METHOD FOR SHARING RESOURCES OF A DIGITAL DATA COMMETHOD FOR SHARING RESOURCES OF A DIGITAL DATA COMMUNICATION SYSTEM MUNICATION SYSTEM

摘要

The proposed method for sharing resources of a digital data communication system, which contains several subsystems, implies access to the data stored in the data bases of the subsystems according to a specified algorithm and timing signals. The method differs in that the writing data to the data base of the defined subsystem is accomplished via the processor of the main subsystem so that, within the writing interval, the communication between the terminals of the main subsystem is disabled. After writing the data, the possibility for the communication, according to timing signals, between the terminals of the subsystem while the access to the data bases of the other subsystems is disabled. In the data base of each subsystem, two memory pages are dedicated to be shared by the other subsystems.
