An Extensive Soft Error Reliability Analysis of a Real Autonomous Vehicle Software Stack

摘要

Automotive systems are integrating artificial intelligence and complex software stacks aiming to interpret the real world, make decisions, and perform actions without human input. The occurrence of soft errors in such systems can lead to wrong decisions, which might ultimately incur in life losses. This brief focuses on the soft error susceptibility assessment of a real automotive application running on top of unmodified Linux kernels, and considering two commercially available processors, and three cross-compilers. Results collected from more than 29 thousand simulation hours show that the occurrence of faults in critical functions may cause 2.16x more failures on the system.
