    摘要: An integrated, on-chip thermal management system providing closed-loop temperature control of an IC device and methods of performing thermal management of an IC device. The thermal management system comprises a temperature detection element, a power modulation element, a control element, and a visibility element. The temperature detection element includes a temperature sensor for detecting die temperature. The power modulation element may reduce the power consumption of an IC device by directly lowering the power consumption of the IC device, by limiting the speed at which the IC device executes instructions, by limiting the number of instructions executed by the IC device, or by a combination of these techniques. The control element allows for control over the behavior of the thermal management system, and the visibility element allows external devices to monitor the status of the thermal management system.

    摘要: A method and apparatus for power throttling to manage the temperature of an IC. A temperature sensor is manufactured on the same die as the IC components. The temperature sensor generates an output in response to junction temperature of the IC components. A state machine is coupled to receive the output of the temperature sensor and to provide power reduction functions in response to the temperature sensor output exceeding a maximum thermal value. The maximum thermal value is less than the maximum allowable temperature of the IC corresponding to maximum power consumption. Thus, the invention reduces power consumption at a thermal value lower that a potentially catastrophic value rather than shutting down the IC when catastrophic failure is imminent.
