Hyperspectral images can comprise hundreds of spectral bands, which means that they can represent a large volume of data difficult to manage with the available on-board resources. Lossless compression solutions are interesting for reducing the amount of information stored or transmitted while preserving it at the same time. The Hyperspectral Lossless Compressor for space applications (SHyLoC), which is part of the European Space Agency (ESA) IP core’s library, has been demonstrated to meet the requirements of space missions in terms of compression efficiency, low complexity and high throughput. Currently, there is a trend to use Commercial Off-The-Shelf (COTS) on-board electronic devices on small satellites. Moreover, commercial Field-Programmable Gate Arrays (FPGAs) have been used in a number of them. Hence, a reliability analysis is required to ensure the robustness of the applications to Single Event Upsets (SEUs) in the configuration memory. In this work, we present a reliability analysis of this hyperspectral image compression module as a first step towards the development of ad-hoc fault-tolerant protection techniques for the SHyLoC IP core. The reliability analysis is performed using a fault-injection-based experimental set-up in which a hardware implementation of the Consultative Committee for Space Data Systems (CCSDS) 123.0-B-1 lossless compression standard is tested against configuration memory errors in a Xilinx Zynq XC7Z020 System-on-Chip. The results obtained for unhardened and redundancy-based protected versions of the module are put into perspective in terms of area/power consumption and availability/protection coverage gained to provide insight into the development of more efficient knowledge-based protection schemes.

SHyLoC CCSDS123 IP内核使用COTS FPGA进行无损高光谱图像压缩的可靠性分析

高光谱图像可以包含数百个光谱带，这意味着它们可以代表大量数据，这些数据很难用可用的机载资源进行管理。无损压缩解决方案对于减少存储或传输的信息量，同时又保留信息量是很有趣的。作为欧洲航天局（ESA）IP核心库的一部分，用于太空应用的高光谱无损压缩机（SHyLoC）已被证明可以满足太空任务在压缩效率，低复杂度和高吞吐量方面的要求。当前，有一种趋势是在小型卫星上使用商用现货（COTS）车载电子设备。此外，商业现场可编程门阵列（FPGA）已被用于许多领域。因此，需要进行可靠性分析，以确保应用程序对配置存储器中的单事件翻转（SEU）的鲁棒性。在这项工作中，我们将对此高光谱图像压缩模块进行可靠性分析，作为朝着SHyLoC IP核的临时容错保护技术发展的第一步。使用基于故障注入的实验设置进行可靠性分析，其中针对Xilinx Zynq中的配置存储错误测试了空间数据系统咨询委员会（CCSDS）123.0-B-1无损压缩标准的硬件实现XC7Z020片上系统。
