面向物联网应用的嵌入式软件设计与优化
摘 要
随着物联网技术的迅猛发展，嵌入式系统作为物联网终端设备的核心组成部分，其软件设计与优化成为提升系统性能、降低功耗及确保可靠性的关键。本研究旨在面向物联网应用，深入探讨嵌入式软件的设计与优化方法。通过分析物联网应用场景对嵌入式软件在实时性、安全性、低功耗等方面的需求，提出一种基于模型驱动的嵌入式软件开发框架，该框架融合了领域特定语言和自动代码生成技术，提高了软件开发效率并减少了人为错误。同时，针对资源受限的嵌入式环境，引入多目标优化算法对软件进行优化，在保证功能正确性的前提下，实现了任务调度、内存分配等多方面的性能提升。实验结果表明，采用所提出的框架和优化方法后，软件的响应时间缩短了约30%，功耗降低了25%左右，且系统的鲁棒性和可维护性显著增强。

Abstract
With the rapid development of the Internet of Things technology, embedded system, as the core component of the Internet of Things terminal equipment, and its software design and optimization has become the key to improve the system performance, reduce power consumption and ensure reliability. This study aims to deeply explore the design and optimization methods of embedded software for IoT applications. By analyzing the requirements of embedded software in real-time, security and low power consumption in the Internet of Things application scenarios, a model-driven embedded software development fr amework is proposed, which integrates domain-specific language and automatic code generation technology, improves the efficiency of software development and reduces human error. At the same time, for the resource-limited embedded environment, the multi-ob jective optimization algorithm is introduced to optimize the software, and on the premise of ensuring the correctness of the functions, the performance improvement of task scheduling and memory allocation is realized. The experimental results show that after adopting the proposed fr amework and optimization method, the response time of the software is shortened by about 30%, the power consumption is reduced by about 25%, and the robustness and maintainability of the system are significantly enhanced.
