ABSTRACT:
A data processing switching system is disclosed including system units comprising processing units and memory banks and at least one storage input/output control governing the information traffic between the processing units and the memory banks via communication channels. The system contains an input control and an output control establishing links for the traffic. A plurality of communication paths for the information traffic is governed by these controls, the controls being characterized by means for grouping the processing units (VE) and the memory banks (SB) into a plurality of groups in number equal to the number of the communication paths currently available for seizure between the processing units and the memory banks or between the memory banks and the processing units. The processing units and memory banks include means for sending input or output requests to said input or output control, respectively.
The input and output control includes means for evaluating these requests as a function of the priority of the sending system unit, and for comparing these requests on the basis of their respective destinations.
Means are provided responsive to these evaluating means for concurrently connecting at least one of the processing units requesting an input and at least one of the memory banks requesting an output to their respective destinations over the respective input or output circuit of the control means.
