Abstract
This study discusses the power consumption analysis and evaluation of embedded system and low power design technology. First, the power composition of the embedded system is analyzed in detail, and the main source of power consumption is defined. Then, a variety of power consumption evaluation methods are proposed, and the power consumption evaluation tools and platforms are introduced to support accurate and effective power consumption measurement and evaluation. In terms of hardware design, this study focuses on low-power processor and memory, low-power power management technology, low-power I / O interface design, and low-power hardware circuit design. Through the selection and design of low power processor and the type and characteristic analysis of low power memory, it provides the direction for hardware design. At the same time, the dynamic power management (DPM) and advanced power management (APM) technology are studied to achieve more refined power management. In I / O interface design, the power consumption characteristics and the low power design method are proposed. Finally, the design principles of low power circuits, especially the partition / time-sharing power supply technology to reduce the overall power consumption. In software design, this study proposes software energy saving design strategy, interrupt drive technology, compilation optimization technology, and software and hardware collaborative optimization technology. Through the design and optimization of the software implementation method and algorithm, the power consumption of the software is effectively reduced. The introduction of interrupt drive technology improves the response efficiency and energy efficiency ratio of the system. The application of compilation and optimization technology further improves the efficiency of code execution and reduces the power consumption. Finally, the necessity of collaborative optimization of software and hardware is emphasized, and the design and implementation of collaborative optimization technology are discussed to realize the optimal configuration of hardware and software resources and reduce power consumption.
