1. A communications system comprising:

  • a digital data buffer circuit for storing digital data, said digital data including both receive data and transmit data; and

    a shared signal processing circuit for performing a set of signal processing operations on both said receive data and said transmit data, said shared signal processing circuit having computing resources shared by a receive task and a transmit task; and

    said computing resources including a set of independent application specific (ASIC) logic circuits interconnected by a local bus and using a common clock, said set of independent ASIC logic circuits including at least one multi-tasking ASIC logic circuit, and which multi-tasking ASIC logic circuit during a single period of said common clock selectively performs either a first signal processing operation on said receive data and/or a second signal processing operation on said transmit data.
