    摘要： Systems and methods for positioning thermal sensors within an integrated circuit in a manner that provides useful thermal measurements corresponding to different parts of the integrated circuit. In one embodiment, an integrated circuit includes multiple, duplicate functional blocks. A separate thermal sensor is coupled to each of the duplicate functional blocks, preferably in the same relative location on each of the duplicate functional blocks, and preferably at a hotspot. One embodiment also includes thermal sensors on one or more functional blocks of other types in the integrated circuit. One embodiment includes a thermal sensor positioned at a cool spot, such as at the edge of the integrated circuit chip. Each of the thermal sensors may have ports to enable power and ground connections or data connections between the sensors and external components or devices.

    摘要： 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.

    摘要： 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.

    摘要： 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. A hot spot detector detects an operational block with its heat release frequency, held in the operational block heat release frequency register, exceeding a predetermined threshold value as a hot spot. The instruction scheduler delays the execution of the instruction involving for its execution the operational block identified as a hot spot.

    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.
