Abstract:

With the development of integrated circuits, the transistor dimensions are reducing and the density is increasing, and ICs depend on work environment servers, so the possibility of soft error occuring becomes more often, which has important effect on the reliability of chips. Multicore microprocessors have become the mainstream over the past few yesrs, the redundant resources in the multicore microprocessors provide a redundant resource to enhance the reliability. A soft scrub method for multicore processors is proposed to tolerate soft errors. The experimental results demonstrate that this technique can greatly increase the reliability of the I/O systems.
