Abstract A circuit arrangement is described for the connecting of system units constituting a program controlled data processing system. These system units are data processors and storage units. The individual system units are redundantly connected in multiplex fashion in order to insure system reliability. That is, a given defective system unit will be replaced by a like redundantly provided system unit, while the defective unit is placed in a testing state and isolated from the rest of the system. The redundance of the various processors may be provided for by providing them either in duplicate or in triplicate. Each said processor contains two standard data terminals. The individual processors are cyclically connected to storage units provided in triplicate, and these storage units which are equipped with a plurality of parallel, standard data terminals. Thus, at any given time, two like processing units are connected to one of the storage units.
A circuit arrangement for connecting system units constituting a program controlled data processing system, said system units being data processing units and storage units, each of said processing units and storage units of a like kind being redundantly provided in such a manner that one of said units, when defective, will be replaced by a like unit, comprising: a plurality of data processing units of different kinds, each kind of processing unit being redundantly provided in one of duplicate or triplicate, each said processing unit having at least two standard data terminals, storage units provided in triplicate and having a plurality of parallel standard data terminals and means connecting said processing and storage units such that each said redundantly provided processing unit is connected to two of said storage units, each identical processing unit being connected to a different combination of storage units.
