抄録(英) | As the size of integrated circuit has reached the nanoscale, embedded memories are more sensitive to single event upset (SEU), because of their low threshold voltage. In particular field-programmable gate arrays (FPGAs), which contain large amounts of configuration memories to implement customer circuits, are more likely to suffer from soft errors caused by SEU. In this research, we first develop a Hamming code based error detect and correct (EDC) circuit that can prevent the configuration memory of a reconfigurable device from SEU. We then employ a novel reconfigurable logic element, namely COGRE, which will use much less configuration memory than the conventional FPGA 4-, 5- or 6-LUTs (lookup tables). Evaluation revealed that compared to the 6-LUT FPGAs with triple modular redundancy (TMR) configuration memory blocks, the 5- and 6-input proposed architecture save about 75.44 and 74.29% memories on average, respectively. And the dependability of proposed architecture is about 10 times better than the LUT with TMR architecture on average. |
