I2BCFC: An Effective Intra-Inter Block Control Flow Checking Method Against Single Event Upsets

摘要

This study presents Intra-Inter Block Control Flow Checking method (I2BCFC) based on software instruction level redundancy for intra-inter block control flow errors detection. In utilizing electronic equipment, space applications designers have two options ahead: radiation-hardening or radiation-tolerant equipment and Commercial Off-The Shelf (COTS) equipment which COTS is the appropriate option due to some reasons like cost and accessibility in many applications. COTS equipment in applications like space missions do not have tolerance capability against some threats such as Single Event Upsets (SEU). Therefore, there should be considerations in resisting these equipment against possible threats. I2BCFC as a technique for COTS reliability increase, has the overhead of 29% in memory in relation to the without code redundancy and this rate has at least 11% improvement in memory overhead in comparison with the previous methods. I2BCFC method has the average performance overheard of 27% in comparison with the normal state of program that it is 5% better than the previous methods.
