dc.description.abstract	Difference equation methods are used to develop redundant (n-version) programs required for high reliability computing systems. The n-version programs are developed by exploiting the iterative nature of real time software. The difference equation based programs are then combined with standard programs in a triple modular redundancy (TMR) hardware system by staggering the inputs to two of the modules in a TMR type system. The staggering of the inputs simulate the effect of using six different, but functionally identical program versions, within the system. Test results indicate that a high degree of software redundancy is achieved in the described system.	en
