Abstract

By developing Radiation Hardening by Software (RHBSW) techniques leveraged from the High Performance Computing community, the A-OPSS project seeks to deliver radiation tolerant, high performance System on a Chip (SoC) processors. This SoC architecture is uniquely suited to both handle high performance signal processing tasks, as well as autonomous agent processing. This allows situational awareness to be developed in-situ, resulting in a 10-100x decrease in processing latency, which directly translates into more science experiments conducted per day and a more thorough, timely analysis of captured data. This paper focuses on the second year’s efforts which revolve around developing a fault emulator for the embedded PowerPC within Xilinx V4FX devices, validating the RHBSW techniques developed in the prior year, and projecting performance results on a representative autonomous Hyperspectral application.
