A temperature estimation unit estimates the temperatures of a plurality of hot spots occurring in the processor based on the temperature of the certain location detected by the temperature sensor, and determines the maximum temperature of the processor. The temperature estimation unit switches between maximum load temperature estimation coefficients and individual load temperature estimation coefficients stored in a storing unit for reference, depending on the overall amount of heat of the processor, and applies them to a temperature estimation function(s) for converting the sensor temperature into the temperatures of the hot spots. An operating frequency control unit exercises control for lowering the operating frequency of the processor when the maximum temperature of the processor estimated by the temperature estimation unit exceeds a predetermined limit temperature.

摘要： A heat generation amount estimation unit acquires the number of sub processors currently in operation, acquires the current operating frequency, and estimates the amount of heat generation after a period Δt. A temperature control unit estimates the temperature after the period Δt based on the current temperature input from a temperature sensor and the amount of heat generation estimated, and compares it with a predetermined threshold temperature. If the predetermined threshold temperature is reached, the temperature control unit acquires the number of sub processors available in parallel after the period Δt from a task management unit, and consults a performance table to determine which operation point to shift to. A sub processor control unit and a frequency control unit switch to the number of sub processors in operation and the operating frequency accordingly. The performance table lists possible operation points in order of performance.
