Abstract: A method for determining power dissipation within a computer system is disclosed. A circuit block may receive a regulated voltage level on a power supply signal generated by a voltage regulator circuit. A power control circuit may measure a current drawn by the circuit block, and determine a real-time voltage level for the power supply signal using the current and based on a slope value and a zero-load voltage level. Additionally, power control circuit may determine a power dissipation for the circuit block using the current and the real-time voltage level, and adjust an operation parameter of the circuit block based on the power dissipation.

Abstract: A method for adjusting operation parameters of a computer system based on power consumption of the computer system is disclosed. During a power state transition of the computer system, a voltage level of a power supply signal may be sampled at a plurality of time points to generate a multiple voltage level samples. A voltage level of a selected one of the multiple voltage level samples may be adjusted using a particular coefficient of multiple coefficients to generate an updated voltage level sample. A power consumption of the computer system may be determined using the updated voltage level sample, and based on the power consumption, at least one operation parameter of the computer system may be adjusted.

Abstract: A method and apparatus for calibrating a temperature sensor is disclosed. In one embodiment, a method comprises generating first and second digital values based respectively on first and second voltages applied to a portion of a temperature sensor circuit. An arithmetic circuit may derive the value of the second voltage based on the first and second digital values. The method further comprises determining an initial value of a constant based on values of the first and second voltages, and determining a final value of the constant based on the initial voltage and at least one voltage offset. The constant may then be used in determining temperature readings for the temperature sensor.

Abstract: A system that generates a click signal includes a first digitally controlled oscillator (DCO) having a first fundamental frequency, and a second DCO having a second fundamental frequency. The system also includes a Muller C-element, which combines outputs of the first and second DCOs to produce the clock signal, which feeds back into the first and second DCOs. During a calibration operation, while the second DCO is set to a frequency larger than the target frequency, the system adjusts the first DCO with reference to a first feedback loop, which includes the first DCO, so that the clock signal matches the target frequency, and while the first DCO is set to the adjusted first fundamental frequency plus a frequency offset, the system adjusts the second DCO with reference to a second feedback loop, which includes the second DCO, so that the clock signal matches the target frequency.

Abstract: A power management controller is disclosed. Broadly speaking, the controller may, in response to receiving a timing signal, monitor a temperature of an integrated circuit including multiple processor clusters. The controller may generate a comparison of the temperature and a threshold value, and in response to a determination that the comparison indicates that the temperature is less than the threshold value, transition a particular processor cluster to a new power state.
