Inbound packets received by a physical network adapter of a processing device are routed by evaluating an inbound frame to determine if an inbound frame destination MAC address is associated with the processing device and determining whether the inbound frame should be routed to a corresponding logical interface or to drop the inbound frame if the inbound frame destination MAC address is equal to a virtual MAC address supported by the processing device. If it is determined that the inbound frame should be routed to the corresponding logical interface, then any necessary layer 3 functions are performed and the inbound frame is routed to the corresponding logical interface, thereby combining both layer 2 and layer 3 routing into a single logical function.

An equalizer provided in a digital transmitter compensates for attenuation in a signal channel to a digital receiver. The equalizer generates signal levels as a logical function of bit history to emphasize transition signal levels relative to repeated signal levels. The preferred equalizer includes an FIR transition filter using a look-up table. Parallel circuits including FIR filters and digital-to-analog converters provide a high speed equalizer with lower speed circuitry. The equalizer is particularly suited to in-cabinet and local area network transmissions where feedback circuitry facilitates adaptive training of the equalizer.

A dynamic logic register including a complementary pair of evaluation devices, delayed inversion logic, a dynamic evaluator, latching logic, and a keeper circuit coupled to the output. The evaluation devices are responsive to a clock signal and provide a pre-charged node and an evaluation node. The delayed inversion logic outputs a complete signal that is a delayed and inverted version of the clock signal. The dynamic evaluator, coupled between the pre-charged and evaluation nodes, evaluates a logic function based on a data signal during an evaluation period between operative edges of the clock and complete signals. The latching logic enables the state of an output node to be determined by the state of the pre-charged node during the evaluation period and otherwise clamps the pre-charged node to prevent perturbations of the data signal from propagating to the output node.
