DATA PROCESSING SYSTEM IN WHICH UNRELIABLE WORDS IN THE MEMORY ARE REPLACED BY AN UNRELIABILITY INDICATOR

摘要

PHN 10.828 14 1.4.1984 "Data processing system in which unreliable words in the memory are replaced by an unreliability indicator". A data processing system comprising a memory receives data in the form of data blocks. Such a data block contains at least one data word and check bits. On the basis of the check bits it is verified whether the data block contains reliable or unreliable datawords. The unreliable data words are not written into the memory but are replaced by an unreliability indicator which is written into the memory at the address reserved for the unreliable dataword in question.
