Low-power design strategy for single-chip microcomputer system: Abstract The low-power design of embedded systems requires a comprehensive analysis of various factors and overall planning. At the beginning of the design, various factors are often mutually restricted and influenced. A measure to reduce system power consumption sometimes brings \"negative effects\" in other aspects. Therefore, reducing the overall power consumption of the system requires careful analysis and calculation. This article explains some issues that need to be considered when designing a low-power embedded system with a single-chip microcomputer as the core from the two aspects of hardware and application software design. Keywords Low-power design Hardware design Application software design Low-power mode In embedded applications, the power consumption of the system is increasingly valued by people, which is especially obvious for portable systems that require battery power. Reducing system power consumption and extending battery life means reducing the operating cost of the system. For embedded applications with single-chip microcomputers as the core, minimizing system power consumption needs to start from both software and hardware design. As more and more embedded applications use real-time operating systems, how to reduce system power consumption at the operating system level has also become a problem worthy of attention. Due to space limitations, this article only discusses hardware design and application software design.
