High speed circular data bus system

A high speed circular data bus system for a communication system having a plurality of data receivers and demodulator units asynchronously generating demodulated input data and a plurality of modulator units and data transmitters transmitting modulated output data, wherein the data bus system routes data from the demodulator units to the modulator units, said data bus system comprising:

• a plurality of input buffers connected to each other in a daisy chain circular configuration, each input buffer of said plurality of input buffers adapted to receive demodulated input data asynchronously with respect to one another from a respective one of said plurality of demodulator units, said plurality of input buffers are operative to transfer the data received by each input buffer of said plurality of input buffers to a next sequential input buffer in a predetermined sequence until the input data received from each demodulator unit is circulated to each input buffer of said plurality of input buffers;
• and
• a plurality of output buffer slices, each output buffer slice of said plurality of output buffer slices being associated with and connected to a respective one of said input buffers for receiving the data of its associated input buffer as the associated input buffer is transferring the data to the next sequential input buffer, each output buffer slice having at least one output buffer connected to an associated one of said data modulator units, each output buffer selectively transferring the data received from its associated input buffer to said associated modulator unit for retransmission.
