Abstract

A supervising device is described for detecting errors in an automatic progression of the addresses of words which must be sequentially read out from a store under the control of a command logic forming the starting address from an operation code and thereafter incrementing the address by combining a portion of each read-out word with other data. Said device comprises a code comparator the output of which is activated when a code of a restricted number of bits derived from the operation code and a code of the same number of bits derived from a read out word disagree except when this second code presents a particular configuration of bits as, for instance an all identical binary value bit configuration.
