An Autonomous Fault-Tolerant System (AFTS) refers to a system that is able to configure its own resources in the presence of permanent defects and spontaneous random faults occurring in its silicon substrate in order to maintain its functionality. This work analyzes how AFTS could be built, specifically focusing on hardware platform dependant issues, and gives an overview of the state-of-the-art in...
This paper presents a new single event upset (SEU), multiple bit upset (MBU) and single hardware error (SHE) mitigation strategy to be used in Virtex-4 FPGAs. This strategy aims to increase not only the effectiveness of traditional triple module redundancy (TMR), but also the overall system availability. Frame readback with ECC detection and frame scrubbing are combined in a dynamically reconfigurable...
