  • USB interface configurable for host or device mode
    Patent number: 8924598
    Abstract: Various embodiments provide a USB interface that can operate in either a Host or Device mode using standard Link and/or physical interface circuit (PHY) components which, in at least some embodiments, do not have additional circuitry that is utilized to implement the USB OTG standard.
    Type: Grant

  • Simplified universal serial bus (USB) hub architecture
    Patent number: 7657691
    Abstract: A Universal Serial Bus (USB) device uses a same elasticity buffer for buffering packets for multiple different ports and only necessary packet detection circuitry is associated with the individual ports. A collision detection circuit is further included corresponding with information received from the packet detection circuitry. This simplified universal elasticity buffer architecture reduces the complexity and cost of the USB device.

  • Method and apparatus for configuring an interface controller wherein ping pong FIFO segments stores isochronous data and a single circular FIFO stores non-isochronous data
    Patent number: 6745264
    Abstract: Hardware Description Language (HDL) code is created for an interface controller so that logic requiring device-specific configuration refers to a parameter file. This set of parameters lets components in a bridge circuit provide support for the same configuration. In another aspect of the invention, a control circuit identifies isochronous endpoints and non-isochronous endpoints. A buffer is configured into a first FIFO mode for isochronous endpoints and configured into a second FIFO mode for non-isochronous endpoints.
