution and control is disclosed. The system includes an external power consumption target generator configured to generate a power dissipation target for one or more integrated circuits. The system also includes a first integrated circuit that includes an IC power control unit coupled to the external power consumption target generator. The first integrated circuit also includes a first plurality of functional units, each functional unit of the first plurality including a unit power level control and a first power control grid coupling the IC power control unit to one or more of the first plurality of functional units. The IC power control unit is configured to generate a mode control signal which places at least one of plurality of functional units into a first mode of operation based upon the power consumption target.
