Abstract: An input/output bus for analog sensors in an integrated circuit is described. In one example, a plurality of analog sensors generate an analog output in response to a respective event on the integrated circuit. A plurality of digitizers each coupled to an analog sensor generate a digital representation of the analog output of the respective sensor, and a communications bus coupled to the plurality of digitizers communicates the digital representations to an external device.

Abstract: For one disclosed embodiment, modulation circuitry may control power conversion circuitry to supply power for one or more load circuits. Voltage regulation control circuitry may control the modulation circuitry to regulate voltage supply from the power conversion circuitry. Current surge balance control circuitry may separately control the modulation circuitry to provide supply current steps by the power conversion circuitry to help cancel load current surges. Other embodiments are also disclosed.

Abstract: While firing a number of phases of a multi-phase switching voltage regulator in a sequence, a determination is made as to which one of the phases has the lowest phase current. Then, the next phase, to be fired in the sequence, is selected as the one that has been determined to have the lowest phase current. Other embodiments are also described and claimed.

Abstract: A method and apparatus for current detection for microelectronic devices using source-switched sensors. An embodiment of a current detector for a microelectronic device includes a first voltage sensor and a second voltage sensor. The first voltage sensor is to measure a first voltage of the microelectronic device during a first time period and a second voltage of the microelectronic device during a second time period. The second voltage sensor is to measure the second voltage during the first time period and the first voltage during the second time period. A voltage value is equal to the sum of the first voltage measured by the first sensor plus the first voltage measured by the second sensor, minus the sum of the second voltage measured by the first sensor plus the second voltage measured by the second sensor. Other embodiments are also described and claimed.

Abstract: A system is disclosed. The system includes a central processing unit (CPU) to operate in one or more low power sleep states, and a power converter. The power converter includes phase inductors; and one or more power switches to drive the phase inductors. The one or more power switches are deactivated during the CPU sleep state.

Abstract: A method and an apparatus to regulate voltage supply have been disclosed. In one embodiment, the apparatus includes a power converter block to generate an output voltage from an input voltage and a voltage regulator controller coupled to the power converter block to input at least one time-modulated signal to the power converter block, the at least one time-modulated signal having a duty cycle, the voltage regulator controller including a counter having an increment value substantially proportional to the input voltage, wherein the counter is used to adjust the duty cycle of the at least one time-modulated signal. Other embodiments have been claimed and described.

Abstract: In some embodiments, an error based supply regulation scheme is provided where error information from a cache is monitored, and the supply level supplying a CPU associated with the cache is controlled based on the error information. Other embodiments are disclosed herein.

Abstract: In some embodiments, a supply control system is provided that assesses degradation of a CPU core and increases a supply to the core based on the assessed degradation. Other embodiments may be disclosed herein.
