Abstract: An apparatus and method is described herein for providing a dynamic pulse scheme for a voltage supply. A load (current) demand event of a processor is either predicted and/or detected. In response to the current demand event, such as a change in the current demand; a temporary, transient voltage pulse is generated by a voltage supply to compensate for the current transient demand. As result, dynamic voltage supply pulses generated based on the load current or the prediction of the load current demand increases performance, decreases power consumption, and saves expensive addition of compensation components, such as capacitors to a processor package.

Abstract: A power manager controls the supply voltage level at a load according to load current demand, and optionally the impedance of the power delivery path, by adjusting the supply voltage. The supply voltage may be reduced by determining a fixed load current that corresponds to a first operating frequency, determining a supply voltage that corresponds to the fixed load current, and then powering the load based on the supply voltage. Alternatively, the supply voltage may be increased along with increasing the operating frequency of the load while maintaining system power consumption within a predetermined limit.
