摘要

在这篇文章中，我们提供了关于我们开发的用于小型卫星的基于软件的容错架构的实际可行性、有效性和验证的见解。我们利用线程级粗粒度锁步来促进前向纠错，并确保基于fpga的MPSoC的计算正确性。它可以使用标准的开源和FPGA设计工具来实现，只需要标准的COTS组件，并且与处理器架构和操作系统无关。

Software-Defined Dependable Computing for Spacecraft

In this contribution, we provide insights on the practical feasibility, effectiveness, and validation of a software-based fault-tolerance architecture we developed for use aboard small satellites. We exploit thread-level coarse-grain lockstep to facilitate forward-error-correction and assures computational correctness on an FPGA-based MPSoC. It can be implemented using standard open-source and FPGA design tools, requires only standard COTS components, and is processor architecture and operating system agnostic.
