METHOD AND APPARATUS FOR HYBRID CHIP-LEVEL VOLTAGE SCALING

摘要

Various aspects of a power management approach for a system-on-a-chip (SoC) is disclosed herein. In one aspect, the approach includes implementing a power profile for supplying power to a plurality of subsystems on a shared power bus in the SoC. The power profile includes at least one adjustable parameter for controlling the supplied power during an active use state. The approach further includes detecting a power profile change trigger; modifying the power profile based on the power profile change trigger; and adjusting the supplied power during the active use state based on the modified power profile to maintain a predetermined supplied power level

1. A method for power management of a system-on-a-chip (SoC), comprising:
implementing a power profile for supplying power to a plurality of subsystems on a shared power bus, wherein the power profile comprises at least one adjustable parameter for controlling the supplied power during an active use state; detecting a power profile change trigger; modifying the power profile based on the power profile change trigger; and adjusting the supplied power during the active use state based on the modified power profile to maintain a predetermined supplied power level.
