Abstract: One aspect of the invention is a multichannel facility datalink processor. The processor comprises input circuitry operable to receive a first plurality of facility datalink signals. In addition, the multichannel facility datalink processor comprises output circuitry operable to transmit a second plurality of facility datalink signals. A state machine operable to be loaded with a predetermined state also forms a portion of the processor and is further operable to process ones of the first plurality of facility datalink signals and ones of the second plurality of facility datalink signals. The processor further comprises storage circuitry coupled to the state machine which is operable to store state information and facility datalink data for each of the first plurality of facility datalink signals and each of the second plurality of facility datalink signals.

Abstract: One aspect of the invention is a shared signal processor comprising input circuitry to receive a plurality of input signals and output circuitry operable to transmit a plurality of output signals. Storage circuitry is operable to store state information and signal data for each of the plurality of input signals and output signals. A state machine is coupled to the input circuitry, output circuitry, and storage circuitry and is operable to poll each input signal and output signal to identify a first signal requiring processing. The state machine is further operable to load the state information and signal data associated with the first signal and process the first signal.
