Reducing the amount of power your embedded device is consuming is not trivial. With so many devices moving to battery operations today, maximizing battery life can be the difference between a happy, raving customer and an unhappy one that ruins your company's reputation. This post explores seven steps for optimizing your embedded systems' power consumption. You'll gain insights into the steps and techniques necessary along with receiving a few resources to help you on your journey.

Summary

This blog by Jacob Beningo presents seven practical steps to reduce power consumption in embedded devices, blending hardware and firmware techniques. Readers will learn how to profile energy use, apply MCU low-power modes, optimize RTOS and firmware behavior, and choose power-efficient components to extend battery life.

Key Takeaways

Measure energy consumption using appropriate tools (power analyzers, Coulomb counters) to find real system hotspots.
Implement MCU low-power modes and configure clocks and peripheral gating to minimize idle power.
Optimize firmware and RTOS behavior with techniques such as tickless idle, event-driven design, and reduced wake-ups.
Use DMA, efficient peripheral usage, and sensor duty-cycling to offload the CPU and lower active-time energy.
Select and configure PMICs, regulators, and low-power wireless/sensor components for overall system efficiency.
