Implementation of the t/(n-1) decision-making algorithm by RTOS and FPGA tools

Abstract

The paper describes the combined implementation of the decision block in multiversion systems. The importance of fault-tolerant real-time control systems is proved. The authors describe an approach that makes it possible to increase the reliability parameters of such systems and to guarantee time delays. The approach means the presence of a watchdog timer and a redundant decision block implemented on the FPGA. The authors give an example of the main decision- making block implementation. It executed in a real-time operating system applying the Formula Node and Call Library Function tools in the LabView environment. С. An example of a t/(n-1) decision-making algorithm implemented as an extensible library written in the C language is considered. Also, the implementation of the t/(n-1) decision-making algorithm as a duplicate algorithm implemented on FPGA is considered. An example of software implementation of algorithms is given. The necessary tools are described.
