ABSTRACT:
An apparatus and method controlling power consumption in portable personal computers by dynamically allocating power to the system logic. Expected total power consumption is calculated and compared to an optimum power efficiency value. The expected power consumption values for each execution unit are stored in a look-up table in actual or compressed form. If the expected total power consumption value exceeds the power efficiency value, selected execution units are made inactive. Conversely, if the power efficiency value exceeds the expected total power consumption value, execution unit functions are added in order to maintain a level current demand on the battery.
