Power Management Techniques for Real-Time Embedded Systems
The paper begins with introductory material on the need for power management in embedded systems, along with definitions of some common power consumption terms and principles. Next comes a description of common power management techniques that are used in embedded systems, along with a discussion of some of the challenges to utilizing these techniques in real-time systems. The last half of the paper is dedicated to a demonstration of how a subset of the techniques have been incorporated into a real-time operating system (RTOS) for digital signal processors (DSPs), in such a way that application developers can pick and choose the appropriate techniques to meet their application requirements. The paper concludes with a brief description of supplementary tooling for measuring power consumption at runtime, which enables a new application development paradigm, that includes measurement and tuning of an application.s power consumption.
