An FPGA-based framework for run-time injection and analysis of soft errors in microprocessors

摘要

State-of-the-art cyber-physical systems are increasingly deployed in harsh environments with non-negligible soft error rates, such as aviation or search-and-rescue missions. State-of-the-art nanoscale manufacturing technologies are more vulnerable to soft errors. In this paper, we present an FPGA-based framework for injecting soft errors into user-specified memory elements of an entire microprocessor (MIPS32) running application software. While the framework is applicable to arbitrary software, we demonstrate its usage by characterizing soft errors effects on several software filters used in aviation for probabilistic sensor data fusion.
