    摘要： A data processing system includes data processing adapters (2) for controlling the data transfers between end systems (1) and a memory through contention type busses (7 and 11) and a control processor connected to the system bus (7) for through a coupler (8) for controlling the physical resources such as registers or memories of the whole data processing system. A control operation is initiated by the control processor which presents on its processor bus (14) a control operation to be executed in a destination unit which can be the coupler, a selected data processing adapter or a selected end system. Each unit is provided with a control operation interface dedicated to the processing of the control operation or its forwarding toward the destination unit and the preparation of a response to the control operation in the destination unit and the propagation of the response toward the coupler, so as to minimize the bus occupancy times.
