ABSTRACT:
An interconnection unit for connecting multiple data processing systems in a distributed data processing network. The interconnection unit comprises a single controller with control and data sections that connect to each data processing system in the network through an interface circuit and a host processor interface circuit that connects to each data processing system. For one data processing system to transfer information to an other system, the one system requests exclusive control of either the data or control section of the interconnection unit. Each section independently and sequentially tests each interface circuit to determine if a control request exists. When a section grants a request, the requesting data processing system transfers information to or from a memory in that section associated with another system in the network. That memory is accessible to all the data processing systems. The controller sends a signal to the other data processing system to notify it that pertinent information is stored in the memory. The other system then can request control of the interconnection unit and process that information.
