Space processor radiation mitigation and validation techniques for an 1,800 MIPS processor board

The latest commercial computing performance has been unavailable to the space community because of radiation reliability issues and the time and resources required to bring a radiation hardened version to market. This paper discusses computing performance, radiation mitigation, characterization and testing of a single board computer for space based on the latest IBM 750FX SO1 processor. The architecture, design, error mitigation techniques and radiation testing and evaluation of the design's performance are presented.
