L41: Power in electronics systems

Welcome to Lecture 41 of the course “Embedded C Programming” by Prof. Nitin Chandrachoodan.

Video Overview
This lecture examines power considerations in embedded systems, focusing on battery life and heat management. Learn about dynamic power (switching-related) and static power (leakage), and how they impact overall energy consumption. We analyze component-level power usage across the CPU, I/O, memory, peripherals, and display. Explore power-saving modes such as active, idle, and low-power sleep, along with duty cycle optimization strategies. The lecture also covers methods to estimate battery life and presents a worked example calculating average power during active and sleep cycles, integrating hardware and software approaches for efficient low-power design.
