Abstract
With the rapid development of the Internet of Things, wearable devices and mobile computing and other fields, embedded systems are increasingly widely used in various intelligent terminals, and low power consumption has become a key factor in their design. This study aims to explore effective low power design strategies to meet the requirements of embedded system for long time stable operation and extremely low energy consumption. For this purpose, the author selects hardware and software optimization from the hardware architecture and optimizes the circuit design to reduce static power consumption; adopts efficient power management algorithm and task scheduling strategy to reduce dynamic power consumption. By constructing simulation experiments with test models under various typical application scenarios, the results show that the proposed low-power design strategy can significantly reduce the overall power consumption of the system, and the average power consumption can be reduced by more than 35% without affecting the performance.
