Hybrid power management approach

摘要

Methods and apparatus to provide a hybrid power management approach are described. Some embodiments redefine the interface to Power Control Unit (PCU) allowing a hybrid implementation where software running on CPU (Central Processing Unit, also referred to herein interchangeably as “processor”) cores performs more of the work for power management, enabling the PCU to remain as a simple or regular microcontroller. Other embodiments are also disclosed and claimed.
