Abstract

In this work, we propose a heterogeneous computing system which can seamlessly integrate with the COTS part and provide design hardening against radiation without modifying the inherent design of the COTS part. In Phase I, we worked on the base design of proposed heterogeneous computing system using a digital COTS part as circuit under test (CUT). A machine learning based intelligent mathematical model was designed to monitor and analyze radiation effects in COTS CUT. A selective redundancy-based fault tolerance model was designed to dynamically mitigate radiation effects. Finally, the individual modules, radiation monitor, fault tolerance, were integrated using a heterogeneous computing system. In Phase II, we will focus on the optimization of the proposed methodology by adjusting the design to achieve desired performance. We will expand the proposed system’s capability to address an analog and mixed signal CUT. Prominent analog COTS parts like analog-to-digital and digital-to-analog converters (ADC/DAC) will be used as CUT, and the proposed system and its modules will be tested and validated. The optimized system will be prototyped and tested with the chosen COTS CUT. Approved for Public Release | 22-MDA-11340 (16 Dec 22)
