  • Bus interface units sharing a common bus using distributed control for allocation of the bus
    Patent number: 4373183
    Abstract: A distributed data processing system is disclosed which has truly distributed control. A plurality of bus interface units (BIU) are interconnected by the distributed system data bus (DSDB) which includes a clock line, a serial command line (CMD), a serial bus allocation line (BAL) and a two byte wide data bus. A central clock connected to the clock line which defines the message frame timing, is the only centralized "control" element in the system. Each BIU may in turn be connected to either one or several data processing units, an I/O port, or a bridge connecting to still another similar bus network.
