THE STRUCTURE OF THE COMPUTER SYSTEM IN THE RESIDUAL CLASSES

The subject of the article is formulation and solution inverse problem optimal redundancy in system residual classes (RNS) based on use dynamic programming method. this makes it possible to improve reliability operation computer systems components (CSC) RNS. purpose increase functioning CSC, which are built basis RNS, without reducing speed calculations, as well calculate compare reliability, terms probability failure-free operation, CSC RNS a tripled computing that operates positional binary number (PNS). Tasks: analyze influence used taking into account primary secondary redundancy; synthesize for l-byte bit grid passive fault tolerance method (constant structural redundancy); formulate solve method; check correctness results obtained, conditional amount equipment classes; evaluate efficiency using when building redundant relation PNS. Research methods: methods analysis synthesis systems, theory, coding theory theory. following obtained. paper shows PNS does not allow radical performance CSC. In regard, developed concept constructing Based this, formulated solved. Conclusions. As shown by calculations comparative analysis, provides higher than majority three-channel obtained research can be fault-tolerant structures
