<p>A method, apparatus, and computer implemented instructions in a data processing system for managing processor power usage. Current processor utilization is compared to current processor spaced to form a comparison. Current processor speed is decreased in response to current processor speed being greater then the current processor utilization. Current processor speed is increased in response to processor speed being less than the current processor utilization in the comparison. In this manner processor speed is adjusted to meet the processor utilization. In addition, power management may be based on particular programs executing on the data processing system. A program is identified in the data processing system to form an identified program. This identified program may be one that is being initialized for execution or currently executing. Power usage is set based on the identified program. User input may be used to select particular programs for power management.</p> |
