Abstract
A power control system provides multiple supply voltages that are guaranteed not to violate boundary conditions regardless of the timing of voltage change commands. A first voltage (Vlogic in the embodiments described herein) is controlled conventionally, and a second voltage (Vmemory) is either selected, or generated by adding a selected offset to the first voltage. Both the size of the offset, and the absolute value of the second voltage, are constrained at all times, by constraint values specific to the current voltage zone. The invention ensures a smooth transition between different voltage operating points, and ensures that the trajectory of change between specified operating points remains within predefined boundaries.
