  • Patent number: 10572373
    Abstract: Embodiments for automated testing of a virtualization management system are described. An example computer-implemented method for automated testing of a virtualization management system includes sending, by a test server, a test case to a plurality of instances of the system under test, the test case sent to each instance of the system under test via each interface from a plurality of interfaces supported by the system under test. The method further includes, for each instance of the system under test, performing multi-interface comparison. The comparison includes comparing, by the test server, responses to the test case from each of the interfaces. The method also includes in response to the responses from each of the interfaces being identical, storing the responses in an instance-response file corresponding to the instance. The method also includes reporting, by the test server, an error in response to the responses from each interface not being identical.

  • Patent number: 10510094
    Abstract: Internet advertising to users of web browser personal computer systems is a very large and mature industry. However, many new digital devices such as cellular telephones, table computer systems, and video game console are now presenting an even larger internet advertising market. Although the techniques used for targeting advertisements to web browsers on personal computers are sophisticated, the techniques for accurately targeting internet advertisements to these new digital devices are limited. To improve the quality of targeting advertisements on new digital devices a set of techniques for accurately pairing digital identities is disclosed. Once various digital identities are linked, all of the accumulated digital profile information from these linked digital identities may be used to accurately select advertisements for all of the linked digital devices.

  • Patent number: 8829958
    Abstract: An integrated circuit (“IC”) may include clock and data recovery (“CDR”) circuitry for recovering data information from an input serial data signal. The CDR circuitry may include a reference clock loop and a data loop. A retimed (recovered) data signal output by the CDR circuitry is monitored by other control circuitry on the IC for a communication change request contained in that signal. Responsive to such a request, the control circuitry can change an operating parameter of the CDR circuitry (e.g., a frequency division factor used in either of the above-mentioned loops). This can help the IC support communication protocols that employ auto-speed negotiation.

  • Patent number: 8416898
    Abstract: A circuit includes a receiver circuit, a decision feedback equalizer circuit, and a control loop circuit. The receiver circuit receives a data signal and generates an input signal in response to the data signal. The decision feedback equalizer circuit includes a tap driver and a first current source coupled to the tap driver. The tap driver drives the input signal based on a tap weight. The control loop circuit varies a current through the first current source based on variations in the input signal to reduce changes in the tap weight that are caused by the variations in the input signal.

  • Patent number: 8208523
    Abstract: Equalization of an incoming data signal can be controlled by sampling that signal at times when data values in that signal should be stable (“data samples”) and when that signal should be in transition between successive data values that are different (“transition samples”). A transition sample that has been taken between two successive differently valued data samples is compared to a reference value (which can be one of those two data samples). The result of this comparison can be used as part of a determination as to whether to increase or decrease equalization of the incoming data signal.

  • Patent number: 8208528
    Abstract: Adaptation convergence in an adaptive dispersion compensation engine (ADCE) of a high-speed serial interface is detected by monitoring the output of the error amplifier of one or more adjustment loops of the ADCE. Adaptation convergence is considered to have been detected upon detection of a predetermined number of transitions in the error amplifier output, each of which occurs within a preselected interval following the previous transition. The detector may be implemented with a timer that times the preselected interval and a counter that counts transitions in the error amplifier output. The timer restarts each time a transition occurs, and the counter outputs a convergence signal when it reaches the predetermined number, but is reset each time the timer reaches the preselected interval. The serial interface may be part of a programmable integrated circuit device and in any case the preselected interval and the predetermined number may be programmable.

  • Patent number: 8175143
    Abstract: A method, and circuitry, for choosing the correct equalization curve in adaptive equalization uses a feedback loop in which the incoming high-speed serial data are digitized and deserialized for use in the remainder of the device, and also are used by an adaptive state machine to both extract the reference levels for digitization and to control the equalization curve. Detection of the reference level and selection of the equalization curve may be performed at a different rates to avoid interfering with one another. The state machine preferably is programmable. This is useful in any device, but is particularly well-suited for a programmable device, such as a PLD or other programmable integrated circuit device, where conditions may vary according a user logic design.

  • Patent number: 8098087
    Abstract: A method and apparatus is provided for standby voltage offset cancellation at inputs to a comparator within a receiver channel. Each of a first comparator input and second comparator input is isolated from an input signal such that each of the first and second comparator inputs attains a respective standby voltage level. A voltage level on one of the first and second comparator inputs is incrementally changed, while the output signal of the comparator is monitored. Upon detecting a state transition in the output signal of the comparator, the incremental changing of the voltage level on the one comparator input is stopped at a final voltage level setting. The final voltage level setting is stored in a computer memory for reference in setting of the voltage level at the one comparator input so as to compensate for the standby voltage offset at the inputs to the comparator.
