Research on Time Performance Simulation and Analysis Technology of Aviation Complex Embedded System

嵌入式计算机作为嵌入式系统的核心成员,其时间性能对系统功能性能的综合表现起着关键的作用,但随着航空成品复杂度的不断增加,传统基于文件的系统研制手段正面临着验证耗时长、难以验证充分的挑战。为提高复杂嵌入式系统时间性能分析的准确性、提前发现设计中潜在的时序安排隐患,避免系统综合阶段由于系统时序缺陷导致的设计迭代,研究了针对航空复杂嵌入式系统的时间性能分析模型搭建和分析方法,并对时间性能分析仿真工具进行了二次开发,搭建了通用化的航空嵌入式系统时间性能仿真平台,实现了基于模型的标准化、可视化、图形化的时间性能分析。

As a core member of an embedded system, the embedded computer’s time performance plays a key role in the comprehensive performance of the system’s functional performance. However, as the complexity of aviation products continues to increase, traditional system development methods are facing the challenge for verification. In order to improve the accuracy of time performance analysis for the complex embedded system, find the potential hazards in the design of scheduling early, and avoid the system comprehensive stage design iteration caused by the time system defects, the methodology of the construction of the model and the analysis method of the time performance analysis for the airline complex embedded system is researched. This paper suggests a general time-performance simulation platform for the aviation embedded system. Therefore, with the secondary development of the time performance analysis and simulation tools, the standardized, visualized and graphical time performance analysis is carried out.
