A system for interchanging data between 'agent' data processor units including processing means such as processors. Units are interconnected by an external multiwire interchange bus common to said units, with sharing the bus being orchestrated by an arbitrator. Each unit has storage means in which data is stored in an organized manner at determined addresses enabling the data to be read and/or written on demand. The whole formed by said units includes data storage means constituting a distributed interchange memory assembly common to all of the units and accessible by all of them via the interchange bus. Each unit contains a portion of the means of the assembly, constituted by an interchange memory which is accessible by the processor means of the unit, and by the processor means of another unit via the interchange bus.
