Patent number: 8812287Abstract: A method and device for preserving the wired-OR nature of the clock signal connection between two devices without a direct analog connection between the lines and in an infinitely scalable fashion. The method includes detecting a logic state at a first connector and a second connector and driving an appropriate connector of the device to an active state in response to determining that a connector is driving an active state. The device includes first and second connectors for communicating logic states and driving active states in response to detected logic states.Type: GrantFiled: February 8, 2011Date of Patent: August 19, 2014Assignee: International Business Machines CorporationInventor: Daniel J Barus

Patent number: 7353308Abstract: In a bi-directional, self-synchronous bus for communication between semiconductor devices, a logic delay is provided as a flag to a state machine control for indicating that the bus is making a transition from a low to a high state. The logic delay causes the bus to adaptively idle until the bus settles, making it amenable for a wide variety of bus sizes and topologies. In this way, oscillation of the bus is avoided without slowing the speed of the state machine clock.Type: GrantFiled: October 20, 2005Date of Patent: April 1, 2008Assignee: International Business Machines CorporationInventors: Daniel J. Barus, Eileen M. Behrendt, Jeffrey R. Biamonte, Raymond J. Harrington, Timothy M. Trifilo
