Abstract

Computer coupling unit for m of n computers, carrying out comparison and checking functions on the basis of data compression followed by a comparison of signatures, characterised in that a first control device 1 linked to the bus AB, SB, DB is coupled by means of a first address bus, of a bidirectional data bus and of a single-directional control bus AB1, DB1, SB1 with a signature and memory unit 2, in that the first control device 1 is linked over a second address bus, over a bidirectional data bus, and over a control bus AB2, DB2, SB2 with a second control device 3, and in that the signature and memory unit 2 is linked by means of another unidirectional data bus DB3 to a second control device 3. <IMAGE>
