Systems, methods and computer-readable mediums may be used in portable computing devices (PCDs) for dynamically allocating system resources in a way that prevents or lessens degradation of power and performance KPIs while also avoiding temperature increases in the PCD that can create unpleasant user experiences. A smart resource allocation framework (SRAF) is triggered when a call is received or placed. Once triggered, the SRAF framework monitors a preselected set of state conditions to determine whether or not to place the wireless modem in a modem power-performance (Mod. Pow.-Perf) mode. If it determines that modem is to be placed in the Mod. Pow.-Perf. mode, a Mod. Pow.-Perf. process is performed dynamically allocates system resources and preferably also triggers a thermal framework that performs power reduction in one or more non-modem processing cores.

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.
