Methodological approach to recovery correct functioning of embedded systems at the level of programmable element base

Abstract

The article proposes a methodical approach to restoring the proper functioning of specialized microprocessor control systems at the level of the programmable element base. This approach includes two stages. At the first stage, the main task of technical diagnostics is solved, namely the recognition of the state of a specialized microprocessor system, which includes: assessment of the technical state, forecasting, detection and localization of malfunctions. This task is solved by detecting errors in the operation of a specialized microprocessor control system, which are caused by the failure and failure of digital devices, errors in software, or other reasons, using existing control methods, as well as localization of malfunctions of a specialized microprocessor control system, using methods of test and functional diagnostics digital devices that are part of the system under consideration. At the second stage, the correct functioning of the specialized microprocessor control system is restored by reconfiguring its internal structure at the level of logical elements. At the same time, the reconfiguration of the internal structure is based on the position of the prescriptive theory, which considers the issue of purposeful management of objects of various nature, which are in a state of "conflict" with other objects. The implementation of the proposed approach in the future can be the basis for the design of active fault-tolerant systems that will be able to counteract failures a hardware and software nature as a result of internal or external adverse actions.
