ABSTRACT:
A communications system including a shared signal circuit for performing a set of signal processing operations on both receive data and transmit data. The signal processing circuit is also shared by a plurality of communication ports. To further enhance operation of the system, the computing resources include a set of independent application specific (ASIC) logic circuits, with at least some of the ASICs selectively performing at least one of a first signal processing operation and a second signal processing operation on data in response to control information embedded in an input data object.
