摘要

本文将描述将基于航空IMA概念的软件时空划分(TSP)整合到航天器航空电子系统架构中的好处，以管理机载软件中实现的任务功能的增长。本文讨论了如何使用TSP来安全地集成不同关键性和安全性分类的应用程序，以及如何支持增量验证来控制软件修改对系统的影响。

Time and Space Partitioning in Spacecraft Avionics

This paper will describe the benefits of incorporating software Time and Space Partitioning (TSP), based upon the aeronautic IMA concept, into the spacecraft avionics architecture to manage the growth of mission functions implemented in the on-board software. The paper addresses how TSP can be used to safely integrate applications of different criticality and security classifications, and how incremental validation is supported to control the impact of software modifications to the system.
