摘　　要：SpaceWire总线是专为空间应用设计的一种高速的星载总线标准,是当前和未来的空间任务数据处理系统的基本架构。然而对与SpaceWire总线网络实时性性能的研究仍不完备,无法保证总线用于可靠传输实时性要求高的关键控制信息。故提出一种基于虫洞路由网络传输建模的SpaceWire总线网络实时性性能分析计算方法。分析和仿真结果为实时传输的SpaceWire总线网络的设计提供了理论依据。SpaceWire is a high-rate on-board bus standard designed specially for space application and the basic framework of current and future data-handling architecture. However, the research on the real-time transmission performance of SpaceWire network is still not enough, and this could hardly ensure the network to implement on-time delivery of critical messages. This paper proposes a method based on wormhole routing transmission model to calculate and analyze the real-time transmission performance of SpaceWire network. The analysis and simulation results could provide theoretical foundation and guidance for the design of SpaceWire network with high real-time transmission performance.
