Abstract
An information processing system includes an operation speed adjustable processor, and is adapted so that, with increase of operation speed of the processor, its performance is improved and power consumption is increased. The system comprises a scheduling unit for carrying out a processing to determine task of which processing should be executed at respective time points to shift control right to the task in accordance with the determination result, a power management unit periodically activated to carry out prediction of the power consumption of the processor and setting of operation frequency thereof, and a satisfaction degree evaluation unit activated in response to request from a scheduling module to evaluate the relationship between respective tasks and satisfactory services provided by them. Accordingly, it is possible to suppress operation frequency of the processor within the range that the satisfaction degree permits thus to carry out power saving.
