Research on Low-Power Optimization Methods and Software-Hardware Co-design Strategies for Embedded Systems

As the clock frequency and integration density of embedded systems continue to rise, especially with the widespread use of mobile embedded devices such as smartphones and Personal Digital Assistants (PDAs), power consumption has become a critical challenge in system design. Besides, the slower slower advancement of battery technology compared to computational power makes system-level optimizations to reduce energy consumption essential for enhancing performance and increasing device longevity. Therefore, this paper explores methods for power consumption optimization in embedded systems, examining the potential for low-power solutions via the collaboration of hardware and software design. By reviewing recent research and investigating the findings of Tiwari et al., which involved simulations and typical embedded system setups, this study offers a comprehensive analysis of how to optimize power consumption from multiple angles. The results demonstrate that software-level optimizations, such as algorithm scheduling and instruction optimization, can greatly reduce system power usage. Furthermore, software-hardware co-design is identified as the key direction for the future development of low-power embedded systems, enabling high energy efficiency without compromising performance.
