摘要
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 TMR architecture, designed under both spatial and implementation diversification premises. Moreover, since the strategy works on the device's bitstream domain, the basis for Virtex-4 FPGAs bitstream definition are also shown.
