<p>Disclosed are a processor operating frequency control method and device, the method comprising: when an application program is running in the foreground, performing statistics on the running time lengths of a processor on different operating frequencies; when the application program initiates in the foreground at the present time, selecting, on the basis of the past running time lengths of the processor corresponding to the application program on different operating frequencies, the highest processor operating frequency required for the application program and treating said frequency as the operating frequency upper limit that the processor can reach during the application program running. The device comprises: a time length statistics module and a frequency control module. In the present invention, the processor function required during the time each application program runs in the foreground is studied and analyzed for statistics. When an application program is running in the foreground, the frequency of the processor is dynamically adjusted to be within an appropriate range, thereby ensuring the program application function and maximizing energy conservation.</p> |
