Traditionally, the usage of widespread safety voted-groups architectures is a matter of redundancy, where hardware and software components are replicated which leads to drastically decreased system reliability; therefore necessity of functional diversity is become essential. Well known process of N-version programming minimizes the probability of producing similar erroneous results, but In this paper the combined soft-ware and hardware methods to achieve safety system requirements without enlarged implementation price is proposed. Avoidance of redundant complexity with limitation the number of system’s internal states is naturally led to functional diversity with re-sidual and common cause faults are decreased to achievable level.
