摘要

在这篇正在进行的论文中,我们提出了为科学卫星单处理器仪器设计本质可重构软件的第一步。在论述了可重构空间领域的具体规范之后,我们认为最合适的可重构级别是应用程序的重载任务和功能。动态到半动态的重新配置将满足大多数常见需求。我们指出,星载系统实时嵌入式软件的重构依赖于本质上可重构的软件设计和定义良好的地面段操作。一种很有前途的技术似乎是将软件的可重构部分设计为一组代理可访问的对象。我们提出了为法国天体物理卫星Corot设计这种软件的第一步。

The Corot instruments software: towards intrinsically reconfigurable real-time embedded processing software in space-borne instruments
In this work-in-progress paper we present the first step on the first attempt to design intrinsically reconfigurable software for single-processor instruments of scientific satellites. After disserting on the specifications particular of the space field for the reconfiguration, we argue that the most suitable reconfigurability level is overloading tasks and functions of the application. Dynamic to semi-dynamic reconfiguration will fulfill most of the common needs. We state that the reconfiguration of real-time embedded software for space-borne systems relies on an intrinsically reconfigurable software design and well-defined ground segment operations. A promising technique seems to be to design the reconfigurable parts of the software as a set of proxy-accessible objects. We present the first step in designing such software for the French astrophysical satellite Corot.
