Power constraints play a critical role in embedded system design, especially for battery-powered or portable devices. Designers must optimize both hardware and software to minimize energy consumption without sacrificing performance. Techniques such as dynamic voltage scaling, power gating, and efficient coding help extend battery life and reduce heat generation. Component selection, such as low-power microcontrollers and sensors, is also essential. These considerations ensure that the system operates reliably within limited power budgets. Managing power effectively leads to longer device life and improved user satisfaction. Understanding these factors is essential for anyone pursuing an Embedded Systems Course.
