Tutorial: System Level Power-Management Techniques

The Internet of Everything covers a wide spectrum of systems from sensors to servers, implemented in a wide range of semiconductor technologies. The underlying challenges of managing active and standby power and energy depend on the process technology and power sources and are covered as fundamentals in this tutorial. The requirement for a systems-level approach to power management and control in order to exploit dynamic and standby power and energy savings will then be explained. Practical examples will be covered for both high-end processing systems for cloud and hub applications, where power and thermal profile are most significant, as well as low-end processing in Wireless Sensor Nodes where energy saving is paramount.
