SEU Reinforcement Method for Multicore Processors Based on Dual Core Lockstep
It is one of the main factors restricting the spatial application of commercial off-the-shelf(COTS)devices for the soft error represented by single event flipping;In order to meet the requirements of radiation protection for highly integrated satellite elec-tronic systems in space applications,a single event flip reinforcement method for general multi-core processor is proposed.Through the dual core and mutual inspection in software level,the reliability of COTS devices is fully improved without additional hardware o-verhead,with a good portability and strong engineering practical value;The software fault injection experiments are conducted to in-ject the error information at the key nodes during execution program,and verify the practicality of the dual core and mutual inspection method;The experimental results show that the dual core interlocking method can fully detect the single event flipping generated in the system,and meet the application of its ability to resist soft errors.
