Methods to provide fail-safety of computational systems intended to solve the problems of digital signal processing

The analysis of the basic methods to provide fail-safety of computational systems oriented to solve problems of digital signal processing, is carried out. Possibilities to apply hardware, time and information redundancies in the systems of digital processing the real time signals, are considered. An example to apply the analysed methods for the fail-safety increase in the digital computational system under analysis intended for the signal processing and controlling the Fourier transform spectrometer of the high resolution, is presented.
