A CPU control method and apparatus for improving application processing speed and power consumption are provided. An embodiment of the invention provides a method by which a CPU control apparatus controls a CPU, where the CPU control method includes: (a) measuring a reaction time of a user terminal for a running application; (b) computing a first predictive reaction time by stepwise changing a CPU frequency if the reaction time exceeds a preset threshold; (c) computing a second predictive reaction time by stepwise changing a processing weight of the application if the first predictive reaction time exceeds the preset threshold; and (d) repeating said step (c) if the second predictive reaction time exceeds the preset threshold.

CPU control method and apparatus for improving application processing speed and power consumption

Disclosed are a terminal device and a method for controlling the terminal device that can reduce power consumption. The disclosed terminal device includes: a response time establisher unit which establishes a response time of an interactive application executed on the terminal device, with a frequency of a processor within the terminal device and a priority value of the interactive application as variables; a frequency determiner unit which determines the frequency of the processor based on a default priority value such that the response time does not exceed a preset response time threshold; a priority value determiner unit which determines the priority value based on the determined frequency such that the response time does not exceed the response time threshold; and an executor unit which runs the interactive application based on the determined frequency and the determined priority value.
