ABSTRACT:
A node for obtaining access to a bus. In this arbitration method, the node receives a conditional grant. The node determines whether access to the bus will actually transfer to it. The node contains distributed logic that examines an extend bus cycle signal to determine whether it can become a transmitter to transfer messages on the bus. When the node becomes a transmitter, it generates an extend bus cycle signal to maintain access to the bus when executing a multi-cycle transfer, even though other nodes, perhaps with higher priorites, require access to the bus.
