Methods and means of reliability increasing and information stability of the multiprocessor systems for objects of critical assignment

Reliability improvement of multiprocessor systems (MS) designed for controlling sophisticated objects, in particular those of critical purpose, is achieved in a variety of ways, which are discussed in this work, by introducing different types of redundancy, in particular temporal and hardware redundancies, and most often – by the fault-tolerant design of the system. The minimum number of additional processors required to increase the reliability (probability of operation without failure) of the system to the desired level is estimated.
