Abstract: Methods and systems for operating a semiconductor device (e.g., a microprocessor) are described. The microprocessor is initially operated at a voltage and frequency that would be within operating limits at any device temperature. Using models that relate device temperature, operating limits and power consumption with voltage and frequency, the amount of supply voltage and a new operating frequency can be selected. The models are periodically consulted thereafter to continue adjusting the supply voltage and operating frequency, so that the microprocessor is caused to operate at very close to its capacity, in particular in those instances when, for example, processor-intensive instructions are being executed.

Abstract: In a computer-implemented method, an electronic communication from a first computing machine is received and includes a power value and one or more priority values. The power value represents a request for a power allotment expected to be used during a predetermined time and the priority values represent priorities of tasks expected to be executed during the predetermined time. A score for the request is calculated using a scoring function and the received priority values as inputs to the scoring function. The score is compared to one or more other scores respectively associated with requests for power allotments from other computing machines and previously calculated using the scoring function following receipt of one or more electronic communications each including a power value and one or more priority values. A top-ranked score is identified and an electronic communication is sent to the associated computing machine granting the requested power allotment.

Abstract: Systems and methods for control of integrated circuits comprising body-biasing systems. In accordance with a first embodiment of the present invention, a desirable power condition of a computer system comprising a microprocessor is determined. Body biasing voltage information corresponding to the power condition is accessed. A voltage supply coupled to a body terminal of the microprocessor is commanded to generate a voltage corresponding to the body biasing voltage information corresponding to the power condition.
