• Technology Validation: NMP ST8 Dependable

Abstract—Current and future space-based processing applications are requiring, and will require, increasing amounts of onboard processing capability. One way to achieve a high level of processing capability is through the use of COTS (Commercial-Off-The-Shelf) high-performance processors. While state-of-the-art COTS processors are exhibiting adequate Total Integrated Dose (TID) performance to meet the requirements of the natural space radiation environment, Single Event Upsets (SEUs) caused by Galactic Cosmic Rays and Solar Protons will remain a problem. Traditional approaches to mitigate the SEU problem involve fixed redundancy schemes such as Self Checking Pairs (SCP) or Triple Modular Redundancy (TMR). While effective in mitigating the effects of SEUs, use of these techniques comes at a high price, 100
