一种数据流驱动的计算通道容错方案.

When a single event upset occurred in the data flow - driven computation channel，it produces erro-neous results or even the computational channel will not function properly. For this reason，this study proposed a dual -mode redundant fault - tolerant scheme based on address rewinding technology，which used double computing channel comparison to detect whether the error occurs. The address rewinding technique was used to restore the address information and drive the original data to be recalculated. A specific optimized rewind on the correlation data stream calculations was also performed in the study. Based on the data stream driven operator，the scheme was implemented .The experimental results showed that the scheme achieved a reliability rate of over 99%，the area cost was only 76% of the three - mode redundancy，and the time overhead was up to 50% compared witli the dual - mode redundancy， indicating the scheme successfully achieved a balance bet"ween area and time consumption.
