Abstract: A processor includes a plurality of voltage droop detectors positioned at multiple points of a processor. The detectors monitor voltage levels and alert the processor if a droop event has been detected in real time. Multiple droops can be detected simultaneously, with each detected droop event generating an alert that is sent to a processor module, such as a clock control module, to act based on the detected droop. Each detector employs a ring oscillator that generates a periodic signal and a corresponding count based on that signal, where the frequency of the signal varies based on a voltage at the corresponding point being monitored.

Abstract: An apparatus includes a processor, a sleep state duration prediction module, and a system management unit. The sleep state duration prediction module is configured to predict a sleep state duration for component of the processing device. The system management unit is to transition the component into a sleep state selected from a plurality of sleep states based on a comparison of the predicted sleep state duration to at least one duration threshold. Each sleep state of the plurality of sleep states is a lower power state than a previous sleep state of the plurality of sleep states.
