摘要： Aspects of a method and system for unconstrained frequency domain adaptive filtering include one or more circuits that are operable to select one or more time domain coefficients in a current filter partition. A value may be computed for each of the selected one or more time domain coefficients based on a corresponding plurality of frequency domain coefficients. The corresponding plurality of frequency domain coefficients may be adjusted based on the computed values. A subsequent plurality of frequency domain coefficients in a subsequent filter partition may be adjusted based on the computed values. Input signals may be processed in the current filter partition based on the adjusted corresponding plurality of frequency domain coefficients. A time-adjusted version of the input signals may be processed in a subsequent filter partition based on the adjusted subsequent plurality of frequency domain coefficients.

摘要： Embodiments of the present invention enable robust and quick parallel detection of the remote LPI request signal (rem_lpi_req) and SEND ZERO mode (SEND_Z) defined in the Energy Efficient Ethernet (EEE) standard. Embodiments do not rely on energy detection for detecting SEND_Z. Therefore, SEND_Z can be detected reliably and with minimal latency. In addition, since SEND_Z and rem_lpi_req are detected in parallel, embodiments are not concerned with the false detection of rem_lpi_req (before SEND_Z is detected) or the need to disable detection of rem_lpi_req (after SEND_Z is detected).

摘要翻译： 本发明的实施例能够实现在能效以太网（EEE）标准中定义的远程LPI请求信号（rem_lpi_req）和SEND ZERO模式（SEND_Z）的鲁棒且快速的并行检测。 实施例不依赖于检测SEND_Z的能量检测。 因此，可以可靠地检测SEND_Z并以最小的延迟。 另外，由于并行地检测到SEND_Z和rem_lpi_req，实施例不涉及rem_lpi_req的错误检测（在检测到SEND_Z之前）或者需要禁止检测rem_lpi_req（在检测到SEND_Z之后）。

摘要： A method and computer program product for detecting faults in cables. The invention comprises receiving a first reflected signal; comparing the first reflected signal amplified with a first predetermined receiver gain setting with a first threshold; if the value of the amplified first reflected signal is greater than the value of the first threshold, then terminating detecting; if the value of the amplified first reflected signal is not greater than the value of the first threshold, then comparing a second reflected signal amplified with a second predetermined gain setting different from the first gain setting with a second threshold.

摘要： An Ethernet PHY may receive an indication from a local timing source that a local clock is suitable for propagation to a link partner. In response, a timer in the Ethernet PHY may be started. In instances that the Ethernet PHY receives, during a time period subsequent to starting the timer and before the timer reaches a predetermined value, an indication that the link partner is propagating a clock that is suitable for the Ethernet PHY to synchronize to, the Ethernet PHY may be configured as timing slave. In instances that the Ethernet PHY does not receive, during the time period subsequent to starting the timer and before the timer reaches a predetermined value, an indication that the link partner is propagating a clock that is suitable for the Ethernet PHY to synchronize to, Ethernet PHY may be configured as timing master upon the timer reaching the predetermined value.

摘要： A system and method for dynamic power control for energy efficient physical layer communication devices. Energy-efficiency features are continually being developed to conserve energy in links between such energy-efficient devices. These energy-efficient devices interoperate with many legacy devices that have already been deployed. In these links, energy savings can be produced by having a local receiver enter an energy saving state based upon the receipt of standard IDLE signals.
