In a preferred embodiment of the present invention, the host designator is a worldwide name. In a further embodiment of the present invention, the step is provided of determining if a mode parameter is set for a default O/S protocol; and selecting that default O/S protocol unless there is a match of the log-in request host designator in the table.

摘要： In some embodiments, an adaptive filter employs two adaptation modes, where during one adaptation mode the adaptive filter is updated only when the received training sample is a first binary value and during the other adaptation mode the adaptive filter is updated only when the received sample is a second binary value. Each adaptation mode provides a set of filter weights, and these two sets of filter weights are averaged to provide an adapted set of filter weights. The use of two adaptation mode allows for a clock boundary in which the digital portion of the filter operates at a lower clock rate than the analog portion. In other embodiments, a filter architecture is described for providing the algebraic signs of the received data samples, important for sign-sign least means square filtering algorithms. In other embodiments, a filter architecture is described in which efficient use is made of voltage-to-current converters so as to achieve a high throughput rate during filtering. Embodiments of the present invention have application to channel equalization.

摘要： In some embodiments a passive impedance equalization network for high speed serial links is described. The impedance equalization network includes at least one stepped impedance transformer near points of impedance discontinuities. The impedance discontinuities may be at an interface connection between two circuit boards. The impedance discontinuities on a circuit board may be at a die-package interface and/or a package-board interface. The stepped impedance transformer may be formed in a package trace, a board trace or both. Forming the stepped impedance transformers in the traces requires no modification to existing package/board design methodology or technology. The stepped impedance transformers can provide impedance matching over a range of frequencies. To account for modeling errors in the design of the stepped impedance transformers integrated circuits transmitting data over the serial link may include active circuitry to select an output/input impedance for transmitters/receivers. Other embodiments are otherwise disclosed herein.
