Methods and apparatus to manage power consumption of a system

A method to manage power consumption of a processor, comprising:

• altering the frequency of a clock signal using information in a data stream, wherein the processor is coupled to receive the clock signal and wherein altering the frequency of the clock signal alters power consumption of the processor;
• and
• processing at least a portion of the data stream using the processor.

A system, comprising;

• a processor coupled to receive a clock signal, the processor to process at least a portion of a video data stream;
• and
• control logic to determine display resolution using information in the video data stream and to alter the frequency of the clock signal based on the display resolution to alter power consumption of the processor.

A system, comprising;

• a processor coupled to receive a clock signal, the processor to process at least a portion of a data stream and wherein the processing speed of the processor is determined by the frequency of the clock signal;
• and
• control logic to determine the data rate of the data stream using information in the data stream and to alter the frequency of the clock signal based on the data rate of the data stream to alter power consumption of the processor.

A method, comprising:

• altering power consumption of a stream processing system based on information from a data stream to be processed by the stream processing system.
