Manufacturer:TOS Description:1) Single data bit errors cause 3 or 5 bits in the syndrome word to go low The columns of the check bit syndrome matrix (TABLE II) are the syndrome words for all single bit data errors in the 32 bit word (also see TABLE V) The data bit in error corresponds to the column in the check bit syndrome matrix that matches the syndrome word For instance the syndrome word indicating that data bit 31 is in error would be (CB6-CB0) e 0001010 see the column for data bit 31 in TABLE II or see TABLE V During mode 3 (S0 e S1 e 1) the syndrome word is decoded during single data bit errors and used to invert the bit in error thus correcting the data word The correct- ed word is made available on the data I O port (DB0 thru DB31) the check word I O port (CB0 thru CB6) presents the 7-bit syndrome error code This syndrome error code can be used to locate the bad memory chip |
