Abstract
A system and method of real-time power management for use in computer systems. The system utilization is assessed by a North bridge, and a result is transferred to a South bridge. Thereafter, through transmitting sideband signals to a voltage controller and a frequency controller by sideband pins, the North Bridge provides faster and more efficient power management performance than the system management bus (SMBUS).
