An overview of power management techniques
In this section, we will explore the world of power management techniques, a crucial aspect of embedded systems design. As our devices become more advanced and our expectations for battery life increase, understanding how to manage power effectively is more important than ever. Let’s dive into the various power management techniques and how they are implemented, taking a look at some case studies to see these techniques in action.
Power management in embedded systems involves a combination of hardware and software strategies designed to reduce energy consumption. This is particularly important for battery-powered devices, where efficient power usage can significantly extend battery life. The main techniques we’ll cover include Dynamic Voltage and Frequency Scaling (DVFS), clock gating, power gating, and utilizing low-power modes.
Let’s start with DVFS.
