| Abstract: | Fault localization imprecision is one critical problem to traditional dual modular redundancy fault tolerant computer. In this paper a highly-available arbitration subsystem is developed to solve this problem. The arbitration subsystem uses TMR as its system fault tolerant architecture, three different serial buses as its internal redundant communication bus, also uses SOC chip and CPLD technique to improve its reliability, and uses hot swap technique to improve its availability. |
