GPU4S：空间嵌入式GPU--最新项目更新
GPU4S: Embedded GPUs in Space -- Latest Project Updates
摘要：
随着汽车和航空电子等其他安全关键行业的发展趋势，空间领域对机载计算性能的需求正在增加。这种性能需求的提高来自航天器的控制和有效载荷部分，并要求先进的电子系统能够在恶劣的空间环境限制下提供高计算能力。在非技术方面，出于战略原因，必须在所使用的计算技术上获得欧洲的独立性。在这个项目中，我们研究了嵌入式GPU在太空中的适用性，这些GPU在基于竞争性欧洲技术的消费者市场中的扩散，显示出其性能/功耗比的显着提高。为此，我们对现有的空间应用领域进行了分析，以确定哪些软件领域可以从它们的使用中受益。此外，我们调查了嵌入式GPU领域，以评估嵌入式GPU是否可以提供所需的计算能力，并确定在太空中采用时需要解决的挑战。在本文中，我们描述了该项目所遵循的步骤，以及从我们的分析到目前为止，在该项目中所获得的结果的总结。
英文摘要：
Following the trend of other safety-critical industries like automotive and avionics, the space domain is witnessing an increase in the on-board computing performance demands. This raise in performance needs comes from both control and payload parts of the spacecraft and calls for advanced electronics systems able to provide high computational power under the constraints of the harsh space environment. On the non-technical side, for strategic reasons it is mandatory to get European independence on the used computing technology. In this project, we study the applicability of embedded GPUs in space, which have shown a dramatic improvement of their performance per-watt ratio coming from their proliferation in consumer markets based on competitive European technology. To that end, we perform an analysis of the existing space application domains to identify which software domains can benefit from their use. Moreover, we survey the embedded GPU domain in order to assess whether embedded GPUs can provide the required computational power and identify the challenges which need to be addressed for their adoption in space. In this paper, we describe the steps followed in the project, as well as a summary of results obtained from our analyses so far in the project.
