US Patent 7817488 Load balancing by using clock gears

An electronic device is capable of monitoring internal components to predict changes in processing power needs. When a prediction is made, a clock control circuit can be instructed to increase the clock signal frequency in response to a predicted increase in processing power needs, or decrease the clock signal frequency in response to a predicted decrease in processing power needs. The control circuit can further balance other clock signal frequencies in order to satisfy constraints such as a power supply constraint.
