Architecture Exploration for High-Integrated and Low-Cost Avionic Systems

现代航空电子系统是由异构分布式嵌入式处理器网络组成的软件密集型系统。这些安全关键系统必须表现出一系列的质量属性，其中最重要的是系统的安全性，可靠性和容错性。开发现代航空电子系统的组织面临着许多挑战。其中之一是需要选择和利用正确的基础设施技术来设计满足多个客户需求的产品线。此外，经济问题也在不断推动变革。空间、重量和功率（SWaP）考虑在航空工业的当前状态中变得越来越重要。 自21世纪初以来，一种名为IMA（集成模块化航空电子设备）的新体系结构已经出现，该体系结构通过将多个应用程序组合在单个计算机硬件单元内，有望显着提高安全关键方面，同时减少新航空电子系统的SWaP占用空间。

Modern avionics systems are software-intensive systems composed of a network of heterogeneous distributed embedded processors. These safety-critical systems must exhibit a series of quality attributes, among the most important being the system safety, reliability and fault-tolerance. Organizations developing modern avionic systems face numerous challenges. Among them is the need to choose and exploit the right infrastructure technologies to architect product lines addressing the requirements of multiple customers. Also, economic concerns are constantly pushing for changes. Space, weight and power (SWaP) considerations are gaining importance in the current state of the aviation industry. Since the early 2000's, a new architecture named IMA (Integrated Modular Avionics) has emerged that promises to significantly increase safety-critical aspects while reducing the SWaP footprint of new avionics systems by combining several applications within a single computer hardware unit.
