Modem instructions sequentially alternating executions between sending a predetermined number of symbols by a transmit sequencer and receiving by a receive sequencer

摘要

A modem is implemented using a host processor or DSP and has execution code for implementing respective receive and transmit functionality which execute without any branching. Coordination of receive and transmit functionality is achieved using state indications in a common data area. Operation without branching eliminates the need for machine cycles associated with branching.
