Why may FPGAs be less susceptible than microprocessors to software common-cause failures?
Because field programmable gate arrays (FPGAs) are significantly simpler than microprocessors and link only the functions needed for a given application, the complexity of the resulting application system can be significantly less than that of a microprocessor-based system. Also, FPGAs have burned-in programmed logic that reacts to incoming information and do not rely on application software continuously running to process incoming information.
