ABSTRACT:
A method for communicating between two, or more, devices comprises the steps of (1) allocating, in a receiving device, a plurality of input buffers linked in a circular queue for continuous reading of data; (2) setting up a timer for determining the end of received data streams; (3) receiving a variable-length bit stream comprising data; synchronization of data; (5) determining whether data is being received upon expiration of the timer; (6) resynchronizing for a subsequent bit stream if not receiving data in step (5); (7) checking one of the plurality of input buffers for idle patterns if data is being received in step (5); (8) restarting the timer and returning to step (4), when idle patterns are not detected in step (7); and (9) disabling the receiver and resynchronizing and returning to step (4), when idle patterns are received in step (7).
