摘要： Forwarding decisions for Internet Protocol packets/frames are provided. An IP address from received packets/frames is extracted and split into portions or parts, a prefix, offset and suffix. A prefix table is used to identify an entry with a longest match to the prefix. A base address is retrieved from the identified entry to generate an identifier used to locate another entry in another table. The other identified entry provides receiver data or information regarding the intended destination.

摘要： Methods, apparatuses, and systems are presented for performing adaptive equalization involving receiving a signal originating from a channel associated with inter-symbol interference, filtering the signal using a filter having a plurality of adjustable tap weights to produce a filtered signal, and adaptively updating each of the plurality of adjustable tap weights to a new value to reduce effects of inter-symbol interference, wherein each of the plurality of adjustable tap weights is adaptively updated to take into account a constraint relating to a measure of error in the filtered signal and a constraint relating to group delay associated with the filter. Each of the plurality of adjustable tap weights may be adaptively updated to drive group delay associated with the filter toward a target group delay.

摘要： Output clock adjustment for a digital I/O between physical layer devices and media access controller. A method is disclosed for transferring data received on the input of a physical layer device from a transmission medium to an output associated with the physical layer device and to a media independent layer, the transferred data associated with transferred timing information from the physical layer device to the media independent layer. A receive clock is generated and then the data transitions in the received data are synchronized to at least one edge of the receive clock to provide synchronized receive data. The synchronized received data is then transmitted to the media independent layer. The generated receive clock is delayed by a predetermined clock delay to provide a delayed receive clock, and wherein the data transitions in the synchronized receive data is positioned relative to the rising edge of the delayed receive clock at a predetermined position therein following the rising edge thereof. The delayed receive clock transmitting with the transmitted synchronized receive data.

摘要： An apparatus associated with a device connected to a data loop processes data received from the data loop to determine whether data from the data loop is to be routed back to the data loop. The apparatus may determine how to route data based on an analysis of whether the device is authorized to participate in a conversation currently associated with the data loop. Thus, latency otherwise imparted by the device when the device processes the data may be avoided.

摘要： A method for performing adaptive equalization is presented comprising receiving a Forward Error Correction (FEC) encoded signal from a channel, filtering the received FEC encoded signal using a filter according to at least one adjustable filter coefficient to produce a filtered signal, evaluating the filtered signal to generate a signal error output, adjusting the at least one adjustable filter coefficient in response to the signal error output, performing FEC decode processing dependent on the filtered signal to generate an FEC output, and adjusting the at least one adjustable filter coefficient in response to the FEC output. In one embodiment, the signal error output relates to Mean Squared Error (MSE), and the FEC output relates to bit error rate. The at least one adjustable filter coefficient may be first adjusted in response to the signal error output until a specified condition is met, then adjusted in response to the FEC output.

摘要： Method and apparatus for configuring the operation of an integrated circuit. An integrated circuit with external programming capabilities is disclosed. A pin current source is provided for interfacing with at least one pin on the integrated circuit to control current flow there through to an external load interfaced to the at least one pin external to the integrated circuit. The external load has at least two discrete values. A voltage detector detects the voltage on the at least one pin and a state detector then compares the voltage on the at least one pin to at least two discrete voltage thresholds. Each of the discrete voltages is associated with a separate value of a control word, and the state detector is operable to determine the value of the control word associated with the detected voltage. The state detector then outputs the determined value of the control word.

摘要： The present invention is directed to a method and an apparatus where the standard wire bonding of TBGA's is replaced using a solid intermediate subcarrier on which the die may be flip chipped and which may then be flip chipped onto the substrate. The subcarrier has a number of conductors replacing the wire bond. In this manner, a better reflection suppression, better impedance matching, smaller conductor pitch and other advantages are achieved. The subcarrier may also be used for mounting multiple dies in a single substrate.
