Patent number: 4787033Abstract: Devices for interconnection into a digital computer system contain arbitration mechanisms for assigning control of a common communications path among the devices. Several modes of device arbitration are provided for, and the modes may be mixed among devices, and changed during operation of the system, in the system without interfering with communications. The arbitration mechanism requires only a single additional line in the communications pathway, and thus a single additional pin on the integrated circuit on which it is implemented, for the arbitration function. It thus facilitates implementation of the arbitration mechanism along with all other interconnect logic on a single integrated circuit.Type: GrantFiled: September 22, 1983Date of Patent: November 22, 1988Assignee: Digital Equipment CorporationInventors: Frank C. Bomba, William D. Strecker, Steven R. Jenkins

Patent number: 4661905Abstract: Control of a communications path interconnecting separate devices in a digital computer system is provided by only two signals generated and received locally within each device on the path and asserted on a systems-wide basis on two separate lines of the path. The generation and utilization of the control signals is independent of the physical location of the devices on the path, and position-dependent delays in transmission of the signals from one device to another are avoided.Type: GrantFiled: September 22, 1983Date of Patent: April 28, 1987Assignee: Digital Equipment CorporationInventors: Frank C. Bomba, Reinhard Schumann, Steven R. Jenkins, Paul Binder

Patent number: 3999163Abstract: A secondary storage facility including magnetic tape, disk or drum units or other sequential access storage units. Each storage unit or drive connects to a controller by means of a device bus with asynchronous and synchronous paths. Status and controller information is coupled between the controller and a selected drive unit asynchronously over the asynchronous bus.
