METHOD FOR INCREASING MICROCOMPUTER RELIABILITY

摘要

FIELD: information technology.;SUBSTANCE: method allows directly in the microcomputer operational mode in parallel with controlling the individual distortions read from the primary and the secondary storage data devices and the correctness of command codes interpretation by the processor, additionally to check the processor command byte structure integrity, i.e. the sequential byte reading of multi-byte commands, in which the appeal to the memory cells is performed so that the address of the subsequent memory cell must differ exactly by a one from the address of the preceding memory cell until all bytes of a multi-byte command will be read, what increases the probability of prompt detection of the fact of accidental processor "walks" occurrence in case of failures in the microcomputer address or commands counter buses.;EFFECT: expanding the functionalities due to the operational control in the operating mode of the multi-byte commands byte structure integrity.;2 dwg
