In this study, we present an energy-efficient FPGA design strategy specifically aimed at wearable devices using approximate computing techniques. Wearable devices, such as fitness trackers and health monitors, require prolonged battery life while maintaining reliable performance. Approximate computing offers a solution by allowing controlled inaccuracies in non-critical operations, significantly reducing power consumption. Our approach focuses on selectively applying approximations to arithmetic units and signal processing modules commonly used in wearable applications. Experimental results demonstrate a 30 % reduction in dynamic power and a 25 % decrease in leakage power. The impact on performance remains within an acceptable range, with a minor error margin of 3-5 %. Key applications such as heart rate monitoring, motion tracking, and step counting were assessed, demonstrating that this technique can extend battery life by 20 %, making it suitable for low-power, real-time monitoring scenarios. This design approach strikes a balance between efficiency and accuracy, providing a practical solution for power-constrained wearable technology. |
