Abstract
Different units of a system are identified by their device numbers. The device numbers are set during initialization as follows. Each unit has a pin connected to a unique line of the data bus. During initialization, a control unit drives the device number of each unit onto the corresponding line of the data bus. Arbitration cycles proceed in parallel with bus cycles. The above arbitration techniques are suitable to control access to shared resources other than a shared bus.
