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.

摘要： A method of dynamically adjusting the power consumption of a circuit block within an integrated circuit includes the step of incrementing a count total maintained by a counter on the occurrence of a first type of trigger event. The occurrence of a predetermined event is detected when the count total maintained by the counter equals, or transcends, a predetermined threshold value. The predetermined event provides a speculative indication of a future state of activity of the circuit block by reason of a predicted proximity of the predetermined event to the future state of activity of the circuit block. The power consumption of the circuit block is adjusted in response to the occurrence of the predetermined event.

摘要： A power control circuit and corresponding technique for reducing power consumption by an electronic device and thereby increasing performance. The power control circuit comprises a controller, a clock generation circuit and a power supply circuit. The controller detects whether a condition exists to scale the voltage and frequency of the electronic device and in response, signals the clock generation circuit to perform frequency scaling on the electronic device and the power supply circuit to perform voltage scaling on the electronic device. The condition may include a situation where the temperature of the electronic device is detected to have exceeded a thermal band. The condition may also include a situation where the electronic device is detected to be idle for a selected percentage of its run time.

摘要： The operating voltage of an integrated circuit (e.g., a processor) is changed in response to one or more conditions (e.g., a laptop computer is connected to an AC power source). Both the operating frequency and the operating voltage of the integrated circuit are changed. The voltage regulator providing the operating voltage to the integrated circuit is caused to transition between voltage levels using one or more intermediate steps. The integrated circuit continues to operate in the normal manner both at the new voltage and throughout the voltage transition.

摘要： In one embodiment, the present invention includes a processor having a core with decode logic to decode an instruction prescribing an identification of a location to be monitored and a timer value, and a timer coupled to the decode logic to perform a count with respect to the timer value. The processor may further include a power management unit coupled to the core to determine a type of a low power state based at least in part on the timer value and cause the processor to enter the low power state responsive to the determination. Other embodiments are described and claimed.
