摘要: Several concurrent error detection schemes suitable for a watch-dog processor were evaluated by fault injection. Soft errors induced into MC6809E microprocessor heavy-ion radiation from Californium-252 source. Recordings of behavior used to characterize the as well determine coverage and latency various schemes. The recordings input programs that simulate detected up 79% all within 85 bus cycles. Fifty-eight percent caused execution diverge permanently correct program. best 99% these errors. Eighteen affected only data, was at most 38%. >
