Patents by Inventor Marco Portinari

Marco Portinari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for transmitting circuitry that transmit data at different rates
    Patent number: 7602724
    Abstract: A system for transmitting data to a first circuit that transmits and receives data at a first rate from a second circuit that transmits data at second rate that is greater than the first rate. This invention includes an interface that transmits pause frames to the second circuit in response to an event in order to halt transmission from the second circuit to the first circuit. The second circuit then halts transmitting data until a message to resume transmission is received.
    Type: Grant

    Date of Patent: October 13, 2009
    Assignee: Cisco Technology, Inc.
    Inventors: Gabriele Maria Galimberti, Roberto Gianella, Marco Portinari, Paolo Sironi
  • Recoverable reference clock architecture for SONET/SDH and ethernet mixed bidirectional applications
    Patent number: 7542483
    Abstract: Systems and methods for employing asynchronous transceivers in synchronous data communications. For example, a 10 Gigabit Ethernet transceiver may be used to support SONET/SDH communications with or without G.709 coding. Such a transceiver is clocked with a recovered clock signal when a received synchronous signal is available and with a locally generated clock when no such remotely generated signal is available.

  • JTAG and boundary scan automatic chain selection
    Patent number: 7191265
    Abstract: A printed circuit board (PCB) may be used in a first mode where boundary scan techniques are used to externally program and/or test devices on the PCB, or a second mode where an internal source programs devices using boundary scan techniques. In one implementation, there is also additional flexibility to include or skip devices in a boundary scan chain and to accommodate non-scan related functions for pins used for scanning. These various modes of operation may be selected by activating and deactivating buffers.
