  • Signal conditioner discovery and control in a multi-segment data path
    Patent number: 9940298
    Abstract: In a segmented data path, a source is able to “discover” whether any tunable repeater nodes are present. When one or more tunable repeaters are discovered, the source may adjust its link initialization sequence accordingly to train each “hop” individually and thereafter individually configure each intermediary repeater.
    Type: Grant

  • CONFIGURABLE SERIAL COMMUNICATION HUB
    Publication number: 20160371206
    Abstract: An apparatus and method for configuring a serial communication hub are disclosed herein. A serial communication hub includes an upstream port, a plurality of downstream ports, and a port controller. The port controller is configured to: arrange each of a first of the downstream ports and a second of the downstream ports to individually operate as a first type of serial communication interface; and to arrange the first of the downstream ports and the second of the downstream ports to operate in combination as a second type of serial communication interface.

  • System, method, and device for accelerated graphics port linking
    Patent number: 7079149
    Abstract: The invention provides systems, devices, and methods for using more than one Accelerated Graphics Port (AGP) to process graphics for a single computer monitor (282). In one embodiment, the invention is a method of providing advanced/high-performance AGP capabilities to a laptop computer by intercepting AGP signals from a laptop having a low-power AGP (224) and converting the AGP signals to signals for a high-performance AGP (270).

  • Low pin count (LPC) I/O bridge
    Patent number: 6990549
    Abstract: A low pin count (LPC) input/output (I/O) bridge device and method for a portable computer having a plurality of legacy ports and a docking connector. The LPC I/O bridge device includes an LPC controller coupled to the legacy ports and docking connector. The LPC controller is adapted to detect whether the portable computer is coupled to a docking station via the docking connector and route data transmissions to the legacy ports, docking connector, or both, based on information received from an LPC interface. Serialization logic coupled to the LPC controller serializes data transmissions routed to the docking connector.
