  • Patent number: 7831842
    Abstract: 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 ?t. A temperature control unit estimates the temperature after the period ?t 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 ?t 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.

  • Publication number: 20090292404
    Abstract: A control execution unit (114) of a control stack (110) contained in a software stack causes a receiving unit (112) to receive the temperatures of a main processor and a graphic processor. When it is discriminated on the basis of those temperatures that a thermal error has occurred, the control execution unit (114) causes a class acquisition unit (116) to acquire the class of an active application. Moreover, the control execution unit (114) executes a hardware control operation to adjust the action of a hardware and a software control operation to change the action contents of the application, thereby to control the heat generation state of the hardware. When the software control operation is to be executed, a control method according to the combination of a portion, at which the thermal error has occurred, and the kind of the active application is acquired from a reaction table (118), thereby to control the software control operation by the control method acquired.

  • Patent number: 7520669
    Abstract: A temperature sensor measures a temperature of a certain location inside a processor. An overall heat amount measurement unit measures the overall amount of heat of the processor. 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.

  • Publication number: 20070198134
    Abstract: An instruction decoder identifies, for each instruction, an operational block involved in the execution of the instruction and an associated heat release coefficient. The instruction decoder stores identified information in a heat release coefficient profile. An instruction scheduler schedules the instructions in accordance with the dependence of the instructions on data. A heat release frequency adder cumulatively adds the heat release coefficient to the heat release frequency of the operational block held in the operational block heat release frequency register as the execution of the scheduled instructions proceeds. A heat release frequency subtractor subtracts from the heat release frequency of the operational blocks in the operational block heat release frequency register in accordance with heat discharge that occurs with time.

  • Publication number: 20070074216
    Abstract: This task management method includes dividing a unit time of processing into a reserved band for guaranteeing real-timeness and a non-reserved band not for guaranteeing real-timeness, and skipping a task to be executed in the non-reserved band as appropriate when processor throughput falls. That is, when the operating frequency of the processor is lowered in order to suppress heat generation, the real-timeness of tasks to be executed in the reserved band is guaranteed at the expense of processing the task to be executed in the non-reserved band in a best-efforts fashion.

  • Patent number: 7167778
    Abstract: A temperature predicting unit predicts the temperature of an electronic device after a predetermined period, and the speed of temperature variation from the operating state of the load. Based on the results of prediction by the temperature predicting unit, a selection unit instructs either one or both of a nozzle control unit and an electric fan control unit to exercise control. According to a control signal from the selection unit, the nozzle control unit transmits a control signal to a nozzle unit to drive a jet cooling apparatus. According to a control signal from the selection unit, the electric fan control unit transmits a control signal to an electric fan unit to drive an electric fan. The selection unit selects the electric fan when the predicted speed of temperature variation exceeds a predetermined threshold, and selects the jet cooling apparatus when the predetermined thresholds is not exceeded.
