Abstract:
A computer program product includes a computer readable storage medium having program instructions embodied therewith, wherein the program instructions are executable by a processor to cause the processor to perform a method. The method comprises obtaining an activity level for each of a plurality of functions of an integrated circuit, wherein each function has a different physical location on the integrated circuit. The method further includes dynamically adjusting an amount of current supplied to the integrated circuit by each of a plurality of power stages of a DC voltage regulator to meet the current requirements of the plurality of functions and to control power losses between the power stages and the functions, wherein each power stage has a different physical location along a perimeter of the integrated circuit.
