Abstract
An apparatus sets an operating voltage of a shared power rail in a multi-core electronic device. The apparatus includes a system-on-chip (SoC) having multiple cores with each core in the SoC configured to report an operating status. The apparatus includes an operating state aggregator configured to receive the operating status reported from each core in the SoC and to select the selected operating voltage based on the operating status from each core. A voltage regulator is in communication with the operating state aggregator and a power management integrated circuit (PMIC). The selected operating voltage is then programmed into the (PMIC) to control the shared power rail.
