Abstract. Two main methods for data diagnosis, which are presented in the residue number system (RNS) are considered in the paper. It is shown that the main problem of these methods is the considerable time of data diagnosis in RNS. The proposed method makes it possible to reduce the errors diagnosis time for the data presented in the RNS, which increases the efficiency of the diagnosis. The use of the proposed method of operational data diagnosis increases the overall effectiveness and expediency of its application in computer systems of non-position code structures in RNS.

Keywords: residue number system, data control, speed of data diagnostics, position-independent code structure, alternative aggregate of the number.
