Abstract

Component based software development (CBSD) has been established in the development of automotive real-time embedded applications at Bosch. CBSD together with software product line (SPL) practice has improved software reuse, productivity, quality and complexity management, by raising the level of abstraction for software constructions and by sharing services. Although CBSD has contributed to the aforementioned improvement in the software development practice, the existing Bosch component model often requires software developers to take a close look at the implementation including models (e.g., ASCET-MD ) and even complex source code to understand software behavior and dependencies when reusing and adapting software components. This hinders the realization of the full benefits of CBSD, as the available information on the component level does not sufficiently describe important aspects of software behavior. This paper presents the concepts and case studies of 'signal flows' and 'mode dependent signal flows', which provide crucial software behavior information for real time embedded systems at the component level.

基于组件的实时嵌入式系统软件行为描述

基于组件的软件开发(CBSD)已经在博世的汽车实时嵌入式应用开发中建立起来。CBSD与软件产品线(SPL)实践一起，通过提高软件构造的抽象层次和共享服务，改进了软件重用、生产力、质量和复杂性管理。尽管CBSD对前面提到的软件开发实践中的改进做出了贡献，但是现有的Bosch组件模型通常要求软件开发人员在重用和调整软件组件时仔细查看实现，包括模型(例如，ASCET-MD)，甚至复杂的源代码，以了解软件行为和依赖关系。这阻碍了实现CBSD的全部好处，因为组件级别上的可用信息不能充分描述软件行为的重要方面。本文介绍了“信号流”和“模式相关信号流”的概念和案例研究，它们为实时嵌入式系统在组件级别提供了关键的软件行为信息。
