Abstract
An error detection system is disclosed for not only indicating but eliminating certain errors which may occur during the transfer of information between communication busses in a data processing system wherein plural communication busses each provide a common information path to plural data processing units including memory units, peripheral control units, central processing units and ISL units, and wherein each of the plural communication busses are in electrical communication with an ISL unit, and ISL units are electrically connected in pairs. The error detection system requires no special supporting software or firmware on the part of any data processing unit on any of the communication busses.
