Abstract:
A processor system includes first and second regulators for regulating an adjusted supply voltage. In one embodiment, the regulator system comprises a digital low-dropout (DLDO) control system comprising first and second regulators that generate a plurality of control signals to regulate an adjusted power supply voltage and that generate a charge when a droop level falls below a droop threshold value. The first regulator implements a first control loop and the second regulator implements a second and much faster acting control loop. A supply adjustment block with the two regulators and control loops are provided for each processor core allowing different cores to have different regulated supply levels all based on one common supply.
