1. System for memory management of data consistency relating to a main memory accessible by at least two processors, at least one of the said processors being furnished with at least one cache memory associated with at least one area of the main memory, referred to as the assignment area of the said processor, the said management system comprising: an assembly for management of shared access of the said processors to at least one common area of the main memory, referred to as the exchanges area, at least one copy module respectively associated with at least a first of the said processors furnished with at least one cache memory, capable of performing a data copy between a memory workspace consisting of one of the said cache memories and/or the assignment area of the said first processor, on the one hand, and the exchanges area, on the other hand, and at least one data transfer module, associated respectively with at least one second processor capable of exchanging data with the said first processor, intended for transferring data between the said exchanges area and the said associated second processor, characterized in that the said consistency management system also comprises triggering means controlled by the second processors, capable of triggering the copy modules of the first processors and the transfer modules of the second processors when the said first processors submit requests involving transfers of data between the said memory workspaces of the first processors and the second processors.
