Abstract

For single event effect(SEE)of space radiation environment,a multi-level fault tolerant mechanism based on FPGA,which has greatly improved system's ability of resisting single event upset(SEU) was implemented.In addition,a SEL resisting protection circuit was designed with both chip-level and board-level's detections.With great reliability enhancement,it has been verified on space information processing platform prototype system.
