Low-power design techniques play a vital role in improving the efficiency of battery-operated embedded devices by reducing energy consumption and extending battery life. Methods such as clock gating, dynamic voltage and frequency scaling (DVFS), and efficient power management algorithms help minimize unnecessary power usage. Selecting low-power components, optimizing firmware, and utilizing sleep or standby modes further enhance energy efficiency. These techniques not only ensure longer operational periods but also improve device reliability and reduce maintenance needs. Understanding and applying these strategies is crucial for professionals working in this field. Learn more with an embedded systems training institute.
