Ivan Berdyshev, a graduate student of the Department “Automation and Telemechanics”, said that redundancy had its pros and cons. Positive was the high reliability of such system. The negative was redundancy, that is, high costs. For example, an increase in size, weight, energy consumption, a possible performance reduction and other indicators. In space, reliable solutions were required; redundancy was used, while there were limitations in size and weight. That is why we had to find a balance between reliability and redundancy. It was not always advisable to increase redundancy, so there was a need to find optimal solutions.
The main idea is to optimally redistribute tasks between subsystems. All these methods can be applied in various elements of devices, where, for example, triggers are reserved. Some parts that are most susceptible to failures may be selectively reserved.
The scientific supervisor of the researchers, Sergey Tyurin, professor of the Department “Automation and Telemechanics”, said that their work could be useful in designing electronic devices from the point of view of reliability. The development could be used for optimal design solutions when creating modern digital devices. In particular, they were considering the possibility of using these solutions in programmable logic integrated circuits.
Now, scientists are working on increasing the fault tolerance of integrated circuits using flexible redundancy methods, as well as transistor redundancy. This will increase the competitiveness of domestic electronics.
